一般描述
Glyoxalase detoxification system consists of glyoxalase (GLO)-I and GLO-II. GLO-I is a cytosolic, 42 kDa, dimeric Zn2+ metalloenzyme.
应用
Glyoxalase I from Saccharomyces cerevisiae has been used as a standard in Glyoxalase I assay for C. dilatata females and brooded encapsulated embryos. It has also been used as a standard for calibration curve generation for quantifying glyoxalase I from brain tissues and cerebral microvessels.
生化/生理作用
Glyoxalase I is universally expressed and involved in the protection against cellular damage due to cytotoxic metabolites such as advanced glycation end products (AGEs). It is an integral component of the detoxification system, catalyzing the conversion of reactive, acyclic a-oxoaldehydes into the corresponding a-hydroxyacids in a glutathione-dependent manner.

Glucose consumption and therefore methylglyoxal production of human erythrocytes increase significantly upon infection with malaria parasites. The glyoxalase systems of the host-parasite unit cope with this metabolic challenge by catalyzing the removal of harmful methylglyoxal. Thus, glyoxalase 1 from the
