lactoylglutathione lyase activity

Definition

Target type: molecularfunction

Catalysis of the reaction: (R)-S-lactoylglutathione = glutathione + methylglyoxal. [EC:4.4.1.5, RHEA:19069]

Lactoylglutathione lyase activity catalyzes the reversible cleavage of S-lactoylglutathione, a detoxification product of methylglyoxal, into glutathione and pyruvate. This reaction is crucial for maintaining cellular redox homeostasis and preventing oxidative stress. Methylglyoxal is a highly reactive α-oxoaldehyde that can damage cellular macromolecules, including proteins and DNA. S-lactoylglutathione is formed when glutathione reacts with methylglyoxal, and its cleavage by lactoylglutathione lyase removes the toxic methylglyoxal from the cell. This enzyme is therefore an important component of the cellular defense system against oxidative stress. Lactoylglutathione lyase activity also plays a role in the detoxification of other α-oxoaldehydes, including glyoxal and 3-deoxyglucosone. These compounds are also highly reactive and can cause cellular damage. Lactoylglutathione lyase activity can therefore be seen as a general defense mechanism against reactive α-oxoaldehydes. This enzyme is found in a wide range of organisms, including bacteria, yeast, plants, and animals. In humans, lactoylglutathione lyase is expressed in various tissues, including the liver, kidney, and brain. Its activity is essential for maintaining normal cellular function and preventing disease.'
