Enzyme Commission Primary Name: pro-opiomelanocortin converting enzyme
Enzyme Commission Synonyms: prohormone converting enzyme, pro-opiomelanocortin-converting enzyme, proopiomelanocortin proteinase, PCE
Enzyme Commission Summary:
This enzyme catalyzes cleavage of certain prohormones, such as proopiomelanocortin, at paired basic residues, generating several peptides, some of which are functional hormones. A 70 kDa membrane-bound enzyme has been isolated from cattle pituitary secretory vesicle.
