Protein
Sorbitol dehydrogenase
Organism
Rhodobacter sphaeroides
Function
Catalyzes the oxidation of D-sorbitol (D-glucitol) to D-fructose. Can also catalyze the oxidation of galactitol to D-tagatose and the oxidation of L-iditol, with lower efficiency.
Similarity
Belongs to the short-chain dehydrogenases/reductases (SDR) family.
