Glutathione-independent glyoxalase HSP31

Gene

HSP31

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the conversion of methylglyoxal (MG) to D-lactate in a single glutathione (GSH)-independent step. May play a role in detoxifying endogenously produced glyoxals (PubMed:24302734). Involved in protection against reactive oxygen species (ROS) (PubMed:17395014). Important for viability in stationary phase. May negatively regulate TORC1 in response to nutrient limitation (PubMed:24706893).3 Publications

Catalytic activityi
