Angiotensin-converting enzyme 2 (ACE2) is a monocarboxypeptidase that metabolizes several peptides, including the degradation of angiotensin (Ang) II, a peptide with vasoconstrictive/proliferative effects, to generate Ang 1-7, which exerts vasodilatory/antiproliferative actions by acting through its receptor Mas. ACE2 is a multifunctional enzyme, and its actions on other vasoactive peptides, including ...
