We describe here the purification and identification of a previously unrecognized target for organophosphorus compounds. The target, acylpeptide hydrolase, was isolated as a tritiated-diisopropylfluorophosphate-reactive protein from porcine brain and purified to homogeneity using a combination of ion-exchange and gel-filtration chromatography. Biochemical characterization and internal sequence ...
