Substrate Specificity, Inhibitor Selectivity and Structure-Function Relationships of Aldo-Keto Reductase 1B15: A Novel Human Retinaldehyde Reductase
Human aldo-keto reductase 1B15 (AKR1B15) is a newly discovered enzyme which shares 92% amino acid sequence identity with AKR1B10. While AKR1B10 is a well characterized enzyme with high retinaldehyde reductase activity, involved in the development of several cancer types, the enzymatic activity and physiological role of AKR1B15 are still poorly known. Here, the purified recombinant enzyme has be...
متن کاملComparative anatomy of the aldo-keto reductase superfamily.
The aldo-keto reductases metabolize a wide range of substrates and are potential drug targets. This protein superfamily includes aldose reductases, aldehyde reductases, hydroxysteroid dehydrogenases and dihydrodiol dehydrogenases. By combining multiple sequence alignments with known three-dimensional structures and the results of site-directed mutagenesis studies, we have developed a structure/...
متن کاملAcceleration of an aldo-keto reductase by minimal loop engineering
Aldo-keto reductases tighten coenzyme binding by forming a hydrogen bond across the pyrophosphate group of NAD(P)(H). Mutation of the hydrogen bonding anchor Lys24 in Candida tenuis xylose reductase prevents fastening of the "safety belt" around NAD(H). The loosened NAD(H) binding leads to increased turnover numbers (k(cat)) for reductions of bulky-bulky ketones at constant substrate and coenzy...
متن کاملAldo–Keto Reductase AKR1C1–AKR1C4: Functions, Regulation, and Intervention for Anti-cancer Therapy
Aldo-keto reductases comprise of AKR1C1-AKR1C4, four enzymes that catalyze NADPH dependent reductions and have been implicated in biosynthesis, intermediary metabolism, and detoxification. Recent studies have provided evidences of strong correlation between the expression levels of these family members and the malignant transformation as well as the resistance to cancer therapy. Mechanistically...
متن کاملAldo-keto reductase family 1 member B8 is secreted via non-classical pathway.
Mouse aldo-keto reductase family 1 member B8 (AKR1B8) has the highest similarity to human aldo-keto reductase family 1 member B10 (AKR1B10), a secretory protein through lysosomes-mediated non-classical secretory pathway. To identify whether AKR1B8 is secreted through the same pathway, we carried out this study. Self-developed sandwich ELISA and western blot were used to detect AKR1B8 in cells a...
