概述

Butyrl Cholinesterase catalyzes the hydrolysis of a number of choline esters according to the following reaction: ^Acylcholine + H2O → choline + acid ^It is a tetrameric glycoprotein with four subunits of equal size, each having a molecular weight of 110 kDa. Butyryl cholinesterase hydrolyzes butyrylcholine four times more rapidly than acetylcholine. Unlike acetyl cholinesterase, it does not hydrolyze D-≥-methyl acetylcholine. It is inhibited by 10-5 M physostigmine, numerous organophosphate esters, the carbamate derivates and quaternary ammonium salts
