Abstract
Previously (1), I have reported on the kinetical property of benzoylcholinesterase (BzChE) and on the influence of anti-chol ineste rase (anti-ChE) on BzChE using guinea pig liver, and found that BzChE is an entirely different enzyme from the nonspecific ChE enzymologically.
During the course of the previous experiments I have found that propylene glycol (P.G.), ethylene glycol (E.G.) and polyethylene glycol (PE. G.) activated nonspecific ChE, but inhibited BzChE.
This paper deals with the mechanism of their action and the enzymological characteristics of BzChE.
