Recombinant proteins are used as vaccines, drugs, and research tools, as well as food and detergent additives, comprising a A$100 billion international market. 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

This project aims to advance a waste gas fermentation process to enable the production of sustainable aviation fuel molecules for the first time. LanzaTech are world leaders in microbial gas fermentation and have produced ethanol at large scale in China. This project aims to combine the LanzaTech process with systems biology expertise at The University of Queensland to go beyond ethanol to deliver new value-added products such as butanediol and farnesene. To achieve this aim the project will explore, understand and overcome fundamental energy and metabolic limitations in the production microorganism. Achieving the aims will be of direct relevance to SkyNRG and the new Brisbane Bioport on their path to deliver sustainable fuel to Brisbane Airport.Read moreRead less

A flexible virus-like particle delivery platform for next-generation vaccines. Murine polyomavirus (MPyV) capsid proteins self-assemble into spherical protein shells approximately 45 nm in diameter. Such virus-like particles (VLPs) are of considerable interest as bionanotechnological tools.

Murine polyomavirus (MPyV) capsid proteins self-assemble into spherical protein shells approximately 45 nm in diameter. Such virus-like particles (VLPs) are of considerable interest as bionanotechnological tools. The unique flexibility provided by MPyV VLPs will be exploited by exploring the ability of the interior cavity to retain bioactive cargos while engineering novel functionality on the exterior surface by 'mix-and-match' assembly of VLPs from modified components. As a proof of concept for next-generation vaccines that stimulate much needed, broadly protective responses against infectious diseases, model antigens will be delivered to specific immune cells using this nano-container.Read moreRead less
Ancestral enzyme engineering for designer fat products. Consumers are increasingly turning to plant-based alternatives of meat and dairy products due to concerns about health, animal welfare and sustainability.

Consumers are increasingly turning to plant-based alternatives of meat and dairy products due to concerns about health, animal welfare and sustainability. Taste, nutritional profile, protein content and limited variety are barriers that continue to challenge food manufacturers. This project aims to develop a process for the fermentation of specialty food oils and fats from agriculture production waste, that can deliver the flavour and nutritional benefits of meat and dairy products when added to plant-based alternatives. The outcomes should valorise existing agriculture and food waste, converting waste materials into valuable food ingredients.Read moreRead less

Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors w ....Protein biosensors for detecting smoke exposure of grapes. Bush fires and controlled burns that take place in the vicinity of vineyards can lead to grape contamination with tasteless phenolic glucosides. Their hydrolysis during wine making leads to “smoke taint” – an unpleasant medicinal taste that can render wine undrinkable. We will apply a combination of organic synthesis, protein engineering and directed evolution to develop protein-based biosensors of phenolic glucosides. These biosensors will be used to devise a simple portable colorimetric test that can be performed in the vineyard or the winery. The ability to rapidly determine the level of grape contamination with phenolic glucosides would give Australian wine growers and wine makers a powerful tool to mitigate the effects of bushfires.Read moreRead less
In vitro expression of macrocyclic peptides. This project aims to develop a novel strategy for the production of polypeptides with unnatural chemical groups using a sense codon reassignment approach. Novel peptides could be used in a range of pharmaceutical applications. Peptides made of 20 natural amino acids cover only a very small fraction of the available chemical and functional space.

This project aims to develop a novel strategy for the production of polypeptides with unnatural chemical groups using a sense codon reassignment approach. Novel peptides could be used in a range of pharmaceutical applications. Peptides made of 20 natural amino acids cover only a very small fraction of the available chemical and functional space. While a peptide’s functionality can be extended with unnatural amino acids, the methods for their site-selective incorporation are inefficient. The project’s strategy relies on the depletion of selected tRNAs from an in vitro protein translation system and their replacement with synthetic tRNAs, charged with unnatural amino acids. It is expected that the developed technology could be used to rapidly generate and screen highly diversified macrocyclic peptide libraries.Read moreRead less
Genetic code expansion of a eukaryotic in vitro translation system. The genetic code programs biosynthesis of polypeptides with efficiency vastly superior to chemical engineering. As the chemical diversity of natural amino acids in proteins is limited, finding ways to include “unnatural” amino acids can supercharge biology with a range of new protein activities. While the genetic code can be expanded to make space for unnatural amino acids, the rarity of free codons and reliance on prokaryotic ....Genetic code expansion of a eukaryotic in vitro translation system. The genetic code programs biosynthesis of polypeptides with efficiency vastly superior to chemical engineering. As the chemical diversity of natural amino acids in proteins is limited, finding ways to include “unnatural” amino acids can supercharge biology with a range of new protein activities. While the genetic code can be expanded to make space for unnatural amino acids, the rarity of free codons and reliance on prokaryotic organisms limit the applicability of this approach. We will develop a new higher-organism cell-free protein production system that can incorporate multiple unnatural amino acids into defined points of proteins. This, enabling and broadly applicable technology, will be tested by constructing opioid biosensors.Read moreRead less
