Definitions for lactoylglutathione lyase
This page provides all possible meanings and translations of the word lactoylglutathione lyase
A glyoxalase enzyme that catalyzes the isomerization of hemithioacetal adducts.
In enzymology, a lactoylglutathione lyase is an enzyme that catalyzes the isomerization of hemithioacetal adducts, which are formed in a spontaneous reaction between a glutathionyl group and aldehydes such as methylglyoxal. Glyoxalase I derives its name from its catalysis of the first step in the glyoxalase system, a critical two-step detoxification system for methylglyoxal. Methylglyoxal is produced naturally as a byproduct of normal biochemistry, but is highly toxic, due to its chemical reactions with proteins, nucleic acids, and other cellular components. The second detoxification step, in which-S-lactoylglutathione is split into glutathione and D-lactate, is carried out by glyoxalase II, a hydrolase. Unusually, these reactions carried out by the glyoxalase system does not oxidize glutathione, which usually acts as a redox coenzyme. Although aldose reductase can also detoxify methylgloxal, the glyoxalase system is more efficient and seems to be the most important of these pathways. Glyoxalase I is an attractive target for the development of drugs to treat infections by some parasitic protozoa, and cancer. Several inhibitors of glyoxalase I have been identified, such as S-glutathione.
U.S. National Library of Medicine
