Polyol dehydrogenases (PDHs) play a pivotal role in the biotransformation between rare sugar and alcohol. Among these PDHs, mannitol 2-dehydrogenase (MDH, EC 1.1.1.67), galactitol 2-dehydrogenase (GDH, EC 1.1.1.16), ribitol 2-dehydrogenase (RDH, EC 1.1.1.56), xylitol 4-dehydrogenase (XDH, EC 1.1.1.14), and arabitol...

Dicarbonyl/L-xylulose reductase (DCXR) converts l-xylulose into xylitol, and reduces various α-dicarbonyl compounds, thus performing a dual role in carbohydrate metabolism and detoxification. In this study, we identified DHS-21 as the only DCXR ortholog in Caenorhabditis elegans. The dhs-21 gene is...
