The diketone compound, benzil is reduced to (S)-benzoin with living Bacillus cereus cells. Recently, we isolated a gene responsible for benzil reduction, and Escherichia coli cells in which this gene was overexpressed transformed benzil to (S)-benzoin. Although this benzil reductase showed high identity to the short-chain dehydrogenase/reductase (SDR) family, enzymological features were unknown. Here, we demonstrated that many B. cereus strains had benzil reductase activity in vivo, and that the benzil reductases shared 94-100% amino acid identities. Recombinant B. cereus benzil reductase produced optically pure (S)-benzoin with NADPH in vitro, and the ketone group distal to a benzene ring was asymmetrically reduced. B. cereus benzil reductase showed 31% amino acid identity to the yeast open reading frame YIR036C protein and 28-30% to mammalian sepiapterin reductases, sharing the seven residues consensus for the SDR family. We isolated the genes encoding yeast YIR036C protein and gerbil sepiapterin reductase, and both recombinant proteins also reduced benzil to (S)-benzoin in vitro. Green fluorescent protein-tagged B. cereus benzil reductase distributed in the bipolar cytoplasm in B. cereus cells. Asymmetric reduction with B. cereus benzil reductase, yeast YIR036C protein and gerbil sepiapterin reductase will be utilized to produce important chiral compounds. << Less

Benzil was reduced stereospecifically to (S)-benzoin by Bacillus cereus strain Tim-r01. To isolate the gene responsible for asymmetric reduction, we constructed a library consisting of Escherichia coli clones that harbored plasmids expressing Bacillus cereus genes. The library was screened using the halo formation assay, and one clone showed benzil reduction to (S)-benzoin. Thus, this clone seemed to carry a plasmid encoding a Bacillus cereus benzil reductase. The deduced amino acid sequence had marked homologies to the Bacillus subtilis yueD protein (41% identity), the yeast open reading frame YIR036C protein (31%), and the mammalian sepiapterin reductases (28% to 30%), suggesting that benzil reductase is a novel short-chain de-hydrogenases/ reductase. << Less
