A carbonyl reductase (SCR2) gene was synthesized and expressed in Escherichia coli after codon optimization to investigate its biochemical properties and application in biosynthesis of ethyl (S)-4-chloro-3-hydroxybutanoate ((S)-CHBE), which is an important chiral synthon for the side chain of cholesterol-lowering drug. The recombinant SCR2 was purified and(More)
Halohydrin dehalogenases (HHDHs) are lyases that catalyze the cleavage of carbon–halogen bond of halohydrins. They also can catalyze the reverse reaction in the presence of nucleophiles such as cyanide, azide, and nitrite ions. HHDHs have been recognized as the ideal tools for the degradation of various halogenated environmental pollutants. Moreover, they(More)
Ethyl (R)-4-cyano-3-hydroxybutanoate (HN) is an important chiral synthon for side chain of the cholesterol-lowering drug atorvastatin (Lipitor), which is the hydroxymethylglutaryl CoA reductase inhibitor. HN is also used as a synthon in the production of l-carnitine and (R)-4-amino-3-hydroxybutanoic acid. It is necessary to have a clear understanding of the(More)
A codon-optimized 2-deoxyribose-5-phosphate aldolase (DERA) gene was newly synthesized and expressed in Escherichia coli to investigate its biochemical properties and applications in synthesis of statin intermediates. The expressed DERA was purified and characterized using 2-deoxyribose-5-phosphate as the substrate. The specific activity of recombinant DERA(More)
