enantioselective 1,2-reduction of alpha,beta-unsaturated ketones and aryl ketones by perakine reductase. Perakine reductase catalyzes asymmetric reduction of enones and aromatic ketones, leading to alpha-allylic alcohols and alpha-aromatic alcohols. It is NADPH-dependent. Among the evaluated substances, 4'-nitroacetophenone is found to be the best ketone substrate, with yield and enantiomeric excess values exceeding 99%.
