Lactoylglutathione lyase (GLO1)

Links to databases


GLO1 (also known as glyoxalase I) is an enzyme that catalyzes the conversion of hemimercaptal to S-lactoylglutathione. This is the first step in the critical glyoxalase system that detoxifies methylglyoxal, a byproduct of normal biochemistry that is highly toxic due to its reactivity with proteins, nucleic acids, and other cellular components. GLO1 is also involved in the regulation of TNF-induced transcriptional activity of NF-kappa-B. Inhibition studies indicate that GLO1-mediated reduction of methylglyoxal is required for normal osteoclastogenesis.
