The cell wall also functions as a surface organelle that allows Gram-positive pathogens to interact with their environment, in particular the tissues of the infected host. All of these functions require that surface proteins and enzymes be properly targeted to the cell wall envelope. Two basic mechanisms, cell wall sorting and targeting, have been identified. Cell well sorting is the covalent attachment of surface proteins to the peptidoglycan via a C-terminal sorting signal that contains a consensus LPXTG sequence. More than 100 proteins that possess cell wall-sorting signals, including the M proteins of Streptococcus pyogenes, protein A of Staphylococcus aureus, and several internalins of Listeria monocytogenes, have been identified. Cell wall targeting involves the noncovalent attachment of proteins to the cell surface via specialised binding domains. Several of these wall-binding domains appear to interact with secondary wall polymers that are associated with the peptidoglycan, for example teichoic acids and polysaccharides. Proteins that are targeted to the cell surface include muralytic enzymes such as autolysins, lysostaphin, and phage lytic enzymes. Other examples for targeted proteins are the surface S-layer proteins of bacilli and clostridia, as well as virulence factors required for the pathogenesis of L. monocytogenes (internalin B) and Streptococcus pneumoniae (PspA) infections .

It has been shown that a block in polar cytokinesis in Bacillus subtilis is mediated partly by transcription of spoIID, spoIIM and spoIIP. This inhibition of polar division is involved in the locking in of asymmetry after the formation of a polar septum during sporulation . SpoIIP is one of the three genes (spoIID, spoIIM and spoIIP, , , ), under the control of sigma E, that have been shown to be essential for the engulfment of the forespore by the mother cell. Their products are involved in degradation of the septal peptidoglycan and mutations in spoIID, spoIIM or spoIIP block sporulation at morphological stage II, prior to the stage of engulfment. These three genes are absolutely conserved (sometimes even duplicated) in all endospore formers .

PGM (5.4.2.2 from EC) converts D-glucose 1-phosphate into D-glucose 6-phosphate, and participates in both the breakdown and synthesis of glucose . PGM/PMM (5.4.2.2 from EC; 5.4.2.8 from EC) are primarily bacterial enzymes that use either glucose or mannose as substrate, participating in the biosynthesis of a variety of carbohydrates such as lipopolysaccharides and alginate , . Both PNGM (5.4.2.3 from EC) and PAGM (5.4.2.10 from EC) are involved in the biosynthesis of UDP-N-acetylglucosamine , . Despite differences in substrate specificity, these enzymes share a similar catalytic mechanism, converting 1-phospho-sugars to 6-phospho-sugars via a biphosphorylated 1,6-phospho-sugar. The active enzyme is phosphorylated at a conserved serine residue and binds one magnesium ion; residues around the active site serine are well conserved among family members. The reaction mechanism involves phosphoryl transfer from the phosphoserine to the substrate to create a biophosphorylated sugar, followed by a phosphoryl transfer from the substrate back to the enzyme . The structures of PGM and PGM/PMM have been determined, and were found to be very similar in topology. These enzymes are both composed of four domains and a large central active site cleft, where each domain contains residues essential for catalysis and/or substrate recognition. Domain I contains the catalytic phosphoserine, domain II contains a metal-binding loop to coordinate the magnesium ion, domain III contains the sugar-binding loop that recognises the two different binding orientations of the 1- and 6-phospho-sugars, and domain IV contains a phosphate-binding site required for orienting the incoming phospho-sugar substrate. This entry represents domain II found in alpha-D-phosphohexomutase enzymes.

Clans are groups of families for which there is evidence of common ancestry. 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-, 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. Families are grouped by their catalytic type, the first character representing the catalytic type: A, aspartic; C, cysteine; G, glutamic acid; M, metallo; 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. Aspartic endopeptidases 3.4.23. from EC of vertebrate, fungal and retroviral origin have been characterised . More recently, aspartic endopeptidases associated with the processing of bacterial type 4 prepilin and archaean preflagellin have been described , . Structurally, aspartic endopeptidases are bilobal enzymes, each lobe contributing a catalytic Asp residue, with an extended active site cleft localized between the two lobes of the molecule. One lobe has probably evolved from the other through a gene duplication event in the distant past. In modern-day enzymes, although the three-dimensional structures are very similar, the amino acid sequences are more divergent, except for the catalytic site motif, which is very conserved. The presence and position of disulphide bridges are other conserved features of aspartic peptidases. All or most aspartate peptidases are endopeptidases. These enzymes have been assigned into clans (proteins which are evolutionary related), and further sub-divided into families, largely on the basis of their tertiary structure. Metalloproteases are the most diverse of the four main types of protease, with more than 30 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 . The large subunit of [NiFe]-hydrogenase, as well as other nickel metalloenzymes, is synthesized as a precursor devoid of the metalloenzyme active site. This precursor undergoes a complex post-translational maturation process that requires a number of accessory proteins , , . At one step of this process, after nickel incorporation, each hydrogenase isoenzyme is processed by proteolytic cleavage at the C-terminal end by the corresponding hydrogenase maturation endopeptidase . For example, Escherichia coli HycI is involved in processing of pre-HycE (the large subunit of hydrogenase 3) , ; HybD is involved in processing of pre-HybC (the large subunit of hydrogenase 2) ; and HyaD is assumed to be involved in processing of the large subunit of hydrogenase 1. This group represents metallopeptidases of the MEROPS peptidase family A31 (HybD endopeptidase family, clan AE). The cleavage site is after a His or an Arg, liberating a short peptide , . This cleavage occurs only in the presence of nickel, and the endopeptidase probably uses the metal in the large subunit of [NiFe]-hydrogenases as a recognition motif . There is no direct evidence for the active site or substrate-binding site, but there are predictions based on an available structure . Nomenclature note: the following names are used in different organisms for members of this group: HycI, HybD, HyaD, HoxM, HoxW, HupD, HynC, HupM, VhoD, VhtD . Gene/protein names are sometimes used interchangeably to designate various "hydrogenase cluster" proteins unrelated to each other in various organisms. For example, the following names are used for members of this group, but also for unrelated proteins: HupD is used in Azotobacter chroococcum and Anabaena sp. to designate an unrelated hydrogenase maturation factor; HydD is used to designate hydrogenase structural genes in Thermococcus litoralis, Pyrococcus abyssi, and other species.; GO: 0008047 enzyme activator activity, 0008233 peptidase activity; PDB: 1cfz_B 2e85_A 2i8l_A.
