CC -!- FUNCTION: Catalyzes the conversion of hemimercaptal, formed from
CC methylglyoxal and glutathione, to S-lactoylglutathione.
CC {ECO:0000256|RuleBase:RU361179}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-S-lactoylglutathione = glutathione + methylglyoxal;
CC Xref=Rhea:RHEA:19069, ChEBI:CHEBI:17158, ChEBI:CHEBI:57474,
CC ChEBI:CHEBI:57925; EC=4.4.1.5;
CC Evidence={ECO:0000256|ARBA:ARBA00000817,
CC ECO:0000256|RuleBase:RU361179};
CC -!- COFACTOR:
CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786;
CC Evidence={ECO:0000256|RuleBase:RU361179};
CC Note=Binds 1 nickel ion per subunit. {ECO:0000256|RuleBase:RU361179};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|PIRSR:PIRSR604361-3};
CC Note=Binds 1 zinc ion per subunit. In the homodimer, two zinc ions are
CC bound between subunits. {ECO:0000256|PIRSR:PIRSR604361-3};
CC -!- PATHWAY: Secondary metabolite metabolism; methylglyoxal degradation;
CC (R)-lactate from methylglyoxal: step 1/2.
CC {ECO:0000256|ARBA:ARBA00005008, ECO:0000256|RuleBase:RU361179}.
CC -!- SIMILARITY: Belongs to the glyoxalase I family.
CC {ECO:0000256|ARBA:ARBA00010363, ECO:0000256|RuleBase:RU361179}.
