selected as targets for mutagenesis, in order to enhance YbfF activity and enantioselectivitytowards IPG esters. Random mutagenesis at positions 25, 124, 185 and 235 yielded several best YbfF variants with enhanced activity and enantioselectivitytowards IPG esters. The best YbfF mutant, W235I, exhibited a 2-fold higher enantioselectivity than wild-type YbfF, with an E=38 for IPG butyrate and an E=77
