Protein
D-threitol dehydrogenase
Organism
Mycobacterium smegmatis (strain ATCC 700084 / mc(2)155)
Function
Catalyzes the NAD-dependent reversible oxidation of D-threitol. Involved in the degradation pathway of D-threitol, that allows M.smegmatis to grow on this compound as the sole carbon source. Does not catalyze the oxidation of xylitol, L-sorbitol, and L-sorbose.
Similarity
Belongs to the short-chain dehydrogenases/reductases (SDR) family.
