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   -!- SUBUNIT: Homotetramer; disulfide-linked. Dimer of dimers (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Present in most cells except erythrocytes.
CC   -!- SIMILARITY: Belongs to the type-B carboxylesterase/lipase family.
CC       {ECO:0000305}.
