A synthetic gene circuit for measuring autoregulatory feedback control.
Autoregulatory feedback loops occur in the regulation of molecules ranging from ATP to MAP kinases to zinc. Negative feedback loops can increase a system's robustness, while positive feedback loops can mediate transitions between cell states. Recent genome-wide experimental and computational studies predict hundreds of novel feedback loops. However, not all physical interactions are regulatory,...
متن کاملOptimization 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...
متن کاملEmergent bistability by a growth-modulating positive feedback circuit.
Synthetic gene circuits are often engineered by considering the host cell as an invariable 'chassis'. Circuit activation, however, may modulate host physiology, which in turn can substantially impact circuit behavior. We illustrate this point by a simple circuit consisting of mutant T7 RNA polymerase (T7 RNAP*) that activates its own expression in the bacterium Escherichia coli. Although activa...
متن کاملOver Expression of Biologically Active Interferon Beta Using Synthetic Gene in E. coli
In this study, our previously reported novel synthetic gene encoding 166 residues of interferon-? was used for an efficient expression of IFN-?. The synthetic gene was cloned into pET21a expression vector and transferred into E. coli. Recombinant protein was over-expressed in the E. coli. Identity of the recombinant protein was confirmed by western blot analysis. The recombinant protein was bio...
