AKR1A1 (aldo-keto reductase family 1 member A1) is a NADPH-dependent oxidoreductase belonging to the aldo-keto reductase superfamily. It plays a critical role in cellular detoxification, antioxidant defense, and metabolic pathways by catalyzing the reduction of various endogenous and exogenous carbonyl-containing compounds, including aldehydes, ketones, and quinones. This enzyme is particularly notable for its involvement in metabolizing toxic lipid peroxidation products (e.g., 4-hydroxynonenal), glucose-derived aldehydes, and xenobiotics. It also participates in ascorbate (vitamin C) biosynthesis in some species by reducing gulonolactone.
Recombinant AKR1A1 protein is engineered through genetic cloning and expression in heterologous systems like *E. coli* or mammalian cells, enabling large-scale production for functional studies. Researchers utilize this purified protein to investigate its enzymatic mechanisms, substrate specificity, and structural features, including its conserved (α/β)8-barrel fold and catalytic tetrad. Its recombinant form is essential for studying oxidative stress-related pathologies, such as neurodegenerative diseases, diabetes, and cancer, where AKR1A1 dysregulation has been implicated. Additionally, it serves as a tool for screening potential inhibitors or modulators for therapeutic development. Studies also explore its role in metabolic disorders linked to carbonyl overload and its interplay with other redox-regulating enzymes. As a highly conserved enzyme across mammals, AKR1A1 recombinant protein provides insights into species-specific metabolic adaptations and evolutionary biology.
