Acetylcholinesterase

Human acetylcholinesterase (ACHE) is an enzyme which inhibits the function acetylcholine by way of a rapid hydrolysis. It is classified as a toxin and has been linked to things such as snake venom and has been used in the the development of treatment for Alzheimer's disease. This specific enzyme has 3 active binding sites and 6 mutations. Each of which either causing a loss of activity or a misfolding.

Function Acetylcholinesterase functions primarily in the synaptic cleft to stop the signal to the neurotransmitter. This is done by way of a rapid hydrolysis reaction of the neurotransmitter acetylcholine yielding the products acetate, choline and hydrogen ion.
