General annotation (Comments)

Function

Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters By similarity.

Catalytic activity

An acylcholine + H2O = choline + a carboxylate.

Subunit structure

Homotetramer; disulfide-linked. Dimer of dimers By similarity.

Subcellular location

Secreted By similarity.

Tissue specificity

Present in most cells except erythrocytes.

Sequence similarities

Belongs to the type-B carboxylesterase/lipase family.
