Pitrilysin.
based on mapping to UniProt P05458
Preferential cleavage of 16-Tyr-|-Leu-17 and 25-Phe-|-Tyr-26 bonds of oxidized insulin B chain. Also acts on other substrates of Mw less than 7 kDa such as insulin and glucagon.
-!- From the periplasmic space of Escherichia coli. -!- Inhibited by EDTA and 1,10-phenanthroline; not thiol dependent. -!- Belongs to peptidase family M16. -!- Formerly EC 3.4.99.44.
