Optimization and High Level Production of Recombinant Synthetic Streptokinase in E. coli Using Response Surface Methodology
Streptokinase (SK) is an extracellular protein comprising 414 amino acids with considerable clinical importance as a commonly used thrombolytic agent. Due to its wide spread application and clinical importance designing more efficient SK production platforms worth investigatinginvestigation. In this regard, a synthetic SK gene was optimized and cloned in to pET21b plasmid for periplasmic expres...

conclusions the obtained results indicate that rsm is an effective method for the optimization of culture conditions for hes gene expression in e. coli. results a maximum rhes mrna level of 376.16% was obtained under the following conditions: 0.6 mm iptg, 7 hours post-induction time, and 0.9 cell density before induction. the level of rhes mrna was significantly correlated with post-induction t...
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 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...
