Acetyl cholinesterase (AChE) is an enzyme with a catalytic function of hydrolysing the neurotransmitter acetylcholine (Ach) into its two elements: choline and acetate. This reaction happens at the junctional fold in the synaptic cleft where acetylcholine is exported out by the secretory vesicles from the presynaptic knob and flow across the synapse. The acetylcholine interacts and bind to the postsynaptic receptor to transmit the signal[1]. The removal of neurotransmitter after the signal transmission at the postsynaptic membrane is vital in order to enable the generation of new action potential by stimulus.
