Evolution, structure and function of key components in a molecular machine. The project will provide the basis for training of students and personnel in the previously recognized priority "Genomes-Phenomes", still the central theme of modern biology. In particular,
collaborations established with the Los Alamos National Laboratory in New Mexico will transfer to Australia expertise in the cutting edge discipline of small angle scattering for analysis of biologically important molecules.

collaborations established with the Los Alamos National Laboratory in New Mexico will transfer to Australia expertise in the cutting edge discipline of small angle scattering for analysis of biologically important molecules. Such training is essential for developing a future pool of skilled Australian scientists to staff and utilise the major national infrastructure developments represented by the Replacement Research Reactor and Australian Synchrotron, as outlined in the National Research Priority "Frontier Technologies".Read moreRead less

Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that ....Design and evaluation of new environmentally-benign herbicides that inhibit branched-chain amino acid biosynthesis. Herbicides interfere with processes that occur in plants, such as photosynthesis or the biosynthesis of certain amino acids. In this project we will focus on branched-chain amino acid biosynthesis, designing and evaluating inhibitors of the first two enzymes in this process. Based on their three dimensional structures we will develop an understanding of the molecular features that contribute to a potent inhibitor and those that are required for it to be effective upon plants. Using this information we will design and synthesis new compounds as potential environmentally-benign herbicides.Read moreRead less
Streamlining the dynamin epilepsy drug pipeline. Epilepsy affects up to one percent of Australia's population, yet one in three fail to respond to current medications. Our results will greatly impact on development of future epilepsy therapy. Identification of a new target for epileptic will allow better drug design to improve the potency of our lead drugs. This holds hope that new generation drugs will be more effective. The drugs are predicted to have fewer complications and side-effects. Th ....Streamlining the dynamin epilepsy drug pipeline.

Identification of a new target for epileptic will allow better drug design to improve the potency of our lead drugs. This holds hope that new generation drugs will be more effective. The drugs are predicted to have fewer complications and side-effects. The outcome has the potential to vastly improve prospects for up to 200,000 Australians. Intellectual property (IP) retained in Australia will generate future biotechnology industry. The novel chemical biological approaches will facilitate training of future generations of Australian scientists.Read moreRead less

It will build up our expertise in x-ray optics and synchrotron technology, and will open up a new approach to x-ray imaging and structure determination.
This will revolutionize our understanding of cellular and sub-cellular organisation with implications for the treatment of disease while the ability to determine structures of membrane proteins will open the door to fresh opportunities in rational drug design and biotechnology that will promote innovation in this industry, and the likely foundation of new start-up companies.Read moreRead less
Targeting mitochondrial dysfunction in disease. Defects in mitochondria, the energy producing compartments within cells, lead to severe neurodegenerative diseases and contribute to the development of cancer. Treatment for such diseases caused by mutations in mitochondrial DNA remains unsatisfactory and mostly confined to supportive measures. The identification of proteins that regulate gene expression within mitochondria provides an unexplored resource of potential disease modulators and drug ta ....Targeting mitochondrial dysfunction in disease.

Treatment for such diseases caused by mutations in mitochondrial DNA remains unsatisfactory and mostly confined to supportive measures. The identification of proteins that regulate gene expression within mitochondria provides an unexplored resource of potential disease modulators and drug targets. This research will lead to new strategies in the design of improved anticancer drugs, which is an important Australian research priority that will promote and maintain good health, and provide potential commercial outcomes.Read moreRead less
