Production of complex biologics: Host capacity analysis and capability engineering
This project will utilise next generation synthetic biology regulatory tools, to enhance the production and secretion of complex multimeric protein-based biologics from bacterial hosts. RNA-based regulatory tools (riboswitches) have been developed that control gene expression at the level of translation initiation [1-3]. Previously we have used these tools to match our biotechnological demand to host cell synthetic capacity, for example matching expression rates to secretion capacity and inner membrane protein biogenesis allowing enhanced periplasmic secretion and production of recombinant inner membrane protein . This PhD project will seek to co-express and secrete commercially and clinically important multimeric protein-based biologics, such as F(abs), F(ab’)2, and T-cell receptors. This project will provide training in cutting-edge biotechnology, namely synthetic biology enabled host engineering, stress response engineering, and bio-processing engineering important for future careers in both academic and industrial R&D.
