X-ray Diffraction Microscope. The results of the research will substantially expand Australia's knowledge base in the area of diffraction, imaging and structural biology. 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.

The results of the research will substantially expand Australia's knowledge base in the area of diffraction, imaging and structural biology. 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
Functional Dissection of the Bacterial Replisome. We now have the complete sequences of genes in humans and many other organisms, but we know much less about how the protein products of the genes communicate with each other to create and grow cells. Australia has recently invested heavily in state-of-the-art instruments that can be used to tackle these problems. This project will involve close interaction of four laboratories to use new instruments to determine how a large assembly of proteins i ....Functional Dissection of the Bacterial Replisome. We now have the complete sequences of genes in humans and many other organisms, but we know much less about how the protein products of the genes communicate with each other to create and grow cells. Australia has recently invested heavily in state-of-the-art instruments that can be used to tackle these problems. This project will involve close interaction of four laboratories to use new instruments to determine how a large assembly of proteins interact in a biological machine that makes DNA. This process occurs in similar ways in all organisms, and is essential for life. Understanding how DNA is made will help scientists to develop new antibacterial drugs, and learn how to make practical use of molecular machines that imitate biology.Read moreRead less
Nuclear magnetic resonance (NMR) studies of complex cellular responses: isotopomer sub-spaces, 'lost' ATP and 'tunable' anisotropy. Red blood cells (RBCs) transport oxygen around the body but they have other roles that are mediated by complex interconnecting metabolic pathways that generate myriad metabolites including ATP. A longstanding conundrum is the inability to account for ~60% of ATP turnover in human RBCs. Processes that may consume this 'lost' ATP, include autonomous motion of the cel ....Nuclear magnetic resonance (NMR) studies of complex cellular responses: isotopomer sub-spaces, 'lost' ATP and 'tunable' anisotropy. Red blood cells (RBCs) transport oxygen around the body but they have other roles that are mediated by complex interconnecting metabolic pathways that generate myriad metabolites including ATP. A longstanding conundrum is the inability to account for ~60% of ATP turnover in human RBCs. Processes that may consume this 'lost' ATP, include autonomous motion of the cell membrane called 'flickering', and maintenance of the biconcave-disc shape. NMR spectroscopy of quadrupolar nuclei in chiral aligned media, and isotopomer analysis will be used to define the kinetics of metabolism and membrane processes and thus help define the molecular basis of major blood disorders.

NMR Spectroscopy of Complex Cellular Processes. The Theme is the cell viewed as a complex regulated molecular assembly. The Aim is to establish an integrated mathematical model of red cell metabolism, membrane transport, shape, and mechanical properties, principally by using NMR spectroscopy. The Significance will be discovery of new aspects of cellular structure and function, and new NMR theory for molecular bioscience. Outcomes will include new NMR measurements of kinetics of metabolic reactio ....NMR Spectroscopy of Complex Cellular Processes. The Theme is the cell viewed as a complex regulated molecular assembly. The Aim is to establish an integrated mathematical model of red cell metabolism, membrane transport, shape, and mechanical properties, principally by using NMR spectroscopy. The Significance will be discovery of new aspects of cellular structure and function, and new NMR theory for molecular bioscience. Outcomes will include new NMR measurements of kinetics of metabolic reactions, rates of membrane transport, solute diffusion, and functions of key membrane- and cytoskeletal proteins. Practical applications will include strategies for modelling complex biochemical systems, and circumventing metabolic defects arising from inheritance, the environment, and therapies.Read moreRead less

This will be Australia's first dedicated five-dimensional multiphoton-microscopy platform, allowing observation of dynamic structures across different length and time scales under controlled temperatures, followed by high-resolution electron microscopy studies on the same samples. This platform will provide a unique characterisation tool to Australia's top-flight investigators, and so contribute to the nation's research priorities. It will enable: fundamental studies of cancer, neural diseases and immune disorders; the development of frontier technologies, such as smart nanomaterials, biosensors and targeted drug delivery; and applied research to help plants and soils adapt to climate variability, and to increase sustainable use of water.Read moreRead less

High-resolution imaging of live cells and tissue. Understanding the machinery of life and developing technologies that support life's processes requires biological and physical scientists and engineers to monitor molecular events in living systems. The aim is to take advantage of very recent developments in light microscopy to enable the non-invasive imaging of live cells and tissue at a previously unreachable level of detail.

Significant advances in research areas including vascular research, cancer, immunology, cell and molecular biology, functional genomics, biotechnology, nanotechnology and material engineering will be of major benefit both nationally and globally.Read moreRead less
Studies of the Dynamic Language of Bio-Molecular Communication and Signalling. For normal biological function, a multitude of external signals must be interpreted and responded to by cells. The responses must be carefully regulated and coordinated, or else pathological conditions will develop and, if not corrected, lead to uncontrolled proliferation or cell death. This project studies the mechanisms by which cells transmit signals. Proteins accomplish this communication by modifying the inter ....Studies of the Dynamic Language of Bio-Molecular Communication and Signalling. For normal biological function, a multitude of external signals must be interpreted and responded to by cells. The responses must be carefully regulated and coordinated, or else pathological conditions will develop and, if not corrected, lead to uncontrolled proliferation or cell death. This project studies the mechanisms by which cells transmit signals. Proteins accomplish this communication by modifying the interactions among their functional domains, effectively creating a conformational language. Knowledge of this language will impact biomedicine through its contributions to understanding the molecular pathology of diseased states, and biotechnology by enhancing our ability to use biological processes for applications.Read moreRead less
Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work ....Single Molecule Studies of Replisomal Function.

This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work and simultaneously measure the very small forces that the machines generate. This will give Australian scientists access to a new technology for studying molecular machines.Read moreRead less
