Acetylcholinesterase definition, an enzyme that hydrolyzes the neurotransmitter acetylcholine: its action is blocked by nerve gases and certain drugs. Die Acetylcholinesterase ist eines der schnellsten Enzyme überhaupt (diffusionskontrolliert, siehe Enzymkinetik und Diffusion). Die Acetylcholinesterase (AChE) ist ein Enzym aus der Gruppe der Cholinesterasen, welches spezifisch den Neurotransmitter Acetylcholin (ACh) in Essigsäure (das Acetat wird nach der Spaltung rasch protoniert) und Cholin hydrolysiert.. Wirkung. Jump to: navigation, search. Die Acetylcholinesterase ist ein wichtiges Enzym der mit dem Neurotransmitter Acetylcholin arbeitenden Synapsen. Die Acetylcholinesterase zerlegt den Neurotransmitter Acetylcholin im synaptischen Spalt in seine beiden Grundbausteine Essigsäure ("Acetyl-") und Cholin.Diese Funktion ist äußerst wichtig für die Funktion der Synapse. Acetylcholinesterase is a type-B carboxylesterase enzyme located primarily in the synaptic cleft with a smaller concentration in the extrajunctional area. For myasthenia gravis treatment, acetylcholinesterase inhibitors are the first treatment used. What is Acetylcholinesterase?
