In Escherichia coli, the S2P homolog RseP is involved in the sigmaE pathway of extracytoplasmic stress responses. Also included in this group are such homologs as Bacillus subtilis YluC, Mycobacterium tuberculosis Rv2869c S2P, and Bordetella bronchiseptica HurP. Rv2869c S2P appears to have a role in the regulation of prokaryotic lipid biosynthesis and membrane composition and YluC of Bacillus has a role in transducing membrane stress. This group includes bacterial and eukaryotic S2P/M50s homologs with either one or two PDZ domains present. PDZ domains are believed to have a regulatory role. The RseP PDZ domain is required for the inhibitory reaction that prevents cleavage of its substrate, RseA.

>PF02163 Peptidase_M50: Peptidase family M50; InterPro: IPR008915 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This entry contains metallopeptidases belonging to MEROPS peptidase family M50 (S2P protease family, clan MM). Members of the M50 metallopeptidase family include: mammalian sterol-regulatory element binding protein (SREBP) site 2 protease, Escherichia coli protease EcfE, stage IV sporulation protein FB and various hypothetical bacterial and eukaryotic homologues. A number of proteins are classified as non-peptidase homologues as they either have been found experimentally to be without peptidase activity, or lack amino acid residues that are believed to be essential for the catalytic activity.; GO: 0004222 metalloendopeptidase activity, 0006508 proteolysis; PDB: 3B4R_A 3ID4_A 3ID2_A 2ZPL_B 3ID1_A 2ZPM_A 3ID3_B 2HGA_A.

In sterol-depleted mammalian cells, a two-step proteolytic process releases the N-terminal domains of SREBPs from membranes of the endoplasmic reticulum (ER). These domains translocate into the nucleus, where they activate genes of cholesterol and fatty acid biosynthesis. The first cleavage occurs at Site-1 within the ER lumen to generate an intermediate that is subsequently released from the membrane by cleavage at Site-2, which lies within the first transmembrane domain. It is the second proteolytic step that is carried out by the SREBP Site-2 protease (S2P) which is present in this CD family. This group appears to be limited to eumetazoan proteins and contains one PDZ domain.

>PF01434 Peptidase_M41: Peptidase family M41 This is family M41 in the peptidase classification. ; InterPro: IPR000642 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to MEROPS peptidase family M41 (FtsH endopeptidase family, clan MA(E)). The predicted active site residues for members of this family and thermolysin, the type example for clan MA, occur in the motif HEXXH. The peptidase M41 family belong to a larger family of zinc metalloproteases. This family includes the cell division protein FtsH, and the yeast mitochondrial respiratory chain complexes assembly protein, which is a putative ATP-dependent protease required for assembly of the mitochondrial respiratory chain and ATPase complexes. FtsH is an integral membrane protein, which seems to act as an ATP-dependent zinc metallopeptidase that binds one zinc ion.; GO: 0004222 metalloendopeptidase activity, 0005524 ATP binding, 0006508 proteolysis; PDB: 4EIW_C 2DHR_E 1IY1_A 1IY2_A 1IY0_A 1IXZ_A 2CE7_F 2CEA_F 3KDS_E 2QZ4_A ....

They are zinc-dependent, calcium-activated proteases synthesised as inactive precursors (zymogens), which are proteolytically cleaved to yield the active enzyme [, ]. All matrixins and related proteins possess 2 domains: an N-terminal domain, and a zinc-binding active site domain. The N-terminal domain peptide, cleaved during the activation step, includes a conserved PRCGVPDV octapeptide, known as the cysteine switch, whose Cys residue chelates the active site zinc atom, rendering the enzyme inactive [, ].

Members of the S2P/M50 family of RIP proteases use proteolytic activity within the membrane to transfer information across membranes to integrate gene expression with physiologic stresses occurring in another cellular compartment. In eukaryotic cells they regulate such processes as sterol and lipid metabolism, and endoplasmic reticulum stress responses. In prokaryotes they regulate such processes as sporulation, cell division, stress response, and cell differentiation. This group includes bacterial, eukaryotic, and Archaeal S2P/M50s homologs with a minimal core protein and no PDZ domains.

A calcium-binding domain c-terminal to the metalloprotease domain, which contains multiple tandem repeats of a nine-residue motif including the pattern GGxGxD, and which forms a parallel beta roll may be involved in the translocation mechanism and/or substrate binding.

This enzyme hydrolyzes peptides containing between 7 and 17 amino acids with fairly broad specificity. The PepF gene is duplicated in L. lactis on the plasmid that bears it, while a shortened second copy is found in Bacillus subtilis. Most bacterial PepFs are cytoplasmic endopeptidases; however, the PepF Bacillus amyloliquefaciens oligopeptidase is a secreted protein and may facilitate the process of sporulation. Specifically, the yjbG gene encoding the homolog of the PepF1 and PepF2 oligoendopeptidases of Lactococcus lactis has been identified in Bacillus subtilis as an inhibitor of sporulation initiation when over expressed from a multicopy plasmid.

>cd06258 Peptidase_M3_like The peptidase M3-like family, also called neurolysin-like family, is part of the "zincins" metallopeptidases, and includes M3, M2 and M32 families of metallopeptidases. The M3 family is subdivided into two subfamilies: the widespread M3A, which comprises a number of high-molecular mass endo- and exopeptidases from bacteria, archaea, protozoa, fungi, plants and animals, and the small M3B, whose members are enzymes primarily from bacteria. Well-known mammalian/eukaryotic M3A endopeptidases are the thimet oligopeptidase (TOP; endopeptidase 3.4.24.15), neurolysin (alias endopeptidase 3.4.24.16), and the mitochondrial intermediate peptidase. The first two are intracellular oligopeptidases, which act only on relatively short substrates of less than 20 amino acid residues, while the latter cleaves N-terminal octapeptides from proteins during their import into the mitochondria. The M3A subfamily also contains several bacterial endopeptidases, collectively called olig

>PF01447 Peptidase_M4: Thermolysin metallopeptidase, catalytic domain This Prosite motif covers only the active site. This is family M4 in the peptidase classification. ; InterPro: IPR013856 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases that belong to the MEROPS peptidase family M4 (thermolysin family, clan MA(E)). The protein fold of the peptidase domain of thermolysin, is the type example for members of the clan MA. The thermolysin family is composed only of secreted eubacterial endopeptidases. The zinc-binding residues are H-142, H-146 and E-166, with E-143 acting as the catalytic residue. Thermolysin also contains 4 calcium-binding sites, which contribute to its unusual thermostability. The family also includes enzymes from a number of pathogens, including Legionella and Listeria, and the protein pseudolysin, all with a substrate specificity for an aromatic residue in the P1' position. Three-dimensional structure analysis has shown that the enzymes undergo a hinge-bend motion during catalysis. Pseudolysin has a broader specificity, acting on large molecules such as elastin and collagen, possibly due to its wider active site cleft [].

>PF05572 Peptidase_M43: Pregnancy-associated plasma protein-A; InterPro: IPR008754 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to the MEROPS peptidase M43 (cytophagalysin family, clan MA(M)), subfamily M43. The predicted active site residues for members of this family and thermolysin, the type example for clan MA, occur in the motif HEXXH. The type example of this family is the pregnancy-associated plasma protein A (PAPP-A), which cleaves insulin-like growth factor (IGF) binding protein-4 (IGFBP-4), causing a dramatic reduction in its affinity for IGF-I and -II. Through this mechanism, PAPP-A is a regulator of IGF bioactivity in several systems, including the Homo sapiens ovary and the cardiovascular system [, , , ].; PDB: 3LUN_A 3LUM_B 2J83_A 2CKI_A.

Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to the MEROPS peptidase family M12, subfamily M12A (astacin family, clan MA(M)). The protein fold of the peptidase domain for members of this family resembles that of thermolysin, the type example for clan MA and the predicted active site residues for members of this family and thermolysin occur in the motif HEXXH []. The astacin () family of metalloendopeptidases encompasses a range of proteins found in hydra to humans, in mature and developmental systems []. Their functions include activation of growth factors, degradation of polypeptides, and processing of extracellular proteins []. The proteins are synthesised with N-terminal signal and pro-enzyme sequences, and many contain multiple domains C-terminal to the protease domain. They are either secreted from cells, or are associated with the plasma membrane. The astacin molecule adopts a kidney shape, with a deep active-site cleft between its N- and C-terminal domains []. The zinc ion, which lies at the bottom of the cleft, exhibits a unique penta-coordinated mode of binding, involving 3 histidine residues, a tyrosine and a water molecule (which is also bound to the carboxylate side chain of Glu93) []. The N-terminal domain comprises 2 alpha-helices and a 5-stranded beta-sheet. The overall topology of this domain is shared by the archetypal zinc-endopeptidase thermolysin. Astacin protease domains also share common features with serralysins, matrix metalloendopeptidases, and snake venom proteases; they cleave peptide bonds in polypeptides such as insulin B chain and bradykinin, and in proteins such as casein and gelatin; and they have arylamidase activity [].; GO: 0004222 metalloendopeptidase activity, 0006508 proteolysis; PDB: 3LQB_A 3EDH_A 3EDG_A 3EDI_A 1IAE_A 1IAB_A 1IAA_A 1AST_A 1IAC_A 1QJJ_A ....

This group of metallopeptidases belong to the MEROPS peptidase family M7 (snapalysin family, clan MA(M)). The protein fold of the peptidase domain for members of this family resembles that of thermolysin, the type example for clan MA. With a molecular weight of around 16kDa, Streptomyces extracellular neutral protease is one of the smallest known proteases []; it is capable of hydrolysing milk proteins []. The enzyme is synthesised as a proenzyme with a signal peptide, a propeptide and an active domain that contains the conserved HEXXH motif characteristic of metalloproteases. Although family M7 shows active site sequence similarity to other members, it differs in one major respect: the third zinc ligand appears to be an aspartate residue rather than the usual histidine.; GO: 0004222 metalloendopeptidase activity, 0008270 zinc ion binding, 0006508 proteolysis, 0005576 extracellular region; PDB: 1C7K_A 1KUH_A.

Meprins are membrane-bound or secreted extracellular proteases, which cleave a variety of targets, including peptides such as parathyroid hormone, gastrin, and cholecystokinin, cytokines such as osteopontin, and proteins such as collagen IV, fibronectin, casein and gelatin. Meprins may also be able to release proteins from the cell surface. Closely related meprin alpha- and beta-subunits form homo- and hetero-oligomers; these complexes are found on epithelial cells of the intestine, for example, and are also expressed in certain cancer cells.

>cd06460 M32_Taq Peptidase family M32 is a subclass of metallocarboxypeptidases which are distributed mainly in bacteria and archaea, and contain a HEXXH motif that coordinates a divalent cation such as Zn2+ or Co2+, so far only observed in the active site of neutral metallopeptidases but not in carboxypeptidases. M32 includes the thermostable carboxypeptidases (E.C. 3.4.17.19) from Thermus aquaticus (TaqCP) and Pyrococcus furiosus (PfuCP), which have broad specificities toward a wide range of C-terminal substrates that include basic, aromatic, neutral and polar amino acids. These enzymes have a similar fold to the M3 peptidases such as neurolysin and the M2 angiotensin converting enzyme (ACE). Novel peptidases from protozoa Trypanosoma cruzi, a causative agent of Chagas' disease, and Leishmania major, a parasite that causes leishmaniasis, are the first eukaryotic M32 enzymes identified so far, thus making these enzymes an attractive potential target for drug development against these o

>PF01421 Reprolysin: Reprolysin (M12B) family zinc metalloprotease This Prosite motif covers only the active site.; InterPro: IPR001590 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to the MEROPS peptidase family M12, subfamily M12B (adamalysin family, clan (MA(M)). The protein fold of the peptidase domain for members of this family resembles that of thermolysin, the type example for clan MA and the predicted active site residues for members of this family and thermolysin occur in the motif HEXXH []. The adamalysins are zinc dependent endopeptidases found in snake venom. There are some mammalian proteins such as P78325 from SWISSPROT, and fertilin Q28472 from SWISSPROT. Fertilin and closely related proteins appear to not have some active site residues and may not be active enzymes.

There are two forms of the enzyme in humans, the ubiquitous somatic ACE and the sperm-specific germinal ACE, both encoded by the same gene through transcription from alternative promoters. Somatic ACE has two tandem active sites with distinct catalytic properties, whereas germinal ACE, the function of which is largely unknown, has just a single active site. Recently, an ACE homolog, ACE2, has been identified in humans that differs from ACE; it preferentially removes carboxy-terminal hydrophobic or basic amino acids and appears to be important in cardiac function. ACE homologs (also known as members of the M2 gluzincin family) have been found in a wide variety of species, including those that neither h

Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to MEROPS peptidase family M48 (Ste24 endopeptidase family, clan M-); members of both subfamily are represented. The members of this set of proteins are mostly described as probable protease htpX homologue (3.4.24 from EC) or CAAX prenyl protease 1, which proteolytically removes the C-terminal three residues of farnesylated proteins. They are integral membrane proteins associated with the endoplasmic reticulum and Golgi, binding one zinc ion per subunit. In Saccharomyces cerevisiae (Baker's yeast) Ste24p is required for the first NH2-terminal proteolytic processing event within the a-factor precursor, which takes place after COOH-terminal CAAX modification is complete. The Ste24p contains multiple predicted membrane spans, a zinc metalloprotease motif (HEXXH), and a COOH-terminal ER retrieval signal (KKXX). The HEXXH protease motif is critical for Ste24p activity, since Ste24p fails to function when conserved residues within this motif are mutated. The Ste24p homologues occur in a diverse group of organisms, including Escherichia coli, Schizosaccharomyces pombe (Fission yeast), Haemophilus influenzae, and Homo sapiens (Human), which indicates that the gene is highly conserved throughout evolution. Ste24p and the proteins related to it define a subfamily of proteins that are likely to function as intracellular, membrane-associated zinc metalloproteases []. HtpX is a zinc-dependent endoprotease member of the membrane-localized proteolytic system in E. coli, which participates in the proteolytic quality control of membrane proteins in conjunction with FtsH, a membrane-bound and ATP-dependent protease. Biochemical characterisation revealed that HtpX undergoes self-degradation upon cell disruption or membrane solubilization. It can also degraded casein and cleaves solubilized membrane proteins, for example, SecY [].

>PF05548 Peptidase_M11: Gametolysin peptidase M11; InterPro: IPR008752 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to the MEROPS peptidase family M11 (gametolysin family, clan MA(M)). The protein fold of the peptidase domain for members of this family resembles that of thermolysin, the type example for clan MA and the predicted active site residues for members of this family and thermolysin occur in the motif HEXXH []. The type example is gametolysin from the unicellular biflagellated alga, Chlamydomonas reinhardtii Gametolysin is a zinc-containing metallo-protease, which is responsible for the degradation of the cell wall. Homologues of gametolysin have also been reported in the simple multicellular organism, Volvox [, ].

>PF02074 Peptidase_M32: Carboxypeptidase Taq (M32) metallopeptidase; InterPro: IPR001333 In the MEROPS database peptidases and peptidase homologues are grouped into clans and families. Clans are groups of families for which there is evidence of common ancestry based on a common structural fold: Each clan is identified with two letters, the first representing the catalytic type of the families included in the clan (with the letter 'P' being used for a clan containing families of more than one of the catalytic types serine, threonine and cysteine). Some families cannot yet be assigned to clans, and when a formal assignment is required, such a family is described as belonging to clan A-, C-, M-, N-, S-, T- or U-, according to the catalytic type. Some clans are divided into subclans because there is evidence of a very ancient divergence within the clan, for example MA(E), the gluzincins, and MA(M), the metzincins. Peptidase families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; N, asparagine; S, serine; T, threonine; and U, unknown. The serine, threonine and cysteine peptidases utilise the amino acid as a nucleophile and form an acyl intermediate - these peptidases can also readily act as transferases. In the case of aspartic, glutamic and metallopeptidases, the nucleophile is an activated water molecule. In the case of the asparagine endopeptidases, the nucleophile is asparagine and all are self-processing endopeptidases. In many instances the structural protein fold that characterises the clan or family may have lost its catalytic activity, yet retain its function in protein recognition and binding. Metalloproteases are the most diverse of the four main types of protease, with more than 50 families identified to date. In these enzymes, a divalent cation, usually zinc, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. The known metal ligands are His, Glu, Asp or Lys and at least one other residue is required for catalysis, which may play an electrophillic role. Of the known metalloproteases, around half contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site []. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases []. This group of metallopeptidases belong to MEROPS peptidase family M32 (carboxypeptidase Taq family, clan MA(E)). The predicted active site residues for members of this family and thermolysin, the type example for clan MA, occur in the motif HEXXH. Carboxypeptidase Taq is a zinc-containing thermostable metallopeptidase. It was originally discovered and purified from Thermus aquaticus; optimal enzymatic activity occurs at 80 celcius. Although very little is known about this enzyme, it is thought either to be associated with a membrane or to be particle bound.; GO: 0004181 metallocarboxypeptidase activity, 0006508 proteolysis; PDB: 1K9X_A 1KA4_A 1KA2_A 3DWC_A 1WGZ_A 3HQ2_A 3HOA_B.

InhA of Bacillus thuringiensis (an entomopathogenic bacterium) specifically cleaves antibacterial peptides produced by insect hosts []. B. thuringiensis is highly resistant to the insect immune system due to its production of two factors, inhibitor A (InhA or InA) and inhibitor B (InhB or InB), which selectively block the humoral defence system developed by insects against Escherichia coli and Bacillus cereus []. B. thuringiensis is especially resistant to cecropins and attacins, which are the main classes of inducible antibacterial peptides in various lepidopterans and dipterans [], []. InhA has been shown to specifically hydrolyze cecropins and attacins in the immune hemolymph of Hyalophora cecropia (Cecropia moth) in vitro []. However, it has been suggested that the role of InhA in resistance to the humoral defence system is not consistent with the time course of InhA production []. B. thuringiensis has two proteins belonging to this group (InhA and InhA2), and it has been shown that InhA2 has a vital role in virulence when the host is infected via the oral route []. The B. cereus member has been found as an exosporium component from endospores []. B. thuringiensis InhA is induced at the onset of sporulation and is regulated by Spo0A and AbrB []. Vibrio cholerae PrtV is thought to be encoded in the pathogenicity island []. However, PrtV mutants did not exhibit a reduced virulence phenotype, and thus PrtV is not an indispensable virulence factor []. Annotation note: due to the presence of PKD repeats in some of the members of this group (e.g., V. cholerae VCA0223), spurious similarity hits may appear (involving unrelated proteins), which may lead to the erroneous transfer of functional annotations and protein names. Also, please note that related Bacillus subtilis Bacillopeptidase F (Bpr or Bpf) contains two different protease domains: N-terminal IPR000209 from INTERPRO (peptidase S8, subtilase, a subtilisin-like serine protease) and this C-terminal domain (peptidase M6), which may also complicate annotation.; GO: 0008233 peptidase activity, 0006508 proteolysis

In the amastigote form, the parasite lives in lysosomes of host macrophages, producing a form of the protease that has an acidic pH optimum [].

>PF08325 WLM: WLM domain; InterPro: IPR013536 The WLM (WSS1-like metalloprotease) domain is a globular domain related to the zincin-like superfamily of Zn-dependent peptidase. Since the WLM domain contains all known active site residues of zincins, it is predicted to be a catalytically active peptidase domain. The WLM domain is a eukaryotic domain represented in plants, fungi, Plasmodium, and kinetoplastids. By contrast, it is absent in animals, Cryptosporidium, and Microsporidia, suggesting that it has been lost on multiple occasions during the evolution of eukaryotes. The WLM domain is found either in stand-alone form or in association with other domains such as the RanBP2 zinc finger , the ubiquitin domain, or the PUB/PUG domain. This domain could function as a specific de-SUMOylating domain of distinct protein complexes in the nucleus and the cytoplasm []. It has been suggested to form a segregated alpha/beta structure with eight helices and five strands. Proteins containign this domain include yeast WSS1 (a weak suppressor of the Ub-related protein SMT3), and various putative metalloproteases from plant and fungal species.
