Accepted name: angiotensin-converting enzyme 2
Reaction: angiotensin II + H2O = angiotensin-(1–7) + L-phenylalanine
Other name(s): ACE-2; ACE2; hACE2; angiotensin converting enzyme 2; angiotensin converting enzyme-2; Tmem27
Comments: 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 hydrolyses des-Arg9-bradykinin, but it does not hydrolyse bradykinin [1]. In peptidase family M2.
