Engineering safer pastures for livestock. This project aims to develop subterranean clover with elevated condensed tannins in leaves. This important pasture legume is currently a bloat risk for cattle and sheep due to low condensed tannins and high soluble proteins. Bloat is a health issue that costs the Australian and New Zealand livestock industries over $200 million per annum. Condensed tannins can reduce bloat, decrease methane production and improve efficiency of production. A novel approac ....Engineering safer pastures for livestock. This project aims to develop subterranean clover with elevated condensed tannins in leaves. This important pasture legume is currently a bloat risk for cattle and sheep due to low condensed tannins and high soluble proteins. Bloat is a health issue that costs the Australian and New Zealand livestock industries over $200 million per annum. Condensed tannins can reduce bloat, decrease methane production and improve efficiency of production. A novel approach using CRISPR and other innovative molecular techniques will generate breeding lines high in condensed tannins and deliver knowledge applicable to other pasture legumes. Expected outcomes for livestock producers include improved animal welfare, reduced carbon emissions and enhanced profits.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. While a peptide’s functionality can be extended with unnatural amino acids, the methods for their site-sele ....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. 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
