| 1.1.1.B3 | synthesis |
synthesis of ethyl (S)-4-chloro-3-hydroxybutanoate in Escherichia coli. Coexpression of carbonyl reductase CRII and a glucose dehydrogenase gives an activity of 15 U/mg protein using ethyl 4-chloro-3-oxobutanoate as a substrate in a water/butyl acetate system. The transformants give a molar yield of 91%, and an optical purity of the (S)-isomer of more than 99% enantiomeric excess |
