additional information | the enzyme is also active in reduction reaction with diacetyl (91% compared to (2R,3S)-acetoin) and glyceraldehyde-3-phosphate (12% compared to (2R,3S)-acetoin), cf. EC 1.1.1.303 and EC 1.1.1.8, respectively, but not with dihydroxyacetone phosphate. It shows low activity in oxidation reaction with ethanol, n-propanol, n-butanol, 1,3-propanediol, and 1,5-pentanediol | Paenibacillus polymyxa | ? | - |

General Information | Comment | Organism |
---|---|---|
evolution | the (2R,3R)-2,3-butanediol dehydrogenase belongs to the mostly zinc-containing medium-chain dehydrogenase/reductase superfamily and not to the short-chain dehydrogenase/reductase superfamily, to which meso- and (2S,3S)-2,3-butanediol dehydrogenases belong, phylogenetic analysis. The enzyme contains two hydrophobic residues forming the binding site for cofactor NAD(P), Phe138 and Leu141 (numbers refer to R,R-BDH of Saccharomyces cerevisiae) | Paenibacillus polymyxa |
