Maximizing the expression of the MutT4 enzyme in E.coli

open in viewerMaximizing protein expression in bacterial systems requires a deep understanding of the regulatory mechanisms influencing mRNA expression and protein yield. This project focuses on optimizing protein expression by manipulating the lac operon system in E. coli and investigating the impact of various factors on protein stability and yield. The research primarily centers on the MutT4 enzyme from M. smegmatis, which was genetically modified to include a translational ramp sequence aimed at enhancing protein stability. Despite successful initial PCR reactions and Gibson Assembly, attempts to integrate the translational ramp sequence into the MutT4 plasmid were ultimately unsuccessful. However, optimal conditions for protein expression were determined through experiments involving temperature and IPTG concentration variations. The results indicated that a temperature of 28°C and IPTG concentration of 0.5 mM yielded the highest levels of MutT4 enzyme. Further attempts to improve expression through environmental factors such as metal-ion cofactors and pH adjustments were inconclusive. This project highlights the importance of optimizing both genetic constructs and environmental conditions to achieve high levels of protein expression in bacterial systems.
