Process for producing optically active 4-halo-3-hydroxybutanoate

摘要

There are provided a polynucleotide sequence coding for an amino acid sequence capable of preferentially producing (S)-4-bromo-3-hydroxybutanoate by asymmetrically reducing 4-bromo-3-oxobutanoate, a DNA construct having a promoter in operative linkage with the polynucleotide sequence, a recombinant vector comprising the polynucleotide sequence, a transformant, a recombinant vector and the like.
