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. Such tr ....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. 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
Investigating the subunit interactions of a molecular protein import machine. The project will provide fundamental knowledge of how sophisticated natural molecular machines interact with their substrates in plants and animals. It will also provide the basis for training of students and personnel in a range of structural biology technologies including several that are not commonly used by biologists, but make use of two major facilities that have been invested in by our government, namely the Aus ....Investigating the subunit interactions of a molecular protein import machine.

Unravelling transthyretin amyloid, bounding ahead using wallabies. Each protein in our body has a unique shape that enables it to function correctly. For unknown reasons, some proteins can change their shape, aggregate with other proteins and stick to the outside of cells of major organs or nerves. This prevents those cells from working properly and results in disease. Transthyretin is a protein that changes shape and aggregates in the heart of most people over the age of 70. The disease is call ....Unravelling transthyretin amyloid, bounding ahead using wallabies. Each protein in our body has a unique shape that enables it to function correctly. For unknown reasons, some proteins can change their shape, aggregate with other proteins and stick to the outside of cells of major organs or nerves. This prevents those cells from working properly and results in disease. Transthyretin is a protein that changes shape and aggregates in the heart of most people over the age of 70. The disease is called Senile Systemic Amyloidosis (SSA). It is not known how or why this happens. There is no cure or therapy. This project will use transthyretins from human and wallaby to explore a possible cause of SSA. If our hypothesis is correct, we will propose preventative actions to reduce the incidence of SSA in the future.Read moreRead less
Molecular toxinology of Australia's lesser known venomous snakes. This proposal represents a tremendous opportunity for biodiscovery from venomous snakes. This will be achieved through the researchers' unique approach of investigating previously unmapped venom systems for divergent, bioactive proteins. An understanding of venomous animal protein evolution great potential in drug discovery and other commercial applications. This project will provide Australian graduate and post-graduate stude ....Molecular toxinology of Australia's lesser known venomous snakes. This proposal represents a tremendous opportunity for biodiscovery from venomous snakes. This will be achieved through the researchers' unique approach of investigating previously unmapped venom systems for divergent, bioactive proteins. An understanding of venomous animal protein evolution great potential in drug discovery and other commercial applications. This project will provide Australian graduate and post-graduate students with finely tuned skills in cutting edge methodological techniques and a fluent understanding of molecular evolution, preparing them to be internationally competitive scientists.Read moreRead less
Molecular-genetic organization and evolution of dinoflagellate mitochondria. Dinoflagellates are unicellular organisms that are important parts of the biota as significant primary producers of the oceans. Certain dinoflagellates form essential symbionts of reef-forming corals and loss of the symbiont causes coral bleaching and death, a phenomenon linked to global warming. Dinoflagellate blooms are also notorious for causing fish kills and human illnesses such as paralytic shellfish poisoning. My ....Molecular-genetic organization and evolution of dinoflagellate mitochondria. Dinoflagellates are unicellular organisms that are important parts of the biota as significant primary producers of the oceans. Certain dinoflagellates form essential symbionts of reef-forming corals and loss of the symbiont causes coral bleaching and death, a phenomenon linked to global warming. Dinoflagellate blooms are also notorious for causing fish kills and human illnesses such as paralytic shellfish poisoning. My studies of the mitochondrion will address a major aspect of the biology of this poorly understood group. Mitochondrial function is often a target for drugs and other controlling agents, and therefore these studies could offer scope to better interpret and manage dinoflagellates in our environment.Read moreRead less
