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
Mass Spectrometric Investigations of Conformation and Dynamics of Biological Complexes. The new collaboration between the leading mass spectrometry groups at University Wollongong and Cambridge University will benefit both partners. Researchers at Wollongong will have access to an ion mobility mass spectrometry technology not currently available in Australia that will contribute to our understanding of complicated cellular processes such as chromosome replication.

The new collaboration between the leading mass spectrometry groups at University Wollongong and Cambridge University will benefit both partners. Researchers at Wollongong will have access to an ion mobility mass spectrometry technology not currently available in Australia that will contribute to our understanding of complicated cellular processes such as chromosome replication. The researchers' experience with this technology will pave the way for introduction of the technology to Australia and benefit the wider scientific community in wide-ranging projects such as development of new antibiotics and vaccines. Students from both institutions will benefit from experiencing science from an international perspective.Read moreRead less
Mapping Protein Contacts and Conformational Changes in Macromolecular Assemblies. We now have a great deal of information about the structures of proteins that interact to do much of the chemistry that governs the lives of cells and organisms, but are just beginning to understand how proteins communicate with each other in the large, dynamic molecular machines that carry out many cellular functions. Australia has invested in expensive instrumentation that can be used in conjunction with new labo ....Mapping Protein Contacts and Conformational Changes in Macromolecular Assemblies. We now have a great deal of information about the structures of proteins that interact to do much of the chemistry that governs the lives of cells and organisms, but are just beginning to understand how proteins communicate with each other in the large, dynamic molecular machines that carry out many cellular functions. Australia has invested in expensive instrumentation that can be used in conjunction with new laboratory methods to develop better understanding of how these machines work, and how they malfunction in disease. This project will bring together four scientists with a unique combination of expertise and novel technologies to develop understanding of changes in structure of a large protein complex in different functional states.Read moreRead less
ARC Centre of Excellence - Coherent X-ray Science. 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.

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

Summary
Membrane Protein Structure and Interaction Facility. While it is estimated that a third of the human genome encodes for membrane proteins, the structures of only relatively few membrane proteins are currently known. It will be some time before membrane protein structure determination becomes routine, yet over 50% of the drugs on the market today rely on the activity of membrane proteins for their efficacy. This application seeks to establish a Membrane Protein Structure and Interaction Facility ....Membrane Protein Structure and Interaction Facility. While it is estimated that a third of the human genome encodes for membrane proteins, the structures of only relatively few membrane proteins are currently known. It will be some time before membrane protein structure determination becomes routine, yet over 50% of the drugs on the market today rely on the activity of membrane proteins for their efficacy. This application seeks to establish a Membrane Protein Structure and Interaction Facility for the development and application of novel techniques and approaches to study the structure and interactions of membrane proteins. Research progress will be greatly enhanced by the establishment of this dedicated facility with cutting-edge technologies for the study of membrane proteins.Read moreRead less
Membrane interactions and neurotoxicity of Amyloid Abeta peptides from Alzheimer's disease. A consequence of the increase in human life span is that age-related neurodegenerative diseases such as Alzheimer's disease (AD) are more prevalent. Currently there are limited therapeutic treatments and no cure for AD. The key protein causing AD is Abeta and characterization of the toxic species of this peptide is critical towards identifying potential therapeutic targets. This proposal aims to study mut ....Membrane interactions and neurotoxicity of Amyloid Abeta peptides from Alzheimer's disease. A consequence of the increase in human life span is that age-related neurodegenerative diseases such as Alzheimer's disease (AD) are more prevalent. Currently there are limited therapeutic treatments and no cure for AD. The key protein causing AD is Abeta and characterization of the toxic species of this peptide is critical towards identifying potential therapeutic targets. This proposal aims to study mutant peptides made synthetically and to identify a membrane-binding site. By establishing which lipid is critically involved in membrane binding of Abeta and mediating subsequent cell death, drugs may be developed to prevent the binding of Abeta to membranes resulting in neuronal survival and prevention of memory loss in AD patients.Read moreRead less
Membrane structure and lipid interactions of the pore-forming toxin Equinatoxin II by NMR. The structure of Equinatoxin II, a pore-forming protein, will be determined in model cell membranes using solid-state NMR spectroscopy. The relationship of molecular structure to bioactivity and the nature of the pore-forming mechanism of this toxin will be determined. The results will aid in understanding how toxins lyse cells and could lead to the design of improved antibiotic peptides. Currently the st ....Membrane structure and lipid interactions of the pore-forming toxin Equinatoxin II by NMR.

The relationship of molecular structure to bioactivity and the nature of the pore-forming mechanism of this toxin will be determined. The results will aid in understanding how toxins lyse cells and could lead to the design of improved antibiotic peptides. Currently the structure of membrane proteins are difficult to determine and the newly developed techniques used for the structural determination of this membrane-associated protein will be suitable for studying other membrane proteins and receptors of pharmaceutical importance.Read moreRead less
