Pseudomonas sedolisin (serine-carboxyl proteinase) complexed with two molecules of pseudo-iodotyrostatin


Function and Biology Details

Reaction catalysed:
Hydrolysis of the B chain of insulin at 13-Glu-|-Ala-14, 15-Leu-|-Tyr-16 and 25-Phe-|-Tyr-26 and angiotensin I at 4-Tyr-|-Ile-5. A good synthetic substrate is Lys-Pro-Ile-Glu-Phe-|-Phe(NO(2))-Arg-Leu.
