angiotensin-converting enzyme (ACE),

a glycoprotein (dipeptidyl carboxypeptidase) that catalyzes the conversion of angiotensin I to angiotensin II by splitting two terminal amino acids. ACE-inhibiting agents are used for controlling hypertension and for protecting the kidneys in diabetes mellitus.

angiotensin-converting enzyme

A key enzyme in the RAA system, which converts the inactive decapeptide angiotensin I to the octapeptide, angiotensin II, a potent vasoconstrictor that also stimulates aldosterone secretion; ACE is also involved in metabolizing bradykinin Ref range 18–67 U/L, > age 20; those < 20 have higher levels; ACE is ↑ in sarcoidosis, Gaucher disease, leprosy, histoplasmosis, cirrhosis, asbestosis, berylliosis, DM, Hodgkin's disease, hyperthyroidism, amyloidosis, PBC, idiopathic pulmonary fibrosis, PE, scleroderma, silicosis, TB; ACE ↓ in response to prednisone therapy for sarcoidosis.
