Self organization in (bio)molecular systems: Simulating the folding and aggregation of peptides, proteins and lipids. Molecular self-assembly is a basic property of living systems. Most proteins fold spontaneously and then further self-organize into functional complexes, effectively biological machines. Understanding how this occurs is a fundamental theoretical challenge with widespread application. Work will focus on developing methodology to simulate, computationally, the folding and aggrega ....Self organization in (bio)molecular systems: Simulating the folding and aggregation of peptides, proteins and lipids. Molecular self-assembly is a basic property of living systems. Most proteins fold spontaneously and then further self-organize into functional complexes, effectively biological machines. Understanding how this occurs is a fundamental theoretical challenge with widespread application. Work will focus on developing methodology to simulate, computationally, the folding and aggregation of peptides, proteins, and lipids. The aim is to accurately predict the structures of small peptides in solution and to refine crude models of larger molecules (complexes). This will facilitate the development of peptide based therapeutics and is essential in exploiting the growing volume of genetic information in biology and medicine.Read moreRead less
Structural studies of plant disease resistance proteins. Plant cells have evolved a gene-for-gene disease resistance mechanism, involving an interaction of a plant-derived receptor with a specific pathogen-derived molecule. Currently, plant breeders are restricted to the resistance genes available in particular crop species or sexually compatible relatives. In the last few years, several plant disease resistance genes have been identified, providing a foundation for studying the molecular basis ....Structural studies of plant disease resistance proteins. Plant cells have evolved a gene-for-gene disease resistance mechanism, involving an interaction of a plant-derived receptor with a specific pathogen-derived molecule. Currently, plant breeders are restricted to the resistance genes available in particular crop species or sexually compatible relatives. In the last few years, several plant disease resistance genes have been identified, providing a foundation for studying the molecular basis of the resistance process. We propose to obtain three-dimensional structural information on representative R proteins and their ligand complexes. This will form the basis for modifying existing resistance genes to confer resistance to new diseases, resulting in large economic benefits.Read moreRead less

Drug discovery is reliant on the application of basic research and advanced technologies to obtain solutions to human suffering caused by diseases. This application seeks funding to support the installation of state-of-the-art mass spectrometry instrumentation at Griffith University and the University of Melbourne. The requested instrumentation will enhance high quality collaborative research programs in drug discovery and eradicate significant deficiencies in research infrastructure at both institutions. Access to state-of-the-art mass spectrometry instrumentation will markedly improve our international competitiveness across a broad range of biological and chemical science disciplines.Read moreRead less
Molecular basis of the interaction between plant disease resistance proteins and pathogen avirulence proteins. Management of crop diseases involves the integrated use of resistant cultivars and the application of chemical pesticides. Many diseases, however, including rust, continue to pose an economically significant threat to agricultural productivity in Australia.

Management of crop diseases involves the integrated use of resistant cultivars and the application of chemical pesticides. Many diseases, however, including rust, continue to pose an economically significant threat to agricultural productivity in Australia. The research outlined in this proposal aims to understand the mechanisms, at a molecular and structural level, that enable resistant plants to detect and respond to pathogen attack. The outcomes of this currently unavailable fundamental understanding will enable new, durable and more effective resistance genes to be engineered. Therefore, the work has significant economic and environmental implications for agricultural crop plant productivity in this country.Read moreRead less
