Secondary Information

Presence in other biological fluids/tissue/cells expressed in cholinergic neurons
Protein Function termination of impulse transmission at cholinergic synapses by rapid hydrolysis of the neurotransmitter, acetylcholine; serine hydrolases; key role in ending cholinergic neurotransmission
Biochemical Properties possesses a high specific activity, functioning at a rate approaching that of a diffusion controlled reaction; potent irreversible inhibitors- organophosphorus (OP) poisons; active site of AChE contains two subsites, the ‘esteratic’ and ‘anionic’ subsites; type α/β hydrolase folded with an α helix bound with β sheet that contains a catalytic domain38 with catalytic triad Ser – His – Glu
