Abstract: Abstract Ketoreductase ChKRED12 from Chryseobacterium sp. CA49 was identified as a highly stereoselective catalyst for the bioreductive production of (2S,3S)-ethyl 3-hydroxy-2-methoxy-3-phenylpropanoate (EMHP) through dynamic kinetic resolution. Its performance was further improved using semi-rational design strategies… read more here.
