General annotation (Comments)

Function	Catalyzes the conversion of hemimercaptal, formed from methylglyoxal and glutathione, to S-lactoylglutathione.
Catalytic activity	(R)-S-lactoylglutathione = glutathione + methylglyoxal.
Cofactor	Binds 1 zinc ion per subunit.
Pathway	Secondary metabolite metabolism; methylglyoxal degradation; (R)-lactate from methylglyoxal: step 1/2.
Subunit structure	Monomer.
Sequence similarities	Belongs to the glyoxalase I family.
