Oxidative protein folding of industrially and pharmaceutically important recombinant proteins

Oxidative protein folding (protein folding and disulphide bond formation) is important for function and stability of many proteins. Disulphide bond formation is one of the most common post-translational modifications found in proteins, which is catalysed by dedicated sulphydryl oxidoreductase systems in specialized cellular compartments (e.g. the ER, mitochondrial intermembrane space) in vivo. Moreover, misfolded disulphide bonds can be reduced (broken) and corrected by disulphide reductases and/or isomerases. Therefore, it is no supervise that oxidative folding of proteins in vitro is challenging and often a key problem of recombinant protein production. In this project, we are interested in study oxidative folding of industrially and pharmaceutically important recombinant proteins, for example, TGF-βs (Transforming Growth Factor beta), and how thiol/disulphide oxidoreductases such as Mia40-Erv1, PDI, and Trx systems affect the folding of these proteins in vitro. The project aims to enhance the oxidative refolding yields of industrially and pharmaceutically important proteins, as well as understanding protein folding mechanisms of the target proteins. The key techniques required for this project include protein expression and purification, protein folding and functional characterisations using electrophoresis, chromatography, and various spectroscopic methods. This project will provide an excellent opportunity for a self-motivated student to learn and develop many essential skills used in protein studies.
