Turnover number of acetyl-cholinesterase.
The turnover number of acetylcholinesterase is of special interest because the enzyme is thought to be one of the fastest enzymes and because a high speed is a prerequisite for the role of the enzyme in nervous function (1). The earliest value of the turnover number was given by Rothenberg and Nachman sohn (2) in terms of the molecular weight for enzyme obtained from electric eel. The molecular...
متن کاملprotective effects of selenium and zinc on the brain acetyl cholinesterase activity in lead intoxified rat
lead is a common toxic agent which impairs various organs functions of the body. the basis of this toxicity is believed to be the negative influence on enzymatic system of cells. in the past few years, increasing consideration has been given to interactions occurring between lead and some essential metals including se and zn. based on the finding that some trace elements could reverse the toxic...

متن کاملThe mode of recovery of cholinesterase activity in vivo after organophosphorus poisoning. 2. Brain cholinesterase.
Previous investigators (Frawley, Hagan & Fitzhugh, 1952; Davison, 1955; Kewitz & Nachmansohn, 1957) have observed that the rate of recovery in vivo of inhibited brain true cholinesterase depended on which inhibitor was used. With diiwopropyl phosphorofluoridate (Frawley et al. 1952; Davison, 1955; Kewitz & Nachmansobn, 1957) recovery was slow, whereas with tetraethyl pyrophosphate (Davison, 195...
متن کاملAcrylonitrile has Distinct Hormetic Effects on Acetyl-Cholinesterase Activity in Mouse Brain and Blood that are Modulated by Ethanol.
Acrylonitrile(AN) is a neurotoxin both in animals and humans, but its effects on acetylcholinesterase (AChE) activity remain controversial. This study aimed to determine the dose-response effects of AN on AChE activity and the modulatory role of ethanol pre-treatment. A total of 144 Kunming mice were randomly divided into 18 groups: nine groups received 5% ethanol in their drinking water, and t...
