Yes, angiotensin II (AII) is a polypeptide. It results from the conversion of angiotensin I through the activity of angiotensin I-converting enzyme (ACE). In fact, ACE is a dipeptidase with at least ten identified substrate such as bradykinin, substance P, GnRH etc. ACE cleaves the Phe-His bond of AI, hus setting free the C-terminal His-Leu, resulting in the active form, AII (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe). AII is a vasoconstrictor and serves numerous functions, among them blood pressure regulation, organogenesis, male fertility, ovulation and others.
