This human Angiotensin I (Ang I) sequence also corresponds to horse, sheep, pig, and rat Ang I. Ang I is cleaved to Ang II by the angiotensin-converting enzyme (ACE). There is also evidence for non-angiotensin-converting enzyme-dependent conversion of Ang I to Ang II. Human chymase efficiently converts the 10-mer Ang I to the 8-mer hormone Ang II by splitting the Phe8-His9 bond in Ang I.
