Combining new synthetic biology tools to boost crop CO2 capture and growth. A solution for improving crop yield is to enhance the carbon dioxide fixation properties of the enzyme Rubisco whose inefficient activity often limits plant growth. This project makes use of new synthetic biology capabilities to artificially evolve Rubisco in the laboratory and select for new versions with improved performance. These beneficial changes will be introduced into crop Rubisco using targeted gene editing appr ....Combining new synthetic biology tools to boost crop CO2 capture and growth. A solution for improving crop yield is to enhance the carbon dioxide fixation properties of the enzyme Rubisco whose inefficient activity often limits plant growth. This project makes use of new synthetic biology capabilities to artificially evolve Rubisco in the laboratory and select for new versions with improved performance. These beneficial changes will be introduced into crop Rubisco using targeted gene editing approaches and the improvements in photosynthesis, growth and yield evaluated. This information will aid complimentary biotechnological efforts seeking to supercharge photosynthesis and help deliver the second Green Revolution needed to meet the improvement required in future agriculture productivity and resource use.Read moreRead less
Nano-reactors: Protein cages as reusable scaffolds for designer enzymes. This project aims to develop robust protein cages derived from the coats of viruses to contain heat-stable P450 enzymes, for use as specialised protein bio-catalysts in chemical industries. A valuable chemical precursor of renewable bio-plastics will be produced from seed oils by enzymes, reducing the use of fossil fuels. This synthetic biology approach combines biotechnology, nanotechnology and protein engineering to estab ....Nano-reactors: Protein cages as reusable scaffolds for designer enzymes. This project aims to develop robust protein cages derived from the coats of viruses to contain heat-stable P450 enzymes, for use as specialised protein bio-catalysts in chemical industries. A valuable chemical precursor of renewable bio-plastics will be produced from seed oils by enzymes, reducing the use of fossil fuels. This synthetic biology approach combines biotechnology, nanotechnology and protein engineering to establish a plant-based platform biotechnology for using enzymes as catalysts to make high-value molecules. The project aims to show how to engineer clean, sustainable chemistry in designer nano-environments. This should make synthetic processes more sustainable and enhance advanced chemical manufacturing in Australia.Read moreRead less
Novel chemoenzymatic synthesis and bioconjugation of peptides and proteins. This project aims to solve the critical difficulty of producing the complex peptide insulin and related insulin-like peptides (INSLs) and their analogues. The project will use unique, recyclable enzymes which ligate smaller peptide segments with extraordinary site and substrate selectivity. The expected outcome of the project is novel, cheaper and scalable, enzyme-mediated engineering of this critical class of peptides a ....Novel chemoenzymatic synthesis and bioconjugation of peptides and proteins.

Industrial biotechnology for the manufacture of alkaloid pharmaceuticals. Drugs that treat opioid dependence and overdose are increasingly needed but their manufacture is difficult, inefficient and expensive. This project aims to develop enzymatic N-demethylation as a simpler and more sustainable approach to the manufacture and modification of opioid antagonists, alkaloids and other drug targets. It will increase our understanding of enzymatic N-demethylation and address engineering and biotechn ....Industrial biotechnology for the manufacture of alkaloid pharmaceuticals. Drugs that treat opioid dependence and overdose are increasingly needed but their manufacture is difficult, inefficient and expensive. This project aims to develop enzymatic N-demethylation as a simpler and more sustainable approach to the manufacture and modification of opioid antagonists, alkaloids and other drug targets. It will increase our understanding of enzymatic N-demethylation and address engineering and biotechnology challenges to improve yield and product isolation and concentration. Improvements in drug manufacturing processes will assist drug affected communities and industry will benefit from value adding, greater market share and flexibility, increased innovation and de-risked processes and new products.

Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer an ....Algal direct-air CO2 capture through interfacial enzyme immobilisation . Capturing CO2 directly from the atmosphere is challenging due to inherently slow mass transfer kinetics. This project aims to overcome this using an enzyme that can rapidly solubilise CO2 from air into water, to produce algae. By engineering the enzyme immobilisation at the air-water interface, this project will activate and protect the enzymes, increasing their lifespan and reducing costs. By understanding mass transfer and enzyme activity in the interfacial immobilisation media, floating enzyme rafts can be developed for deployment over expansive areas, facilitating large-scale conversion of atmospheric CO2 into algae-derived fuels, feeds and chemicals.Read moreRead less
