Related to angiotensin I: angiotensin II
A decapeptide of slightly variable sequence, depending on the animal source, formed from the tetradecapeptide angiotensinogen by the removal of four amino acid residues, a reaction catalyzed by renin; a peptidase cleaves off a dipeptide (histidylleucine) to yield angiotensin II, the physiologically active form.
