Development and application of new peptide ligation methods for the synthesis and structure-function studies of glycoproteins. Novel synthetic technologies will be developed in this project to facilitate the preparation of glycoproteins, which are of widespread biological and therapeutic interest. These methods will enable the preparation of pure glycoproteins for detailed biochemical and functional studies eventually leading to therapeutic and diagnostic applications.
Functional studies of tyrosine sulfation using synthetic sulfoproteins. This project aims to address a lack of knowledge about how post-translational sulfation of tyrosine residues influences protein function. The project will develop a synthetic platform for the rapid and efficient generation of libraries of site-selectively sulfated proteins. The new methods will be used to study bioactive sulfated proteins secreted by ticks that dampen the inflammatory response and prevent blood from clotting ....Functional studies of tyrosine sulfation using synthetic sulfoproteins. This project aims to address a lack of knowledge about how post-translational sulfation of tyrosine residues influences protein function. The project will develop a synthetic platform for the rapid and efficient generation of libraries of site-selectively sulfated proteins. The new methods will be used to study bioactive sulfated proteins secreted by ticks that dampen the inflammatory response and prevent blood from clotting. Underpinned by the ability to access synthetic sulfoproteins, expected outcomes include a detailed understanding of how tyrosine sulfation can modulate function and stability of antibodies and proteins with anticoagulant and anti-inflammatory activities. Significant benefits of the project will include breakthrough technologies for the preparation of homogeneously modified proteins, which will strengthen Australia’s growing biotechnology sector.Read moreRead less

The goal of this project is to develop laser scanning confocal endomicroscopy as a tool for basic scientific discovery and rapid detection of disease biomarkers. The cutting-edge instrument and associated technologies will provide scientists with unprecedented access to dynamic biological processes as they occur in real-time. In addition, it will enable the development of virtual biopsies and instant diagnosis without the need for costly and time-consuming histopathological reports. Thus, it will not only drive transformative research but also transform health care delivery. It will also be a major boost to the Australian biotechnology industry with potential for enormous economic benefits.Read moreRead less
New methods for the chemical synthesis of a library of glycopeptide-based tri-component cancer vaccines. A novel method for the synthesis of tumour-associated glycopeptides will be developed in this research as well as the preparation of a library of glycopeptide-based cancer vaccines. These vaccines will be tested in immunological studies with a view to elucidating new immune-based therapies for the treatment of cancer.

Summary
Development of Innovative Chemical Tools for Studying Glycosyltransferases . This project aims to develop chemical probes capable of selectively binding and inhibiting two classes of carbohydrate processing enzymes known as O-linked beta-N-acetylglucosamine transferase and sialyltransferases. These enzymes are overexpressed in various cancers and play critical roles in cancer progression. Probes will be developed to analyse the activities of these enzymes in cancer cells.

Molecular Interactions with an antibiotic target in DNA replication. This project aims to develop and use new technologies to address mechanistic aspects of anti-bacterial compounds in development, and of the development of resistance to them. The project will focus on the sliding clamp subunit of the bacterial replicative polymerase by studying its association with many other proteins in vitro and in vivo, using novel techniques in solid-state NMR, single-molecule fluorescence and molecular mic ....Molecular Interactions with an antibiotic target in DNA replication. This project aims to develop and use new technologies to address mechanistic aspects of anti-bacterial compounds in development, and of the development of resistance to them. The project will focus on the sliding clamp subunit of the bacterial replicative polymerase by studying its association with many other proteins in vitro and in vivo, using novel techniques in solid-state NMR, single-molecule fluorescence and molecular microbiology. The outcomes are expected to be an increased understanding of bacterial DNA replication and mechanisms of antibiotic action and resistance. This project expects to generate new knowledge to assist in combatting antibiotic resistance in Gram-negative bacterial pathogens.Read moreRead less

This project aims to introduce strained alkenes as probes for cysteine sulfenic acid, a poorly understood biomarker for oxidative stress. This probe will enable rapid detection of cysteine sulfenic acid and meet an urgent need for tools to map cysteine redox signalling. Moreover, since many enzymes feature a cysteine sulfenic acid at their active site, the strained alkene probes will also serve as useful inhibitor probes of these enzymes. Such inhibitor probes will provide critical information for potential therapeutic applications in human conditions associated with oxidative stress such as ageing, cancer, and heart disease.Read moreRead less
