   1.1.1.B20 | physiological function |
Paenibacillus brasilensis produces 2,3-butanediol (2,3-BDO). And although the gene encoding (S,S)-2,3-butanediol dehydrogenase (EC 1.1.1.76) is found in the genome of Paenibacillus brasilensis strain PB24, only R,R-2,3-butanediol ((R,R)-2,3-butanediol dehydrogenase, EC 1.1.1.4) and meso-2,3-butanediol are detected by gas chromatography under the growth conditions tested. The enzyme is bifunctional as R,R-2,3-butanediol dehydrogenase/meso-2,3-butanediol dehydrogenase/diacetyl reductase |

| 1.1.1.B20 | physiological function |
the meso-2,3-butanediol dehydrogenase (meso-2,3-BDH) catalyzes NAD+-dependent conversion of meso-2,3-butanediol to acetoin (AC), a crucial external energy storage molecule in fermentive bacteria. The interconversion between (3R)-AC and meso-2,3-BD or (3S)-AC and (2S,3S)-2,3-BD is catalyzed by meso-2,3-butanediol dehydrogenase (meso-2,3-BDH) |
