CC   -!- FUNCTION: Serine hydrolase involved in the detoxification of
CC       formaldehyde. Hydrolyzes S-formylglutathione to glutathione and formate
CC       (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + S-formylglutathione = formate + glutathione + H(+);
CC         Xref=Rhea:RHEA:14961, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:15740, ChEBI:CHEBI:57688, ChEBI:CHEBI:57925; EC=3.1.2.12;
CC   -!- SIMILARITY: Belongs to the esterase D family. {ECO:0000305}.
