Anti-cholinesterase insecticides constitute a major portion of modern synthetic pesticides and the assessment of cholinesterase (ChE) inhibition is widely used as a specific biomarker for evaluating the exposure of non-target organisms to these pollutants. However, most studies on this biomarker
Spontaneous recovery of cholinesterases after organophosphate intoxication: effect of environmental temperature.
P Honkakoski et al.
Bulletin of environmental contamination and toxicology, 40(3), 358-364 (1988-03-01)
The main purpose of this study was to describe the kinetic properties of the cholinesterase (ChE) enzyme present in the eyes of the prawn Palaemon serratus, an abundant, ecological and commercially relevant species of European coastal environments. The obtained results
Acetylcholinesterases (AChEs) have been estimated in the infective juveniles (IJs) of eight different strains of heterorhabditid nematodes. The enzyme content ranged from 45.6 to 421.3 units/10(5) IJs with specific activity 34.0 to 82.6 units/mg protein. The isoenzyme patterns revealed the

Acetylcholinesterase (AChE, EC 3.1.1.7) purified from the lesser grain borer (Rhyzopertha dominica) was significantly inhibited by higher concentrations of the substrates acetylthiocholine (ATC), acetyl-(beta-methyl) thiocholine (A beta MTC) and propionylthiocholine (PTC). 2. The efficiency of AChE for hydrolyzing different substrates
