Protein degradation in mammals. One mechanism by which the regulation of protein turnover occurs is the balance between the activity of enzymes responsible for the ubiquitination and deubiquitination of target proteins. The majority of targets of this second family of enzymes are unknown. This project proposes a method for the identification of the targets of two specific mammalian deubiquitinating enzymes in order to understand their function and to begin to explore this new research field. ....Protein degradation in mammals.

This project proposes a method for the identification of the targets of two specific mammalian deubiquitinating enzymes in order to understand their function and to begin to explore this new research field. Knowledge about this new aspect of protein degradation could provide a powerful tool to test the effect of the stabilisation or removal of specific proteins in the cell and also to develop new technologies in protein production.Read moreRead less
The metabolic and enzymatic regulation of C4 photosynthesis and its impact on photosynthetic productivity. Australia's tropical pastures are dominated by plants utilising the C4 photosynthetic pathway. World wide C4 grasslands contribute to approximately 20% of global primary productivity. C4 plants also include important crop species such as maize, sorghum and sugar cane and are considered ideal species for bio-fuel production. This project will use a novel functional genomic/metabolomics appro ....The metabolic and enzymatic regulation of C4 photosynthesis and its impact on photosynthetic productivity. Australia's tropical pastures are dominated by plants utilising the C4 photosynthetic pathway. World wide C4 grasslands contribute to approximately 20% of global primary productivity. C4 plants also include important crop species such as maize, sorghum and sugar cane and are considered ideal species for bio-fuel production. This project will use a novel functional genomic/metabolomics approach to provide fundamental insights into the biochemical regulation of C4 photosynthesis under different environmental conditions. This will aid in the development of mathematical models of C4 photosynthesis required in climate models of CO2 exchange and enhance our ability to improve photosynthetic performance of agricultural species.Read moreRead less
