| + | [https://www.uniprot.org/uniprot/PEPQ_ECOLI PEPQ_ECOLI] Splits dipeptides with a prolyl residue in the C-terminal position and a polar or nonpolar amino acid at the N-terminal position. With much lower efficiency, also catalyzes the stereoselective hydrolysis of a wide variety of organophosphate triesters and organophosphonate diesters. Is able to hydrolyze the organophosphorus insecticide paraoxon and the p-nitrophenyl analogs of the nerve agents GB (sarin), GD (soman), GF, Vx and rVX.<ref>PMID:15313226</ref> | ||
