A bio-enabled synthesis for the glycopeptide antibiotics. This project aims to develop an in vitro biomimetic synthesis for glycopeptide antibiotics (GPAs) by combining peptide synthesis and crosslinking catalysed by biosynthetic Cytochrome P450 enzymes. The crosslinking step in GPA biosynthesis is essential for antibiotic activity but impedes their chemical synthesis. This project will study the in vitro behaviour and characteristics of the biosynthetic P450 enzymes. This will provide direct be ....A bio-enabled synthesis for the glycopeptide antibiotics. This project aims to develop an in vitro biomimetic synthesis for glycopeptide antibiotics (GPAs) by combining peptide synthesis and crosslinking catalysed by biosynthetic Cytochrome P450 enzymes. The crosslinking step in GPA biosynthesis is essential for antibiotic activity but impedes their chemical synthesis. This project will study the in vitro behaviour and characteristics of the biosynthetic P450 enzymes. This will provide direct benefits: the development of new glycopeptide antibiotic derivatives and the identification of new biocatalysts for complex chemical synthesis. Knowledge gained will also directly enable future reengineering of glycopeptide antibiotic production in vivo.Read moreRead less
Harnessing the potential of metals in biocatalysis. The project aims to use an integrated, multi-disciplinary approach to study the properties of a group of related but functionally diverse enzymes; binuclear metallohydrolases (BMHs). These enzymes are of great relevance to protein engineers aiming to produce potent agents for bioremediation and pharmacologists interested in developing drugs. Elucidating and modulating the mode of action of BMHs is thus our main objective and should provide esse ....Harnessing the potential of metals in biocatalysis. The project aims to use an integrated, multi-disciplinary approach to study the properties of a group of related but functionally diverse enzymes; binuclear metallohydrolases (BMHs). These enzymes are of great relevance to protein engineers aiming to produce potent agents for bioremediation and pharmacologists interested in developing drugs. Elucidating and modulating the mode of action of BMHs is thus our main objective and should provide essential information to fully exploit the potential of these enzymes for practical applications. In particular, understanding how metal ions interact with BMHs and how this contributes to their reactivity is crucial to optimally understand their biotechnological potential.Read moreRead less

Worldwide markets for biotechnology-derived products are projected to grow to at least $50 billion per year for the next 10 years. The cornerstone of biotechnology is the production of proteins. The applicant has discovered a new pathway for protein production in bacteria. The primary objective of this project is to use a diverse array of biochemical and biophysical techniques to understand how this new protein production platform works. We will also assess this new pathway for the production of proteins of interest to the biotechnology sector. This project expects to determine how this system can be exploited for use in the growing Australian bioeconomy.Read moreRead less
Nanoparticles to combat cellular dysfunction. This project aims to design, synthesise and characterise nanoparticles that can mediate the adverse effects of reactive oxygen species. The project expects to develop nanoparticles with tailored chemical functionality to modulate the concentration of reactive oxygen species and develop a platform technology for addressing conditions where reactive species are overproduced.

This project aims to design, synthesise and characterise nanoparticles that can mediate the adverse effects of reactive oxygen species. The project expects to develop nanoparticles with tailored chemical functionality to modulate the concentration of reactive oxygen species and develop a platform technology for addressing conditions where reactive species are overproduced. The project will research how nanoparticles’ physicochemical properties affect their activity, and how they affect cellular function, tissue morphology and particle transport in a biological milieu. The project is expected to benefit the advanced manufacturing, veterinary and medical sectors and could lead to new chemotherapeutics.Read moreRead less
Chiral Catalysts by Rational Design. This project aims to integrate theory and experiment to design new catalysts for the synthesis of multi-stereocentre-containing molecules. Such molecules offer clear advantages in the area of drug design, owing to their potent and selective binding to biological targets, but a lack of available methods for their preparation currently limits their widespread use. This project will use theory to guide the discovery of new ways to make these molecules. It is exp ....Chiral Catalysts by Rational Design.

Such molecules offer clear advantages in the area of drug design, owing to their potent and selective binding to biological targets, but a lack of available methods for their preparation currently limits their widespread use. This project will use theory to guide the discovery of new ways to make these molecules. It is expected that detailed understanding of the factors that control stereocentre formation will be obtained from accurate theoretical modelling and will be applied to invent new catalysts that deliver improved performance and control over product structure.Read moreRead less
