Protein

Angiotensin-converting enzyme

Gene

ACE

Organism
Theromyzon tessulatum (Duck leech)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Catalytic activityi

Release of a C-terminal dipeptide, oligopeptide-|-Xaa-Yaa, when Xaa is not Pro, and Yaa is neither Asp nor Glu. Thus, conversion of angiotensin I to angiotensin II, with increase in vasoconstrictor activity, but no action on angiotensin II.1 Publication

Cofactori

Binds 1 zinc ion per subunit.By similarity
Chloride.By similarity

Enzyme regulationi

Activated by chloride. Inhibited by captopril and lisinopril, and to a lesser extent by delaprilat.1 Publication
