Novel mechanisms of bacterial arsenic metabolism - arsenate reduction and arsenite oxidation. Novel arsenic metabolising bacteria (i.e., arsenate respiring and arsenite oxidising), which are both phylogenetically and physiologically unique, have been isolated from arsenic-contaminated areas in Australia. The arsenate respiring bacterium, Chrysiogenes arsenatis, is of particular interest as it is the only organism reported able to respire with arsenate using the respiratory substrate acetate as t ....Novel mechanisms of bacterial arsenic metabolism - arsenate reduction and arsenite oxidation. Novel arsenic metabolising bacteria (i.e., arsenate respiring and arsenite oxidising), which are both phylogenetically and physiologically unique, have been isolated from arsenic-contaminated areas in Australia. The arsenate respiring bacterium, Chrysiogenes arsenatis, is of particular interest as it is the only organism reported able to respire with arsenate using the respiratory substrate acetate as the electron donor. It is proposed that physiological, biochemical and molecular biological studies be carried out to better understand the mechanisms by which these organisms metabolise arsenic. The knowledge gained from these studies will have worldwide application in the development of an arsenic bioremediation system.Read moreRead less
Design and engineering of proteins for biotechnology and biomedicine. The primary aim of this application is to enhance the thermodynamic and folding properties of proteins by redesign and engineering. The structures and folding behaviour of the redesigned proteins will be characterised using X-ray crystallography and biophysical techniques. The expected outcomes of this project are: engineering of new proteins that can be used in biotechnology, medical and pharmaceutical applications, or basic ....Design and engineering of proteins for biotechnology and biomedicine. The primary aim of this application is to enhance the thermodynamic and folding properties of proteins by redesign and engineering. The structures and folding behaviour of the redesigned proteins will be characterised using X-ray crystallography and biophysical techniques. The expected outcomes of this project are: engineering of new proteins that can be used in biotechnology, medical and pharmaceutical applications, or basic research; fundamental insights into protein design and engineering; and a wealth of knowledge on the factors that dictate protein stability and folding.Read moreRead less
