IntEnz Enzyme Nomenclature


Accepted name:
angiotensin-converting enzyme 2
Other names:
angiotensin converting enzyme 2
angiotensin converting enzyme-2
Systematic name:



A transmembrane glycoprotein with an extracellular catalytic domain. Angiotensin-converting enzyme 2 functions as a carboxypeptidase, cleaving a single C-terminal residue from a distinct range of substrates [2]. Catalytic efficiency is 400-fold higher with angiotensin II (1-8) as a substrate than with angiotensin I (1-10). Angiotensin-converting enzyme 2 also efficiently hydrolyzes des-Arg9-bradykinin, but it does not hydrolyze bradykinin [1]. In peptidase family M2.
