CC -!- FUNCTION: Esterase with broad substrate specificity. Contributes to the
CC inactivation of the neurotransmitter acetylcholine. Can degrade
CC neurotoxic organophosphate esters (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an acylcholine + H2O = a carboxylate + choline + H(+);
CC Xref=Rhea:RHEA:21964, ChEBI:CHEBI:15354, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:29067, ChEBI:CHEBI:35287; EC=3.1.1.8;
CC -!- SUBUNIT: Homotetramer; disulfide-linked. Dimer of dimers (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the type-B carboxylesterase/lipase family.
CC {ECO:0000305}.
