Exploiting bacterial metal resistance machinery for metal ion nano-biosensors development. This project aims to integrate advanced materials chemistry, molecular biology, bio-electrochemical and synchrotron imaging approaches to understand the role of silver resistance machinery of bacteria in their ability to form silver nanoparticles.

This project aims to integrate advanced materials chemistry, molecular biology, bio-electrochemical and synchrotron imaging approaches to understand the role of silver resistance machinery of bacteria in their ability to form silver nanoparticles. This aims to enable discovery of new metal-specific reductase enzymes. The fundamental biomolecular understanding of bacterial silver resistance will allow the use of a silver-binding protein to develop a series of next-generation nano-biosensors. These biosensing platforms will provide high-throughput, cost-effective, selective, sensitive and continuous monitoring of heavy metal ions in effluents from mining and mineral processing industries in a real-time fashion.Read moreRead less
The role of copper in the early ubiquitination pathway. This project aims to explore the role of copper in ageing and protein turnover. The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system. It proposes ....The role of copper in the early ubiquitination pathway. This project aims to explore the role of copper in ageing and protein turnover. The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system. It proposes to characterise the structure and function of a newly identified copper-dependent form of cell enzyme which could be involved in amplifying ubiquitin-tagged protein breakdown. Copper is essential for life in all domains. Identifying copper as a major regulator in protein clearance is important in understanding this fundamental biological machinery.Read moreRead less
