High Resolution EPR Spectroscopy - A Tool for Determining Electronic and Geometric Structure of Metalloenzymes. High resolution orientation selective pulsed EPR and END(T)OR in conjunction with computer simulation (XSophe) and computational chemistry will allow the determination of the electronic and geometric structure (distance and orientation of nuclei surrounding the metal ion(s)) of multiple redox centres in DMSOR, DorC and DMSDH to be determined. In addition pulsed ELDOR in conjunction wi ....High Resolution EPR Spectroscopy - A Tool for Determining Electronic and Geometric Structure of Metalloenzymes. High resolution orientation selective pulsed EPR and END(T)OR in conjunction with computer simulation (XSophe) and computational chemistry will allow the determination of the electronic and geometric structure (distance and orientation of nuclei surrounding the metal ion(s)) of multiple redox centres in DMSOR, DorC and DMSDH to be determined. In addition pulsed ELDOR in conjunction with molecular modelling will enable the mapping (distance and orientation) of redox centres in complex multicentered metalloproteins (DMSDH and DorC) and in protein-protein complexes (DMSOR-DorC) providing information on the pathway of electron transfer and hence the role of the pyranopterins.Read moreRead less
Cross-Entropy Methods in Complex Biological Systems. The Cross-Entropy method provides a powerful new way to find superior solutions to complicated optimisation problems in biology, ranging from better design and implementation of medical treatments to an increased understanding of complex ecosystems.
Spatio-temporal modelling of Ras dependent MAP kinase activation. This project is at the heart of the national research priority 'Frontier Technologies for Building and Transforming Australian Industries'. Using cutting edge methods and techniques of systems biology, coupled with innovative experimental molecular cell biology we will construct and simulate mathematical models of the EGF-regulated MAP kinase pathway. The project will yield new insights into the fundamental mechanisms of cell sign ....Spatio-temporal modelling of Ras dependent MAP kinase activation. This project is at the heart of the national research priority 'Frontier Technologies for Building and Transforming Australian Industries'. Using cutting edge methods and techniques of systems biology, coupled with innovative experimental molecular cell biology we will construct and simulate mathematical models of the EGF-regulated MAP kinase pathway. The project will yield new insights into the fundamental mechanisms of cell signal transduction that drive cell division, differentiation and transformation and may enable the design of new anticancer therapies. Importantly, the modelling and simulation methods developed in the project will have a general applicability to other complex systems such as sustainable ecological systems.Read moreRead less
Stochastic Modelling of Genetic Regulatory Networks: Subtitle - Genetic Regulation is a Noisy Business. The completion of the human genome marked the culmination of one hundred years of reductionist science in cell biology. Although further bioinformatics analysis will continue, the focus is shifting towards synthesis and understanding how the regulatory genetic components dynamically interact to form functional phenotypes. The key to this is the understanding of the roles of stochasticity in ....Stochastic Modelling of Genetic Regulatory Networks: Subtitle - Genetic Regulation is a Noisy Business. The completion of the human genome marked the culmination of one hundred years of reductionist science in cell biology. Although further bioinformatics analysis will continue, the focus is shifting towards synthesis and understanding how the regulatory genetic components dynamically interact to form functional phenotypes. The key to this is the understanding of the roles of stochasticity in cellular processes. This project will explore these roles and will develop an integrated complex systems modelling, simulation and visualisation framework. This will be used on an exemplar application for lineage commitment in haematopoiesis and for exploring and validating genetic regulatory models in general.Read moreRead less
