An NADH-dependent reductase (ScCR) from Streptomyces coelicolor was discovered by genome mining for carbonyl reductases. ScCR was overexpressed in Escherichia coli BL21, purified to homogeneity and its catalytic properties were studied. This enzyme catalyzed the asymmetric reduction of a broad

We cloned and sequenced the gene encoding an NADPH-dependent aldehyde reductase (ARII) in Sporobolomyces salmonicolor AKU4429, which reduces ethyl 4-chloro-3-oxobutanoate (4-COBE) to ethyl (S)-4-chloro-3-hydroxybutanoate. The ARII gene is 1,032 bp long, is interrupted by four introns, and encodes a 37,315-Da

The asymmetric reduction of ethyl 4-chloro-3-oxobutanoate (COBE) to ethyl (R)-4-chloro-3-hydroxybutanoate [(R)-CHBE] using Escherichia coli cells, which coexpress both the aldehyde reductase gene from Sporobolomyces salmonicolor and the glucose dehydrogenase (GDH) gene from Bacillus megaterium as a catalyst was investigated. In

Formate dehydrogenases (FDH) are useful for the regeneration of NADH, which is required for asymmetric reduction by several dehydrogenases and reductases. FDHs have relatively low activity and are labile, especially to alpha-haloketones, thus FDH cannot be applied to the industrial

Escherichia coli M15 (pQE30-car0210) was constructed to express carbonyl reductase (CAR) by cloning the car gene from Candida magnoliae and inserting it into pQE30. By cultivating E. coli M15 (pQE30-car0210) and M15 (pQE30-gdh0310), 8.2-fold and 12.3-fold enhancements in specific enzymatic
