The present work describes a new method to sense cholinesterase-catalyzed hydrolysis of acetylcholine (ACh) through a luminescence response of the hexarhenium cluster complex [{Re6S8}(OH)6](4-). A proton released from acetylcholinesterase (AChE)- or butyrylcholinesterase (BuChE)-catalyzed hydrolysis of ACh results in time-resolved...

Cholinesterases are enzymes able to hydrolyze the neurotransmitter acetylcholine and thus to terminate transmission. Once the enzymes are inhibited, excitotoxicity can appear in the adjacent cells. It is well known that oxidative stress is involved in the toxicity of...

2-Isopropyl-4-dimethylamino-5-methylphenyl-1-piperidine carboxylate methyl chloride (AMO-1618) inhibits the activity of a cholinesterase isolated from mung bean (Phaseolus aureus) roots at concentrations comparable to those which retard growth and inhibit development of secondary roots of bean seedlings. Fifty per cent inhibition...

Cholinesterases from plant tissue: v. Cholinesterase is not pectin esterase.

PMID: 16658976
Plant Physiol. 1974 Nov;54(5):797-8. doi: 10.1104/pp.54.5.797.

Several properties of the cholinesterase from Phaseolus aureus Roxb. and of pectin (methyl) esterases from both Phaseolus aureus and Lycopersicon esculentum (L.) Mill. are contrasted. Cholinesterase activity is inhibited by all of the concentrations of NaCl tested, from 0.05...

The screen-printed four-electrode system was used as the amperometric transducer for determination of phenols and pesticides using immobilised tyrosinase, peroxidase, acetylcholinesterase and butyrylcholinesterase. Acetylthiocholine chloride was chosen as substrate for cholinesterases to measure inhibition by pesticides, hydrogen peroxide served...

Cholinesterases from Plant Tissues: III. Distribution and Subcellular Localization in Phaseolus aureus Roxb.

PMID: 16658783
Plant Physiol. 1974 May;53(5):752-8. doi: 10.1104/pp.53.5.752.

The distribution and localization of cholinesterase in Phaseolus aureus, Glycine max, and Pisum sativum is described. The enzyme is present in roots, leaves, stems, root callus tissue, root cells suspension cultures, and root nodules. Cholinesterase in roots is found...

Microscopic localization of cholinesterases in the nervous systems of the lobsters, Panulirus argus and Homarus americanus.

Using acetylthiocholine as substrate, microscopically localizable cholinesterase (ChE) activity is demonstrated in neural and glial elements of central and peripheral nervous systems of the lobsters, Panulirus argus and Homarus americanus. Moderate to very intense ChE activity occurs in all...
