Due to favourable partition coefficients the highly enantioselective reduction of 2-octanone, catalysed by an alcohol dehydrogenase from Lactobacillus brevis, is faster in a biphasic system containing buffer and the ionic liquid [BMIM][(CF(3)SO(2))(2)N] compared to the reduction in a biphasic system containing buffer and methyl tert-butyl ether.

An anti-Prelog alcohol dehydrogenase from Oenococcus oeni that reduces 2-octanone to (R)-2-octanol was purified by 26-fold to homogeneity. The enzyme had a homodimeric structure consisting of 49 kDa subunits, required NADPH, but not NADH, as a cofactor and was a Zn-independent short-chain dehydrogenase. Aliphatic methyl ketones (chain length > or =6 carbon atoms) and aromatic methyl ketones were the preferred substrates for the enzyme, the best being 2-octanone. Maximum enzyme activity with 2-octanone was at 45 degrees C and at pH 8.0.

Enzymes of the non-conventional yeast Yarrowia lipolytica seem to be tailor-made for the conversion of lipophilic substrates. Herein, we cloned and overexpressed the Zn-dependent alcohol dehydrogenase ADH2 from Yarrowia lipolytica in Escherichia coli. The purified enzyme was characterized in vitro. The substrate scope for YlADH2 mediated oxidation and reduction was investigated spectrophotometrically and the enzyme showed a broader substrate range than its homolog from Saccharomyces cerevisiae. A preference for secondary compared to primary alcohols in oxidation direction was observed for YlADH2. 2-Octanone was investigated in reduction mode in detail. Remarkably, YlADH2 displays perfect (S)-selectivity and together with a highly (R)-selective short chain dehydrogenase/ reductase from Yarrowia lipolytica it is possible to access both enantiomers of 2-octanol in >99% ee with Yarrowia lipolytica oxidoreductases.
