A (2R,3R)-2,3-butanediol dehydrogenase (BDH99::67) from Paenibacillus polymyxa ATCC 12321 was functionally characterized. The genetic characteristics of BDH99::67 are completely different from those of meso- and (2S,3S)-2,3-butanediol dehydrogenases. The results showed that BDH99::67 belongs to the 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.
从多粘类芽孢杆菌 ATCC 12321 中分离得到一种 (2R,3R)-2,3-丁二醇脱氢酶(BDH99::67),并对其进行了功能表征。BDH99::67 的遗传特征与 meso-和 (2S,3S)-2,3-丁二醇脱氢酶完全不同。结果表明,BDH99::67 属于中链脱氢酶/还原酶超家族,而不属于 meso-和 (2S,3S)-2,3-丁二醇脱氢酶所属的短链脱氢酶/还原酶超家族。
