CC -!- FUNCTION: Catalyzes the reversible synthesis of acetylcholine (ACh)
CC from acetyl CoA and choline at cholinergic synapses.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetyl-CoA + choline = acetylcholine + CoA;

CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57288; EC=2.3.1.6;
CC -!- SIMILARITY: Belongs to the carnitine/choline acetyltransferase family.
CC {ECO:0000305}.
