abstract = {α-hydroxy ketones (HK) and 1,2-diols are important
building blocks for fine chemical synthesis. Here, we
describe the R-selective 2,3-butanediol dehydrogenase from
B. clausii DSM 8716T (BcBDH) that belongs to the
metal-dependent medium chain dehydrogenases/reductases
family (MDR) and catalyzes the selective asymmetric
reduction of prochiral 1,2-diketones to the corresponding HK
and, in some cases, the reduction of the same to the
corresponding 1,2-diols. Aliphatic diketones, like
2,3-pentanedione, 2,3-hexanedione, 5-methyl-2,3-hexanedione,
3,4-hexanedione and 2,3-heptanedione are well transformed.
In addition, surprisingly alkyl phenyl dicarbonyls, like
2-hydroxy-1-phenylpropan-1-one and phenylglyoxal are
accepted, whereas their derivatives with two phenyl groups
are not substrates. Supplementation of Mn2+ (1 mM) increases
BcBDH's activity in biotransformations. Furthermore, the
biocatalytic reduction of 5-methyl-2,3-hexanedione to mainly
5-methyl-3-hydroxy-2-hexanone with only small amounts of
5-methyl-2-hydroxy-3-hexanone within an enzyme membrane
reactor is demonstrated.},
