Meso-2,3-butanediol dehydrogenase

UniProtKB accession:  H9XP47

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the NAD-dependent oxidation of meso-2,3-butanediol to (3R)-acetoin, and of (2S,3S)-2,3-butanediol to (3S)-acetoin, with much lower efficiency (PubMed:23666479). Can also oxidize several primary alcohols such as glycerol, 1-2-pentanediol and 1,2-propanediol, with lower activity (PubMed:23666479). Cannot use (2R,3R)-2,3-butanediol (PubMed:23666479). In the presence of NADH, catalyzes the reduction of (3R)-acetoin to meso-2,3-butanediol, of (3S)-acetoin to (2S,3S)-2,3-butanediol and of diacetyl to (3S)-acetoin (PubMed:23666479). No activity is detected with NADPH/NADP(+) (PubMed:23666479).
