Codon Optimization> | The codon-optimized genes of epoxide hydrolase (EH, Genbank: KX146840.1), lipase 3646 (Lip3646, Genbank: JX833623), and carbonyl reductase (AcCR, Genbank: MF419650) from Sphingomonas sp. HXN-200, Cohnella sp. A01, and Acetobacter sp. CCTCC M209061, respectively, were synthetized by GenScript Biotech Corp. | Get A Quote |
A robust Escherichia coli (E. coli) strain, with a dual protection system to fight against microbial contamination and T7 phage infection, is used as a chassis to overexpress various proteins in auxotrophic MOPS medium. Among them, a robust EH (epoxide hydrolase)-producing E. coli was used as a biocatalyst to enantioselectively resolve racemic glycidyl o-methylphenyl ether (rac-o-GMPE) for preparing (R)-o-GMPE with 6416.7 U/g wet cells. The optimal temperature, pH and biocatalyst dosage were 25 °C, 7.0 and 0.2 mg/mL in aqueous buffer, respectively. The maximal yield (23.0 %) and ee (99.2 %) were achieved within 12 min in 20 mM rac-o-GMPE. Additionally, 98.0 % ee and 38.7 % yield were observed by cell... More
