Hydrogen-abstraction reactions are of vital importance in the chemical, biochemical and polymerization processes that occur in everyday life. The objective of the proposed research is to improve our understanding of such reactions. State-of-the-art quantum chemistry calculations will be used to examine a broad range of hydrogen-abstraction reactions, and to obtain accurate information about the factors that influence such reactions. Building on this work, more detailed case studies will be performed in two important areas: the hydrogen-abstraction steps in biochemical reactions mediated by coenzyme B12, and chain-transfer processes in conventional and controlled free-radical polymerization.Read moreRead less

theoretical techniques with the successful ongoing Australian experimental program in atom
lasers, atom chip interferometry and ultra-cold fermions. Pioneering theoretical methods in

Allosteric regulation, molecular structure and function of transglutaminase 2. With Australia's ageing population, we can expect to see increasing prevalence of pathologies such as cancer, Alzheimer's disease, and cataracts. The ubiquitous enzyme transglutaminase 2 (TG2) has been implicated in all of these age-related diseases, as well as in chronic disorders such as coeliac disease and diabetes, and may contribute in a positive way to wound healing.

With Australia's ageing population, we can expect to see increasing prevalence of pathologies such as cancer, Alzheimer's disease, and cataracts. The ubiquitous enzyme transglutaminase 2 (TG2) has been implicated in all of these age-related diseases, as well as in chronic disorders such as coeliac disease and diabetes, and may contribute in a positive way to wound healing. Understanding how TG2 is activated and inactivated, and how it selects its targets, will be a critical addition to current knowledge of this enzyme, and will be an essential prerequisite for the development of TG2-targetted drugs and other TG2-related therapies.Read moreRead less

First, it will enhance Australia's research capacity in the fields of organelle genomics and evolutionary biology. Second, it will yield highly skilled young researchers: a postdoctoral fellow (Shao), a PhD student and two BSc Honours students. Third, it will generate new knowledge about genome recombination in animal mitochondria. Recombination is a fundamental, yet poorly understood issue in mitochondrial genomics and evolutionary biology. Knowledge from this project will also improve our understanding of other important issues that are associated with animal mitochondria; like the mechanisms of mitochondrial disease and ageing, and the evolution of modern humans and other animals.Read moreRead less
