Crystal Structure of the Nerve Agent Degrading Organophosphate Anhydrolase/Prolidase in Complex with Inhibitors

Template:ABSTRACT PUBMED 20000741

Function

[PEPQ_ALTSX] Splits dipeptides with a prolyl or hydroxyprolyl residue in the C-terminal position and a nonpolar amino acid at the N-terminal position. Also catalyzes the hydrolysis of toxic organophosphorus cholinesterase-inhibiting compounds including insecticide paraoxon and nerve gases such as diisopropylfluorophosphate (DFP), O-isopropyl methylphosphonofluoridate (sarin), O-pinacolyl methylphosphonofluoridate (soman), and O-cyclohexyl methylphosphonofluoridate.[1] [2] [3] [4]

About this Structure

3l24 is a 3 chain structure with sequence from Alteromonas sp.. Full crystallographic information is available from OCA.
