CC -!- FUNCTION: Catalyzes the conversion of methylglyoxal (MG) or glyoxal
CC (GO) to D-lactate or glycolic acid respectively in a single glutathione
CC (GSH)-independent step. May play a role in detoxifying endogenously
CC produced glyoxals. Involved in protection against glyoxal-induced cell
CC death. {ECO:0000269|PubMed:22523093}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + methylglyoxal = (R)-lactate + H(+);
CC Xref=Rhea:RHEA:27754, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16004, ChEBI:CHEBI:17158; EC=4.2.1.130;
CC Evidence={ECO:0000269|PubMed:22523093};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.3 mM for methylglyoxal {ECO:0000269|PubMed:22523093};
CC KM=3.61 mM for glyoxal {ECO:0000269|PubMed:22523093};
CC Note=kcat is 13.8 min(-1) with methylglyoxal as substrate and 356.4
CC min(-1) with glyoxal as substrate. {ECO:0000269|PubMed:22523093};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:22523093}. Nucleus
CC {ECO:0000269|PubMed:22523093}. Note=Ubiquitously localized throughout
CC the whole cells with higher expression in the nucleus.
CC {ECO:0000269|PubMed:22523093}.
CC -!- TISSUE SPECIFICITY: Expressed exclusively in the intestine.
CC {ECO:0000269|PubMed:22523093}.
CC -!- SIMILARITY: Belongs to the peptidase C56 family. {ECO:0000305}.
