General annotation (Comments)

Function	Catalyzes the conversion of hemimercaptal, formed from methylglyoxal and glutathione, to S-lactoylglutathione By similarity.
Catalytic activity	(R)-S-lactoylglutathione = glutathione + methylglyoxal.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Pathway	Secondary metabolite metabolism; methylglyoxal degradation; (R)-lactate from methylglyoxal: step 1/2.
Tissue specificity	Expressed in callus, stem, leaves, panicles and maturing seeds (at protein level). Ref.1 Ref.4
Post-translational modification	Phosphorylated after gibberellin treatment. Ref.5
Allergenic properties	Causes an allergic reaction in human. Binds to IgE. Ref.1
Sequence similarities	Belongs to the glyoxalase I family.
Biophysicochemical properties	Kinetic parameters: KM=7.6 mM for methylglyoxal
