These facilities will be the best instruments of their kind, and will enable researchers at Australian institutions to enhance the quality of their research and remain internationally competitive through the application of modern MCD spectroscopic techniques to the study of metal-centred biomolecules. These facilities will drive a number of programs in the area of metalloenzyme and photosystem II research.Read moreRead less
Molecular mechanisms of novel bacterial copper defense proteins. This project aims to reveal molecular and cellular mechanisms used by bacteria to neutralise the destructive effects of copper. Copper is an essential trace element in living systems. It is toxic to bacteria and so plays a vital role in nutritional immunity. To counteract copper toxicity, bacteria have evolved defense mechanisms. The project will investigate a novel but poorly understood class of bacterial proteins, the suppressor ....Molecular mechanisms of novel bacterial copper defense proteins. This project aims to reveal molecular and cellular mechanisms used by bacteria to neutralise the destructive effects of copper. Copper is an essential trace element in living systems. It is toxic to bacteria and so plays a vital role in nutritional immunity. To counteract copper toxicity, bacteria have evolved defense mechanisms. The project will investigate a novel but poorly understood class of bacterial proteins, the suppressor of copper sensitivity proteins, that contribute to this key virulence trait. The expected outcomes will be fundamental new knowledge of metallo-protein diversity, bacterial virulence mechanisms, and membrane protein function with potential impact on health, environment, and biotechnology.Read moreRead less

High-resolution electron microscopy (EM): Direct electron detection cameras are a recent technological breakthrough delivering one of the greatest single advancements to the field of molecular cryo-EM. The aim of this project is to enable a 'first of a kind' cryo-EM platform in Australia enabling high-throughput atomic resolution protein structure determination. This will be achieved by integrating a state-of-the-art Gatan K2 Summit Direct Electron Detection camera system into the established cryo-EM facility managed by the University of Queensland node of the Australian Microscopy and Microanalysis Facility. This will offer unique and significantly improved capabilities for atomic resolution protein structure analysis, and will support a broad range of projects across the biological sciences.Read moreRead less
