Hydrolysis of VX and related compounds by organophosphorus hydrolase. Final report, Februray-December 1993

Organophosphorus Hydrolase (OPH) is a fully characterized and cloned enzyme, derived from Pseudomonas diminuta, consisting of 365 amino acids with a total molecular weight of 38,0(X). The enzyme has a leader sequence of 29 amino acids which has been removed in the construction used in this study. OPH was evaluated for its effectiveness in catalyzing the S-(2-diisopwpylaminoethyl) methylphosphonothioate (VX) and its analogs.
