Study on the Degradation Effect of Three Organophosphorus Hydrolase Mutant on Sarin [PDF]

open access: yesE3S Web of Conferences, 2021
Organophosphorus hydrolase can effectively degrade organic phosphorus compounds such as sarin. In this study, we constructed a recombinant Bacillus subtilis mutant expressing organophosphorus hydrolase, measured the effect of the mutant on the ...

Neurotoxicity in Preclinical Models of Occupational Exposure to Organophosphorus Compounds. [PDF]

open access: yesFront Neurosci, 2016
Organophosphorus (OPs) compounds are widely used as insecticides, plasticizers, and fuel additives. These compounds potently inhibit acetylcholinesterase (AChE), the enzyme that inactivates acetylcholine at neuronal synapses, and acute exposure to high ...

New Enzymatic Targets for Organophosphorus Compounds

open access: yesВестник войск РХБ защиты, 2023
It is known that several decarboxylases (aromatic amino acid decarboxylase (AAD), histidine decarboxylase (HD) and glutamate decarboxylase (GD) with different molecular weights catalyze the most important reactions of neurotransmitter and neuromodulator ...

New Trends in Biosensors for Organophosphorus Pesticides

open access: yesSensors, 2001
Biosensors are sensitive and can be used as disposable sensors for environmental control. These biosensors are based either on inhibition of acyl cholinesterases acetylcholinesterase or butyrylcholinesterase) by organophosphorus compounds or on ...

New Cinchona Oximes Evaluated as Reactivators of Acetylcholinesterase and Butyrylcholinesterase Inhibited by Organophosphorus Compounds. [PDF]

open access: yesMolecules, 2017
For the last six decades, researchers have been focused on finding efficient reactivators of organophosphorus compound (OP)-inhibited acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). In this study, we have focused our research on a new oxime
