To compare NADH-regeneration systems for the synthesis of (S)-4-chloro-3-hydroxybutanoate (ECHB), a novel NADH-dependent carbonyl reductase (KaCR1), which reduced ethyl 4-chloroacetoacetate (ECAA) to form (S)-ECHB, was screened and purified from Kluyveromyces aestuarii and a gene encoding KaCR1 was cloned. Glucose dehydrogenase

Bioscience, biotechnology, and biochemistry, 64(7), 1430-1436 (2000-08-17)
An NADPH-dependent carbonyl reductase (S1) isolated from Candida magnoliae catalyzed the reduction of ethyl 4-chloro-3-oxobutanoate (COBE) to ethyl (S)-4-chloro-3-hydroxybutanoate (CHBE), with a 100% enantiomeric excess, which is a useful chiral building block for the synthesis of pharmaceuticals. The gene encoding

Thiobacillus sp. strain KNK65MA, which produced an NAD-dependent formate dehydrogenase (FDH) highly resistant to alpha-haloketones, was newly isolated, i.e., the enzyme showed no loss of activity after a 5-h incubation with alpha-haloketones, such as ethyl 4-chloro-3-oxobutanoate. The enzyme was also
