애플리케이션
Butyrylcholinesterase (BChE) from equine serum has been used:
- to determine the inhibitory concentration of bupivacaine on butyrylcholinesterase
- in acetylcholinesterase (AChE)/BChE activity assay to determine the inhibitory activity of benzothiazole-piperazine compounds
Selective inhibition of BChE activity can be used in the detection of organophosphates. Its use in the treatment of organophosphate toxicity shows promise. There is a correlation between the level of BChE in human blood and degree of protection against potentially toxic nerve agents. There has also been interest in the roles of cholinesterases with regard to Alzheimer′s disease. Investigations into selective inhibitors may provide a clearer picture of the physiological role of BChE in both healthy and diseased individuals. The enzyme has been used to test bupivacaine as an inhibitor of butyrylcholinesterase during acetylcholinesterase assay using cerebrospinal fluid.
생화학적/생리학적 작용
Butyrylcholinesterase (BChE) is a serine hydrolase that is structurally similar to acetylcholinesterase (AChE), but differs in substrate specificities and inhibitor sensitivities. BChE can, unlike AChE, efficiently hydrolyze larger esters of choline such as butyrylcholine and benzoylcholine. The enzyme is a tetrameric glycoprotein with four equal subunits (110 kDa each). The enzyme is activated by Ca2+ and Mg2+ and the activity is constant over the pH range 6.0-8.0. It is inhibited by Betaine, nicotine, organophosphates, carbamates.
단위 정의
One unit will hydrolyze 1.0 μmole of butyrylcholine to choline and butyrate per min at pH 8.0 at 37 °C. The activity obtained using butyrylcholine as substrate is ~2.5 times that obtained using acetylcholine.

Most test systems for acetylcholinesterase activity (E.C.3.1.1.7.) are using toxic inhibitors (BW284c51 and iso-OMPA) to distinguish the enzyme from butyrylcholinesterase (E.C.3.1.1.8.) which occurs simultaneously in the cerebrospinal fluid. Applying Ellman's colorimetric method, we were looking for a non-toxic inhibitor to
