Protein

Angiotensin-converting enzyme

Gene

ACE

Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Converts angiotensin I to angiotensin II by release of the terminal His-Leu, this results in an increase of the vasoconstrictor activity of angiotensin. Also able to inactivate bradykinin, a potent vasodilator. Has also a glycosidase activity which releases GPI-anchored proteins from the membrane by cleaving the mannose linkage in the GPI moiety (By similarity).By similarity

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.

Cofactori

Protein has several cofactor binding sites:
  • Zn2+By similarityNote: Binds 2 Zn2+ ions per subunit. Isoform Testis-specific only binds 1 Zn2+ ion per subunit.By similarity
  • chlorideBy similarityNote: Binds 3 chloride ions per subunit.By similarity

Activity regulationi

Strongly activated by chloride. Specifically inhibited by lisinopril.1 Publication
