Sorbitol dehydrogenase

sorbitol dehydrogenase, L-Iditol 2-Dehydrogenase
Sorbitol dehydrogenase (SORD; EC catalyzes the interconversion of polyols and their corresponding ketoses, and together with aldose reductase (ALDR1; MIM 103880), makes up the sorbitol pathway that is believed to play an important role in the development of diabetic complications (summarized by Carr and Markham, 1995 [PubMed 8535074]). The first reaction of the pathway (also called the polyol pathway) is the reduction of glucose to sorbitol by ALDR1 with NADPH as the cofactor. SORD then oxidizes the sorbitol to fructose using NAD(+) cofactor.[supplied by OMIM, Jul 2010] (from NCBI)

Serum gamma-glutamyl transferase (GGT) and sorbitol dehydrogenase (SDH) were not significantly altered by the surgical procedure; however, aspartate aminotransferase (AST) and amylase (AMY) were transiently increased.
A competitive chemical-proteomic platform to identify zinc-binding cysteines.
Weerapana et al., Boston, United States. In Acs Chem Biol, Feb 2014
As validation of our platform, we utilize a peptide-based cysteine-reactive probe to show that the known Zn(2+)-chelating cysteine in sorbitol dehydrogenase (SORD) demonstrates an expected loss in nucleophilicity in the presence of Zn(2+) ions and a gain in nucleophilicity upon treatment with a Zn(2+) chelator.
