General description

Glyoxalase I (GLO-1), a lactoylglutathione lyase also known as methylglyoxalase, aldoketomutase, ketone-aldehyde mutase, and (R)-S-lactoylglutathione methylglyoxal-lyase, is an enzyme that catalyzes the isomerization of hemithioacetal adducts which are formed in spontaneous reactions between glutathionyl groups and aldehydes. The primary physiological function of glyoxalase I is the detoxification of methyglyoxal, a reactive 2-oxoaldehyde that is cytostatic at low concentrations and cytotoxic at millimolar concentrations. Glyoxalase I is a target for the development of pharmaceuticals against bacteria, protozoans, and cancer.

Application

Glyoxalase I Assay Kit has been used to estimate the glyoxalase I activity in plasma samples.

Features and Benefits

Compatible with high-throughput handling systems.

Suitability

Suitable for the detection of Glyoxalase I activity in enzyme preparations and biological samples. Suitable for testing the effects of compounds on Glyoxalase I activity.

Principle

The Glyoxalase I Activity Assay kit provides a simple and direct procedure for measuring GLO-1 activity in a variety of samples such as enzyme preparations or biological samples. In this assay, the GLO-1-mediated production of S-lactoylglutathione is measured by monitoring the change in absorbance at 240 nm. One unit of Glyoxalase I is the amount of enzyme that will convert 1.0 μmole of S-lactoylglutathione from methylglyoxal and reduced glutathione per minute at pH 6.6 and 25 °C.

Persistent psychological stress often leads to anxiety disorders and depression. Benzodiazepines and selective serotonin reuptake inhibitors are popular treatment options but have limited efficacy, supporting the need for alternative treatment.

In plants, lineage-specific metabolites can be created by activities derived from the catalytic promiscuity of ancestral proteins, although examples of recruiting detoxification systems to biosynthetic pathways are scarce. The ubiquitous glyoxalase (GLX) system scavenges the cytotoxic methylglyoxal, in which GLXI

Methylglyoxal was shown to impair adipose tissue capillarization and insulin sensitivity in obese models. We hypothesized that glyoxalase-1 (GLO-1) activity could be diminished in the adipose tissue of type 2 diabetic obese patients. Moreover, we assessed whether such activity could
