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.

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)
