RESUMO

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.
