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

Protein-protein interactions mediate all fundamental cellular processes, yet the structural complexity of protein assemblies mean they are often difficult to characterise using traditional analytical methods. This project will develop and demonstrate novel mass spectrometric approaches towards a molecular level description of the structure and interactions of biological protein complexes, which in turn may underpin the rational design of drugs for the treatment of a range of human health conditions. This project will also provide training of young researchers to the highest international standards in mass spectrometry and protein science, for benefit to Australian industry and research.Read moreRead less

Australian Computational Molecular Science Network. Computational Molecular Science (CMS) involves the use of theory and computational methods to simulate and visualise molecular systems ranging from small atmospheric species to proteins, nucleic acids, chemical polymers and materials. It represents our most incisive expression of what we understand about the molecular basis of nature. The CMS network will integrate and cross-fertilize both fundamental and application-based expertize in molecula ....Australian Computational Molecular Science Network. Computational Molecular Science (CMS) involves the use of theory and computational methods to simulate and visualise molecular systems ranging from small atmospheric species to proteins, nucleic acids, chemical polymers and materials. It represents our most incisive expression of what we understand about the molecular basis of nature. The CMS network will integrate and cross-fertilize both fundamental and application-based expertize in molecular scale computations in the fields of nanoscience, biomaterials, biotechnology, biomedical science and environmental science. It will uncover and explore critical new interdisciplinary science and create new molecular-based paradigms that will drive advances in these fields over the next decade.Read moreRead less

The twenty first century is said to be the century of biology. And there is no doubt that the development of our understanding of biological system is continuing at a massive rate. However as our understanding deepens, we need to draw on the whole range of scientific disciplines to proceed. This Centre draws together a multidisciplinary team of world-leading scientists to address one the key questions in modern biology, the structure of a membrane protein. We will develop techniques based on the latest developments in theoretical physics & chemistry, imaging, biology and technology - including the new Australian Synchrotron - to create new approaches to structural biology.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
Joint Theoretical and Experimental Electron Momentum Spectroscopic Studies for DNA Bases. The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases.

The study of DNA structure is an area of intense research activity and continues to reveal new levels of complexity and diversity. Recent experiments (Science, 2002) provided direct evidences of the adenine non-planarity, indicating non-rigidity of DNA bases. Electron momentum spectroscopy (EMS) has been identified to be an appropriate technique in the study of chemical binding mechanism and orbitals at molecular level. The aims of the project is to study orbitals and interactions of DNA and RNA bases such as adenine, thymine (uracil), guanine and cytosine using momentum space quantum mechanics and EMS experimental techniques. The outcome of the project will improve our understanding of the DNA double helical strand structure.Read moreRead less
