T7-RBS4-OleP

we selected high-copy plasmids pRSFDuet, medium-high copy plasmids pETDuet and pET28a, and low-copy plasmid pACYCDuet as carriers to express Olep in E. coli, and the results showed that the recombinant strains constructed with high-copy plasmid pRSFDuet as the carrier had the highest expression of p450 enzyme, cell growth rate, and substrate conversion rate. T7-RBS4-Olep is expressed by the plasmid vector pETDuet/pRSFDuet.

Usage and Biology

OleP, the cytochrome P450 epoxidase from Streptomyces antibioticus involved in Oleandomycin biosynthesis: functional analysis and crystallographic structure in complex with clotrimazole. PDB DOI: https://doi.org/10.2210/pdb4XE3/pdb Classification: OXIDOREDUCTASE Organism(s): Streptomyces antibioticus Expression System: Escherichia coli BL21(DE3)
