NADH-dependent carbonyl reductase CmCR
Ethyl (S)-4-chloro-3-hydroxybutanoate [(S)-CHBE] is a key intermediate for the production of chiral drugs, including choles- terol-lowering HMG-CoA reductase inhibitors such as Lipitor. Therefore, a more practical way to synthesize highly optical active of (S)-CHBE (>99.9% ee) is of great interest. Compared with conventional chemical synthesis, the asymmetric bioreduction of ethyl 4-chloro-3-oxobutanoate (COBE), which is inexpensive and easily synthesized, is an economical approach to the production of (S)-CHBE. From recently research, we find that there is an enzyme can efficiently catalyze this reduction reaction. In addition, this reductase is a NADH-dependent reductase, which perfectly fit our expectation——find an efficient, NADH-dependent reductase as our project can only increase the concentration of NADH inside of the cytoplasm. So, to prove our project’s feasibility, this substrate and product will be a perfect model. We introduce this enzyme to our engineered E.coli to catalyze this reaction.
