The toxicity of recombinant proteins in Escherichia coli: a comparison of overexpression in BL21(DE3), C41(DE3), and C43(DE3).
Two mutant strains of Escherichia coli BL21(DE3), called C41(DE3) and C43(DE3) and originally described by Miroux and Walker, are frequently used to overcome the toxicity associated with overexpressing recombinant proteins using the bacteriophage T7 RNA polymerase expression system. Even when the toxicity of the plasmids is so high that it prevents transformation in the strain BL21(DE3), the to...
متن کاملGenomic and transcriptomic landscape of Escherichia coli BL21(DE3)
Escherichia coli BL21(DE3) has long served as a model organism for scientific research, as well as a workhorse for biotechnology. Here we present the most current genome annotation of E. coli BL21(DE3) based on the transcriptome structure of the strain that was determined for the first time. The genome was annotated using multiple automated pipelines and compared to the current genome annotatio...
متن کاملComplete Genome Sequence of Escherichia coli BLR(DE3), a recA-Deficient Derivative of E. coli BL21(DE3)
Escherichia coli BLR(DE3) is a commercially available recA-deficient derivative of BL21(DE3), one of the most widely used strains for recombinant protein expression. Here, we present the full-genome sequence of BLR(DE3) and highlight additional differences with its parent strain BL21(DE3) which were previously unreported but may affect its physiology.
متن کاملActivation of formate hydrogen-lyase via expression of uptake [NiFe]-hydrogenase in Escherichia coli BL21(DE3)
BACKGROUND Several recent studies have reported successful hydrogen (H2) production achieved via recombinant expression of uptake [NiFe]-hydrogenases from Hydrogenovibrio marinus, Rhodobacter sphaeroides, and Escherichia coli (hydrogenase-1) in E. coli BL21(DE3), a strain that lacks H2-evolving activity. However, there are some unclear points that do not support the conclusion that the recombin...
متن کاملExacerbation of substrate toxicity by IPTG in Escherichia coli BL21(DE3) carrying a synthetic metabolic pathway
BACKGROUND Heterologous expression systems based on promoters inducible with isopropyl-β-D-1-thiogalactopyranoside (IPTG), e.g., Escherichia coli BL21(DE3) and cognate LacI(Q)/P(lacUV5)-T7 vectors, are commonly used for production of recombinant proteins and metabolic pathways. The applicability of such cell factories is limited by the complex physiological burden imposed by overexpression of t...
