AcetylcholinesteraseAcetylcholinesterase

Human acetylcholinesterase (AChE) is an enzyme which inhibits the function acetylcholine by way of a rapid hydrolysis. It is classified as a toxin/ hydrolase and has been linked to things such as snake venom and has been used in the the development of treatment for diseases which involve the nervous system and the transmission of signals to muscles. This specific enzyme has 3 active binding sites and 6 mutations. Each of which either causing a loss of activity or a mis-folding. You may include any references to papers as in: the use of JSmol in Proteopedia or to the article describing Jmol to the rescue. 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.
