Summation

In the second step of the glyoxalase system, hydroxyacylglutathione hydrolase (HAGH) catalyses the hydrolysis of (R)-S-lactoylglutathione ((R)-S-LGSH) to glutathione (GSH) and lactic acid (LACT) (Ridderstrom et al. 1996). The HAGH gene can produce two forms of the protein, form 1 is mitochondrial whereas form 2 is cytosolic (Cordell et al. 2004). HAGH is monomeric but requires two Zn2+ ions for activity (Cameron et al. 1999). This reaction completes the detoxification of methylglyoxal, a reactive byproduct of pyruvate metabolism.
