The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Summary
A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are prote ....A New Generation Biosensor and Fluorescence Facility for Proteomics. The complete DNA sequence (the genome) is now known for many organisms and advances are being made to identify the complement of messenger RNA (the transcriptome) and the resultant collection of proteins (the proteome). The genome is largely fixed while the transcriptome and proteome differ between cell types in an organism and constantly vary to adapt the cell to changing conditions. The mediators of these variations are proteins, interacting with each other and with signal molecules. The next frontier in molecular biology is to identify and quantify these protein interactions. Our two institutions have a very large cohort of biologists whose research on proteins would be greatly facilitated by the Biacore 3000 and the ISS K2.Read moreRead less
Understanding mechanistic and systemic regulation of protein prenyltransferases. The proposed research will expand our understanding of lipid-conjugating enzymes that are critical for a multitude of normal cellular functions. We seek to reveal the basic workings of cells and help to explain the development and complexity of signalling networks in eukaryotic evolution. The findings will enable us to explore and exploit the catalytic properties of these lipid-related enzymes for applications in bi ....Understanding mechanistic and systemic regulation of protein prenyltransferases.

We seek to reveal the basic workings of cells and help to explain the development and complexity of signalling networks in eukaryotic evolution. The findings will enable us to explore and exploit the catalytic properties of these lipid-related enzymes for applications in biotechnology. The ultimate aim is to create novel technologies for protein production, modification and analysis that will accelerate the pace of discovery in protein research, basic cell and organism biology, diagnostics, biotechnology and drug discovery.

The Australian Protease Network. Proteases are pivotal enzymes during birth, life, ageing and death of all organisms. Proteases regulate most physiological processes by controlling protein activation, synthesis and turnover and are essential for replication and spread of viruses, bacteria and parasites that cause infectious diseases. Blockbuster drugs and diagnostics already target a few proteases.

Proteases are pivotal enzymes during birth, life, ageing and death of all organisms. Proteases regulate most physiological processes by controlling protein activation, synthesis and turnover and are essential for replication and spread of viruses, bacteria and parasites that cause infectious diseases. Blockbuster drugs and diagnostics already target a few proteases. Australians have made innovative contributions individually to understanding and regulating these enzymes. However this initiative aims to network their efforts by value-adding to the current protease research through promoting national and international collaborations to improve our understanding of biology, and encourage exploitation of proteases/inhibitors/receptors for pharmaceutical and industrial applications.Read moreRead less

As new scientific tools they could be used to interrogate biological systems & implicate specific protein surfaces in biological/disease mechanisms. As leads to new medicines (pharmaceuticals, vaccines, diagnostics), they could offer new ways of impacting on infection, diseases of the aged, & preventative medicine (National Research Priorities). As new intellectual property, the technology has the potential to advance basic science at the chemistry-biology interface while providing new economic opportunities for Australia.Read moreRead less
BIOCATALYSTS MINED FROM CYTOCHROME P450 LIBRARIES: AN INNOVATIVE TOOL FOR ACCELERATING DRUG DEVELOPMENT. The cytochrome P450s (P450s) are a family of enzymes that are perhaps the most versatile biological catalysts known. DNA shuffling is an emerging technique that takes the genes encoding families of enzymes and creates libraries of catalysts with both improved and novel properties. We will obtain proof of concept that shuffled P450 libraries can be screened and optimized for use as biocatalys ....BIOCATALYSTS MINED FROM CYTOCHROME P450 LIBRARIES: AN INNOVATIVE TOOL FOR ACCELERATING DRUG DEVELOPMENT. The cytochrome P450s (P450s) are a family of enzymes that are perhaps the most versatile biological catalysts known. DNA shuffling is an emerging technique that takes the genes encoding families of enzymes and creates libraries of catalysts with both improved and novel properties. We will obtain proof of concept that shuffled P450 libraries can be screened and optimized for use as biocatalysts in drug development. The methodologies developed here will overcome two critical bottlenecks in current drug development: the optimisation and metabolic profiling of new drug candidates. This will yield important benefits in accelerating the optimisation and safety testing of drugs under development.Read moreRead less

Their production requires laborious, expensive, and time-consuming construction of transgenic organisms or cells. Alternatively, recombinant proteins can be produced in extracts prepared from cells or organisms. The aim of this proposal is to develop a new technology that will make cell-free production of recombinant proteins rapid, cheap, and scalable. This will advance Australia’s intellectual leadership in the area of biotechnology and will bring numerous economic benefits by accelerating pharmaceutical development. Read moreRead less
Development of new herbicides targeting enzymes involved in the biosynthesis of branched-chain amino acids. Modern agriculture is heavily reliant on the use of herbicides. An inevitable consequence of herbicide usage is that resistant weeds will develop. Therefore, there is a continuing need to develop new herbicides to kill these resistant species. Herbicides interact with vulnerable molecular targets in plants, such as photosynthesis or the biosynthesis of certain amino acids. This project wil ....Development of new herbicides targeting enzymes involved in the biosynthesis of branched-chain amino acids. Modern agriculture is heavily reliant on the use of herbicides. An inevitable consequence of herbicide usage is that resistant weeds will develop. Therefore, there is a continuing need to develop new herbicides to kill these resistant species. Herbicides interact with vulnerable molecular targets in plants, such as photosynthesis or the biosynthesis of certain amino acids. This project will attempt to develop new herbicides that act upon two molecular targets that are not exploited by herbicides that are used currently. We will design, synthesize and test a variety of new compounds as potential environmentally-benign herbicides.Read moreRead less

MOLECULAR BREEDING OF CYTOCHROME P450 ENZYMES. Cytochrome P450s are enzymes that catalyse an impressive array of oxidative transformations. However, there is little available data on how to modify their substrate specificity and generate tailored biocatalysts. We plan to use an emerging technology known as DNA shuffling to create libraries of P450s with varying activities. These will then be screened for enzymes that can catalyse the formation of indigo (a blue dye) and indirubin (a chemother ....MOLECULAR BREEDING OF CYTOCHROME P450 ENZYMES.

The enzymes that catalyse indigo formation will be useful in the production of coloured transgenic plants and those that produce indirubin will have a role in gene therapy.Read moreRead less
