Deciphering the transcriptional changes in Escherichia coli strains C41(DE3) and C43(DE3) that makes them a superior choice for membrane protein production.
Abstract:Background: The production of membrane proteins for functional and structural protein analysis remains a bottleneck in the continuing quest for understanding biological systems. For recombinant membrane proteins, the Walker strains C41(DE3) and C43(DE3) are a valuable tool because they are capable of producing levels of functional protein that would otherwise be toxic to the cell. At the genome level, amongst only a handful of genetic changes, mutations in the lacUV5 promoter region upstream from the bacteriop… Show more
