Chains	Enzyme Name	Description	Catalytic Residues
A	choline O-acetyltransferase M-CSA #605	Choline acetyltransferase synthesises the neurotransmitter acetylcholine from choline in neurones and other cell types. It catalyses the reversible transfer of an acetyl group between acetyl CoA and choline, and belongs to the choline/carnitine acyltranserase family which also includes enzymes involved in fatty acid metabolism.
