title: Genetically defined lysosomal acetylesterase EC 3.1.1.6 in the cauda epididymidis of mouse, rat, and man.
abstract: After inhibition by bis-p-nitrophenyl phosphate and subsequent staining for esterase using naphthol AS-D acetate as the substrate, a strong lysosomal esterase was demonstrated in the cauda epididymidis of mouse, rat, and man. Owing to its behaviour towards the classifying inhibitors eserine, diisopropyl fluorophosphate, bis-p-nitrophenyl phosphate, and p-chloromercuriphenylsulphonate, this lysosomal esterase was shown to be an acetylesterase (EC 3.1.1.6). Control experiments involving isoelectric focusing revealed that this acetylesterase was identical with the genetically defined homologues ES-17, ES-6, and ES-A4 in mouse, rat, and man, respectively.
