Pyroglutamyl-peptidase I (EC 3.4.19.3, 5-oxoprolyl-peptidase, pyrase, 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.[1][2][3][4] 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
This cysteine peptidase is isolated from bacteria, plants and animals.
