additional information the selectivity factor E reflecting the relative rate of the reaction of the two enantiomers is only 4.6 for the wild-type enzyme, in slight favor of the (S)-product, a value of 10.8 is observed with the natural EH variant IS002B1 with the three amino acid exchanges A217V, K332E and A390E. A value of 7.4 is observed with the natural variant IR003B1 with the amino acid exchange R219G, a value of 6.6 is observed with the natural variant IB001C2 with the amino acid exchange F340Y, a value of 6.4 is observed with the natural variant IE001H6 with the amino acid exchange A327V, a value of 6.2 is observed with the natural variant IS001H8 with the amino acid exchange A327V and a value of 5.5 is observed with the natural variant IL001D4 with the amino acid exchange P222S Aspergillus niger
