Summary
Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals. Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability ....Metal ions such as iron and copper have been reproted to be present in the lesions present in diseased human arteries and it has been suggested that these metal ions contribute to the development of atherosclerosis (hardening of the arteries) via their ability to catalyse the formation of highly reactive molecualr fragments called free radicals. Though metal ions are known to catalyse such reactions in test-tube experiments, both the presence of metal ions in diseased arteries and their ability to generate free radicals is controversial. This study will employ a novel, minimally-invasive, technique to assess the nature and quantity of metal ions present in well-defined human and animal lesions at different stages of lesion development. The ability of these metal ions to catalyse free radical formation from components present in the artery wall will also be assessed. The release of these metal ions from the artery wall to added organic molecules will be assessed as this might minimise their potential to cause damage, and provide a possible therapeutic strategy. These studies will therefore provide valuable information as to the significance and role of reactive metal ions in the development of human artery disease and the possible prevention, or minimisation, of such processes.Read moreRead less
An Open Source Approach to Understanding an Important Parasite Ion Pump. This project plans to synthesise new compounds that bind the protein ATP4, an essential ion pump in the malaria parasite. It plans to generate a three-dimensional map to understand how these compounds stop ATP4 from working. Several promising new medicines for malaria target ATP4, yet we do not understand properly how they do so. The project’s intended aims will be achieved using new methods in synthetic chemistry and membr ....An Open Source Approach to Understanding an Important Parasite Ion Pump.

Several promising new medicines for malaria target ATP4, yet we do not understand properly how they do so. The project’s intended aims will be achieved using new methods in synthetic chemistry and membrane biology, and by leveraging global scientific inputs through online research methods allowing anyone to participate.Read moreRead less

This project aims to use a Labcyte Echo 550 acoustic dispenser with Combination Software to deliver sophisticated assay-ready screening. The Echo is the only liquid handling dispenser for 1536-well microplates and will allow Australian researchers to develop assay miniaturisation. The robotics will provide our nation’s researchers with a distinct competitive edge by enhancing assay sophistication, accuracy and reproducibility while reducing cost. The expected benefits will advance the elucidation of molecular mechanisms involved in complex biological phenomena. The benefits of this are substantial, including reduction in test compound and reagents, which in turn reduces laboratory costs, conserves cells and increases data quality.Read moreRead less

This project aims to establish state-of-the-art complementary mass spectrometers to help research into molecular structure and interactions, post-translational modifications, compound stability and availability within complex biological samples. The facility’s complementary mass spectrometers combine high specificity with high sensitivity and ultrafast scanning, and are expected to rapidly discover, identify and characterise biomolecules including peptides, proteins and small molecules. The discovery of unknown compounds is expected to improve fundamental understanding of molecular structure and function, provide opportunities for new bio-industries in health and the environment, and generate commercial opportunities through spin-off companies, patents and licensing.Read moreRead less
Enzyme-Mediated Machining of Chelators to Bind and Recover Valuable Metals. Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture.

Metals are critical components of electronic devices and electrical products. Rapid disposal cycles create a major problem in managing e-waste metals and identifies an opportunity in the circular economy for recovery and re-use. Organic compounds that bind metal ions (chelators) are useful but could be improved to select a target metal from a mixture. This project aims to dissect a method used by bacteria to biosynthesize chelators and hijack this to bioengineer new classes of chelators. Outcomes include new chelators and advanced knowledge of metal selectivity, with potential environmental and economic benefits arising from recovery of valuable metals. The project will benefit chemical biology research training for real-world applications.Read moreRead less

The emerging convergence of nanoscience and photonics offers the opportunity of using light to interrogate nanoscale domains, providing unprecedentedly localised measurements. This will allow biological scientists to understand how single cells react to and communicate with their surroundings. This science will underpin a new generation of devices capable of probing the response of cells within individuals to environmental conditions or treatment, creating innovative and powerful new sensing platforms.Read moreRead less
