Understanding prokaryotic small proteins from context. Prokaryotic small proteins are increasingly recognised to play important biological roles but have been largely overlooked due to the lack of adequate tools to study them. This project aims to develop new methods to identify and predict the functions of small proteins from microbial communities by studying sequence patterns in their genomes. These predicted functions will be confirmed in the laboratory, leading to a catalogue of newly charac ....Understanding prokaryotic small proteins from context. Prokaryotic small proteins are increasingly recognised to play important biological roles but have been largely overlooked due to the lack of adequate tools to study them. This project aims to develop new methods to identify and predict the functions of small proteins from microbial communities by studying sequence patterns in their genomes. These predicted functions will be confirmed in the laboratory, leading to a catalogue of newly characterised small proteins from a diverse range of habitats and geographies. By creating new ways to study the role of small proteins in the global microbiome, we will provide the foundational knowledge required to leverage these proteins for use in biotechnology.

Advances in Peptide Synthesis: Exploiting Underutilised Functional Groups. The translation of therapeutically-relevant classes of peptides to the clinic is often limited by chemists' ability to synthesise these complex biomolecules efficiently and sustainably. This project aims to develop new tools for the preparation of designer peptides that are broadly inspired by an underutilised reactive group found in naturally-occurring peptide sequences. Expected outcomes encompass health and economic be ....Advances in Peptide Synthesis: Exploiting Underutilised Functional Groups. The translation of therapeutically-relevant classes of peptides to the clinic is often limited by chemists' ability to synthesise these complex biomolecules efficiently and sustainably. This project aims to develop new tools for the preparation of designer peptides that are broadly inspired by an underutilised reactive group found in naturally-occurring peptide sequences. Expected outcomes encompass health and economic benefits for the Australian community, including: the first approach to a class of promising antibiotic peptide natural product analogues, the development of a mild electrochemical approach to peptide modification, and the production of a library of novel amino acids for incorporation into potential antibiotic leads.Read moreRead less
Defining a new family of sodium channel accessory proteins. Voltage-gated sodium channels are key proteins that function as multi-subunit complexes to regulate neuronal excitability. The project aims to investigate the structure and function of a novel family of accessory subunits by utilizing a class of toxins, derived from the giant Australian stinging tree, that directly binds to these proteins to modulate sodium channel function. The project aims to generate significant new knowledge on the ....Defining a new family of sodium channel accessory proteins.
