Thiol-disulfide exchanges modulate aldo-keto reductase family 1 member B10 activity and sensitivity to inhibitors
The reversible thiol/disulfide exchange is an important regulatory mechanism of protein enzymatic activity. Many protein enzymes are susceptible to S-thiolation induced by reactive oxygen species (ROS); and the glutathione (GSH) and free amino acid cysteine (Cys) are critical cellular thiol anti-oxidants, protecting proteins from irreversible oxidative damage. In this study, we found that aldo-keto reductase family 1 member B10 (AKR1B10) contains 4 Cys residues, i.e., Cys45, Cys187, Cys200, and Cys299. Exposing AKR1B10 to ROS mixtures resulted in significant decrease of its free sulfhydryl groups, up to 40-50% in the presence of physiological thiol cysteine at 0.5 or 1.0 mM; and accordingly, AKR1B10 enzymatic activity was reversibly decreased, in parallel with the oxidation of the sulfhydryl groups. ROS-induced thiolation also affected the sensitivity of AKR1B10 to inhibitors EBPC, epalrestat, and statil. Together our results showed for the first time that AKR1B10’s enzymatic activity and inhibitor sensitivity are modulated by thiol/disulfide exchanges.
