The budC gene coding for a new meso-2,3-butanediol dehydrogenase (BDH) from Serratia marcescens H30 was cloned and expressed in Escherichia coli BL21(DE3), purified, and characterized for its properties. The recombinant BDH with a molecular weight of 27.4 kDa exhibited a reversible transformation between acetoin and 2,3-butanediol. In the presence of NADH, BDH could catalyze the reduction of diacetyl and (3R)-acetoin to (3S)-acetoin and meso-2,3-butanediol, respectively, while (3S)-acetoin as a substrate could be further transformed into (2S, 3S)-2,3-butanediol at pH 9.0. For diol oxidation reactions, (3R)-acetoin and (3S)-acetoin were obtained when meso-2,3-butanediol and (2S,3S)-2,3-butanediol were used as the substrates with BDH and NAD(+). (2R,3R)-2,3-butanediol was not a substrate for the BDH at all. The low K m value (4.1 mM) in meso-2,3-butanediol oxidation reaction and no activity for diacetyl, acetoin, and 2,3-butanediol as the substrates with NADP(+)/NADPH suggested that the budC gene product belongs to a NAD(H)-dependent meso-2,3-BDH. Maximum activities for diacetyl and (3S/3R)-acetoin reduction were observed at pH 8.0 and pH 5.0 while for meso-2,3-butanediol oxidation it was pH 8.0. However, the optimum temperature for oxidation and reduction reactions was about 40 °C. In addition, the BDH activity for meso-2,3-butanediol oxidation was enhanced in the presence of Fe(2+) and for diacetyl and (3S/3R)-acetoin reduction in the presence of Mg(2+) and Mn(2+), while several metal ions inhibited its activity, particularly Fe(3+) for reduction of diacetyl and acetoin. Sequence analysis showed that the BDH from S. marcescens H30 possessed two conserved sequences including the coenzyme binding motif (GxxxGxG) and the active-site motif (YxxxK), which are present in the short-chain dehydrogenase/reductase superfamily. << Less
