An enzyme that breaks down the neurotransmitter acetylcholine at the synaptic cleft (the space between two nerve cells) so the next nerve impulse can be transmitted across the synaptic gap. Pesticides of the organophosphate and carbamate types act to paralyze and kill insects by inhibiting their acetylcholinesterase. Abbreviated AChE.

(ua-set´´l-ko´´lu1-nes´tue-r=as) An enzyme in the membrane of postsynaptic cells that catalyzes the conversion of ACh into choline and acetic acid. This enzymatic reaction inactivates the neurotransmitter. Achilles tendon

noun. a compound that divides acetylcholine into choline and acetic acid, subsequently turning off the neurotransmitter after its discharge at a synaptic intersection.

Acetylcholinesterase (AChE) is an enzyme that breaks down and deactivates acetylcholine (ACh) after it is released by terminal buttons. AChE is located naturally in the postsynaptic membrane and break [..]

An enzyme that catalyzes the Hydrolysis of Acetylcholine to Choline and acetate. In the CNS, this enzyme plays a Role in the function of peripheral Neuromuscular Junctions. EC 3.1.1.7.

An enzyme that catalyzes the hydrolysis of ACETYLCHOLINE to CHOLINE and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7.

<enzyme> <neurology, physiology> An enzyme that breaks down unused acetylcholine in the synaptic cleft (the space between neurones), this enzyme is necessary to restore the synaptic cleft so it is ready to transmit the next nerve impulse. (06 May 1997)

An enzyme present in various tissues, including muscle and red cells, that breaks down acetylcholine (a chemical released by nerves that activates muscle contractions) and helps to maintain proper tra [..]

An enzyme that inactivates the transmitter acetylcholine both at synaptic sites and elsewhere in the nervous system.
