Galactitol 2-dehydrogenase (L-tagatose-forming)

UniProtKB accession:  C0KTJ6

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the interconversion of galactitol to the rare sugar L-tagatose (PubMed:7551050). Shows activity with a wide range of substrates, and catalyzes the oxidation of a variety of polyvalent aliphatic alcohols and polyols to the corresponding ketones and ketoses, respectively, and in the reverse reaction, it reduces ketones with high stereoselectivity yielding the corresponding S-configurated alcohols (PubMed:7551050, PubMed:15296184). Shows high activity with D-threitol, xylitol, 1,2-hexanediol, 1,2-pentanediol, 2-hexanol, L-erythrulose, D-ribulose and acetoin (PubMed:7551050). Specific for NAD(+) (PubMed:7551050).
