The N-terminal pGlu protects these proteins from proteolysis by other proteases until the pGlu is removed by a PGP. PGPs are cysteine proteases with a Cys-His-Glu/Asp catalytic triad. Type I PGPs are found in a wide variety of prokaryotes and eukaryotes. It is not clear whether the functional form is a monomer, a homodimer, or a homotetramer. Length = 194 |

; InterPro: IPR000816 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. Cysteine peptidases have characteristic molecular topologies, which can be seen not only in their three-dimensional structures, but commonly also in the two-dimensional structures. These are peptidases in which the nucleophile is the sulphydryl group of a cysteine residue. Cysteine proteases are divided into clans (proteins which are evolutionary related), and further sub-divided into families, on the basis of the architecture of their catalytic dyad or triad []. This group of cysteine peptidases belong to MEROPS peptidase family C15 (pyroglutamyl peptidase I, clan CF). The type example being pyroglutamyl peptidase I of Bacillus amyloliquefaciens. Pyroglutamyl/pyrrolidone carboxyl peptidase (Pcp or PYRase) is an exopeptidase that hydrolytically removes the pGlu from pGlu-peptides or pGlu-proteins [, ]. PYRase has been found in prokaryotes and eukaryotes where at least two different classes have been characterised: the first containing bacterial and animal type I PYRases, and the second containing animal type II and serum PYRases. Type I and bacterial PYRases are soluble enzymes, while type II PYRases are membrane-bound. The primary application of PYRase has been its utilisation for protein or peptide sequencing, and bacterial diagnosis []. The conserved residues Cys-144 and His-168 have been identified by inhibition and mutagenesis studies [, ].; GO: 0006508 proteolysis; PDB: 1A2Z_A 1IU8_A 3RNZ_A 3RO0_D 1AUG_D 2EBJ_A 3LAC_A 1X12_B 1Z8X_B 1X10_C .... |
