It can be used to distinguish certain Streptococcal organisms.[1]
Other names are 5-oxoprolyl-peptidase, pyrase, pyrrolidonyl arylamidase, pyroglutamate aminopeptidase, pyroglutamyl aminopeptidase, L-pyroglutamyl peptide hydrolase, pyrrolidone-carboxyl peptidase, pyrrolidone-carboxylate peptidase, pyrrolidonyl peptidase, L-pyrrolidonecarboxylate peptidase, pyroglutamidase, pyrrolidonecarboxylyl peptidase) is an enzyme.[2][3][4][5] This enzyme catalyses the following chemical reaction
- Release of an N-terminal pyroglutamyl group from a polypeptide, the second amino acid generally not being Pro
