Characterisation of a powerful molecular motor, the FtsK DNA translocase. The FtsK protein is a fast and powerful molecular motor, a pump that can, and does, move an entire bacterial chromosome. This project will uncover the detail of the mechanism used by this motor to convert the cell's chemical energy source Adenosine Triphosphate (ATP) into movement of DNA; revealing the molecular detail of a fast and powerful motor.
The control of elongation factor 2 and its role in the regulation of protein synthesis. Protein synthesis is a key process in living cells. The main stage, elongation, is regulated through phosphorylation of elongation factor eEF2 in response to hormones, amino acids and cellular energy status, via changes in the activity of eEF2 kinase. We will study how these conditions control eEF2 kinase by studying its phosphorylation and identifying new kinases that regulate it. We will explore the role of ....The control of elongation factor 2 and its role in the regulation of protein synthesis. Protein synthesis is a key process in living cells. The main stage, elongation, is regulated through phosphorylation of elongation factor eEF2 in response to hormones, amino acids and cellular energy status, via changes in the activity of eEF2 kinase. We will study how these conditions control eEF2 kinase by studying its phosphorylation and identifying new kinases that regulate it. We will explore the role of eEF2 in controlling protein synthesis, seek new substrates for eEF2 kinase and initiate work to elucidate the structure of this unusual enzyme. This will enhance, in a range of ways, fundamental understanding of cell physiology.Read moreRead less
Identification of functionally important autophosphorylation site(s) on ataxia telangiectasia and Rad 3 - related (ATR) protein kinase. The integrity of our genetic material must be maintained so that it can be passed on from one generation to the next and also to minimize the risk of cancer and other pathologies in an individual. There are multiple proteins involved in protecting our DNA including several enzymes that detect and signal DNA damage to a series of pathways involved in halting the ....Identification of functionally important autophosphorylation site(s) on ataxia telangiectasia and Rad 3 - related (ATR) protein kinase. The integrity of our genetic material must be maintained so that it can be passed on from one generation to the next and also to minimize the risk of cancer and other pathologies in an individual. There are multiple proteins involved in protecting our DNA including several enzymes that detect and signal DNA damage to a series of pathways involved in halting the passage of cells through the cell cycle so that repair can occur. This project studies the mechanism of action of one of these enzymes which will be of benefit in designing new compounds to fight disease. Read moreRead less

High-resolution electron microscopy (EM): Direct electron detection cameras are a recent technological breakthrough delivering one of the greatest single advancements to the field of molecular cryo-EM. The aim of this project is to enable a 'first of a kind' cryo-EM platform in Australia enabling high-throughput atomic resolution protein structure determination. This will be achieved by integrating a state-of-the-art Gatan K2 Summit Direct Electron Detection camera system into the established cryo-EM facility managed by the University of Queensland node of the Australian Microscopy and Microanalysis Facility. This will offer unique and significantly improved capabilities for atomic resolution protein structure analysis, and will support a broad range of projects across the biological sciences.Read moreRead less
Novel ultraviolet radiation filters from extreme environments. This project aims to exploit uncultured microorganisms to produce and characterise novel ultraviolet radiation-filter biosynthesis pathways. Current ultraviolet radiation-filtering compounds are toxic and persistent.

This project aims to exploit uncultured microorganisms to produce and characterise novel ultraviolet radiation-filter biosynthesis pathways. Current ultraviolet radiation-filtering compounds are toxic and persistent. There is a need for biodegradable, ultraviolet radiation filters that are safe for use across a variety of health and industrial applications. Over millions of years, the damaging effect of ultraviolet radiation has exerted selective pressure on organisms that has driven the evolutionary diversity of natural radiation-filtering compounds. This project expects to characterise and harness the microbial diversity of unique high ultraviolet radiation ecosystems via synthetic biology to produce industrially and pharmacologically useful ultraviolet radiation filters.Read moreRead less

Under the hood: single-molecule studies of multi-protein machines. Living cells are filled with complex protein machines that are responsible for the molecular processes supporting life. This project is aimed towards the development of physical tools that enable the study of these protein complexes at the level of single molecules. This project aims to study the protein machinery responsible for DNA replication, the process of duplicating genomic information before cell division. By making real-time single-molecule movies of the replication process, this project aims to unravel the molecular mechanisms of this important process and provide the knowledge required to understand disease mechanisms and catalyse drug development.Read moreRead less

How is molecular information passed between generations? This project aims to determine the mechanisms responsible for the inheritance of acquired traits. Sometimes the environment can have effects on the phenotype of not only the exposed individual, but also their children and grandchildren. While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens.

While it is clear that this can occur, what is not clear is the mechanism by which this happens and the frequency at which it happens. This project will combine use of the model organism Caenorhabditis elegans with biochemistry and structural biology to determine what the molecular mechanism is by which this "transgenerational epigenetic inheritance" occurs.Read moreRead less
