Also called cholinesterase, it is a hydrolytic enzyme that regulates the level of acetylcholine at cholinergic synapses and neuromuscular junctions. It serves to stop further postsynaptic nerve impulses by destroying acetylcholine after it is released from the terminal boutons of presynaptic neurons and postsynaptic receptors.
