peptidyl-dipeptidase A

peptidyl-dipeptidase A
pep·ti·dyl-di·pep·ti·dase A (pepґtĭ-dəl di-pepґtĭ-dās) [EC 3.4.15.1] an enzyme of the hydrolase class that catalyzes the cleavage of a dipeptide from the C-terminal end of an oligopeptide; it is a zinc protein found on the luminal surface of vascular endothelial cells in the lungs and other tissues. When catalyzing the cleavage of angiotensin I to form the activated angiotensin II, it is also called angiotensin-converting enzyme; when catalyzing the cleavage and inactivation of kinins, it is also called kininase II. Called also dipeptidyl carboxypeptidase I.
