**Background of HAGH Recombinant Protein**
HAGH (Hydroxyacylglutathione Hydrolase), also known as Glyoxalase II (GLO2), is a critical enzyme in the glyoxalase system, a ubiquitous metabolic pathway responsible for detoxifying methylglyoxal (MG), a highly reactive byproduct of glycolysis. MG accumulation is cytotoxic, leading to protein and DNA damage linked to diabetes complications, neurodegenerative disorders, and cancer. The glyoxalase system converts MG into D-lactate via a two-step process: Glyoxalase I (GLO1) first catalyzes the isomerization of MG and glutathione into S-D-lactoylglutathione, which is subsequently hydrolyzed by HAGH into glutathione and D-lactate.
As a zinc-dependent metalloenzyme, HAGH plays a dual role in cellular detoxification and glutathione homeostasis. Its structure features a conserved binuclear metal-binding site essential for catalytic activity. Dysregulation of HAGH has been implicated in oxidative stress-related pathologies, making it a potential therapeutic target.
Recombinant HAGH protein is produced using genetic engineering techniques, such as cloning the HAGH gene into bacterial, yeast, or mammalian expression systems, followed by purification. This engineered protein retains enzymatic activity and is widely used in biochemical research to study MG metabolism, evaluate enzyme kinetics, and screen inhibitors for drug development. Additionally, it aids in exploring HAGH’s role in diseases like Alzheimer’s, where MG toxicity contributes to neurodegeneration.
Overall, HAGH recombinant protein serves as a vital tool for understanding cellular stress responses and developing therapies targeting the glyoxalase pathway. Its applications span basic research, diagnostics, and therapeutic innovation.
