CC -!- FUNCTION: Thiolesterase that catalyzes the hydrolysis of S-D-lactoyl-
CC glutathione to form glutathione and D-lactic acid. {ECO:0000255|HAMAP-
CC Rule:MF_01374}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=an S-(2-hydroxyacyl)glutathione + H2O = a 2-hydroxy
CC carboxylate + glutathione + H(+); Xref=Rhea:RHEA:21864,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57925,
CC ChEBI:CHEBI:58896, ChEBI:CHEBI:71261; EC=3.1.2.6;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01374};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01374};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_01374};
CC -!- PATHWAY: Secondary metabolite metabolism; methylglyoxal degradation;
CC (R)-lactate from methylglyoxal: step 2/2. {ECO:0000255|HAMAP-
CC Rule:MF_01374}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_01374}.
CC -!- SIMILARITY: Belongs to the metallo-beta-lactamase superfamily.
CC Glyoxalase II family. {ECO:0000255|HAMAP-Rule:MF_01374}.
