Crystal structure of ANCE in complex with bradykinin potentiating peptide b

Released:

Function and Biology Details

Reaction catalysed:
Release of a C-terminal dipeptide, oligopeptide-|-Xaa-Yaa, when Xaa is not Pro, and Yaa is neither Asp nor Glu. Thus, conversion of angiotensin I to angiotensin II, with increase in vasoconstrictor activity, but no action on angiotensin II.
