SORD, also known as sorbitol dehydrogenase, is a member of the zinc-containing alcohol dehydrogenase family. It is widely expressed with highest expression in kidney and in the lens of the eye. SORD enzymatically catalyzes the zinc-dependent interconversion of polyols, such as sorbitol and xylitol, to their respective ketoses. Source: Recombinant protein corresponding to aa1-357 from human SORD expressed in E. coli. Molecular Weight: ~38.3kD (357aa) Specific Activity: >15units/mg, and is defined as the amount of enzyme that catalyze the reduction 1umole of D-fructose to D-sorbitol/minute at pH 7.5 and 37C.
