Chemical modification of Cys231 by mercuric chloride produces initially a quasinative state of Torpedo acetylcholinesterase which, at room temperature, undergoes spontaneous transition to a molten globule state with a half-life of 1-2 hr.

Rosy barb (Puntius conchonius) were exposed to 181 micrograms/l mercuric chloride for 48 h and the activity of acid and alkaline phosphatases (AcP and AIP), aspartate aminotransferase (AAT), alanine aminotransferase (AIAT), lactic dehydrogenase (LDH), and acetylcholinesterase (AchE) were measured in vivo in several organs. 2.

Our results show that when a free sensitive sulfhydryl group is present in the enzyme, as in Torpedo californica acetylcholinesterase, inhibition is irreversible and follows pseudo-first-order kinetics that are completed within 1 h in the micromolar range.

The present study compares the effects of Se as sodium selenite (Na2SeO3) and Hg as mercuric chloride (HgCl2) separately and in combination.
The following biochemical alterations occurred in response to Hg treatment: protein content (brain and liver), acetylcholinesterase (AChE) (brain and serum), acid and alkaline (AcP and AlP) phosphatases (plasma and liver) and glutathione S-transferase (GST) (plasma and liver) activities were significantly (P <0.05) decreased, while lactate dehydrogenase (LDH) (plasma, brain and liver), aspartate and alanine aminotransferase (AST, ALT) (serum and liver) activities were significantly increased.

A variety of changes occur in the rabbit under metal stress which include the appearance of the acute phase protein, C-reactive protein in the serum and significant reduction in the serum titres of albumin and acetylcholinesterase.

Aquat Toxicol. 2007 Aug 1;83(4):272-83. Epub 2007 May 13.


In addition, as it is well-known that the inhibition of acetylcholinesterase activity represents a specific biomarker of exposure to OP and carbamate pesticides in higher organisms, initially the presence of cholinesterase (ChE) activity was detected in E. crassus, using cytochemical, spectrophotometric and electrophoretic methods.
