Manipulation of mitochondrial function by Legionella pneumophila. . The intracellular bacterial pathogen Legionella pneumophila co-evolved with eukaryotic hosts and has developed sophisticated mechanisms to manipulate human cell function – mitochondria in particular – by secreting >300 effector proteins through a specialised Type-IV system into the host cell. This research aims to understand the function of effector proteins targeted to mitochondria; delivering important new knowledge in host-pa ....Manipulation of mitochondrial function by Legionella pneumophila. . The intracellular bacterial pathogen Legionella pneumophila co-evolved with eukaryotic hosts and has developed sophisticated mechanisms to manipulate human cell function – mitochondria in particular – by secreting >300 effector proteins through a specialised Type-IV system into the host cell. This research aims to understand the function of effector proteins targeted to mitochondria; delivering important new knowledge in host-pathogen and mitochondrial biology and advanced cell biology tools. With most of the effector proteins yet to be characterised, benefits from the project will be to reveal specifically how these target mitochondria, and more broadly, how bacterial pathogens manipulate organelles for their survival.Read moreRead less
Characterising O-linked glycosylation across Burkholderia. Protein glycosylation, the chemical addition of sugars to proteins, enables the augmentation of protein properties. Across the Burkholderia genus we have shown O-linked glycosylation is both conserved as well as essential for bacterial fitness. Yet, we have little understanding of how glycosylation modulates the proteome of this genus. This project aims to characterise the glycoproteomes of Burkholderia species and track the impact of gl ....Characterising O-linked glycosylation across Burkholderia. Protein glycosylation, the chemical addition of sugars to proteins, enables the augmentation of protein properties. Across the Burkholderia genus we have shown O-linked glycosylation is both conserved as well as essential for bacterial fitness. Yet, we have little understanding of how glycosylation modulates the proteome of this genus. This project aims to characterise the glycoproteomes of Burkholderia species and track the impact of glycosylation on both the proteome and protein stability. By understanding how glycosylation shapes the proteome we will gain a greater understanding of the role of bacterial glycosylation in Burkholderia physiology as well as how we may better utilise microbial glycosylation for glycoprotein production.Read moreRead less
How does glycosylation shape protein function within Burkholderia? Protein glycosylation, the chemical addition of sugars to proteins, is an important but poorly understood aspect of bacterial physiology. This project aims to build on our recent discovery of the conservation of O-linked glycosylation across the Burkholderia genus to understand the function of this modification. Using cutting-edge proteomics, novel expression systems and molecular approaches this project will reveal the role of g ....How does glycosylation shape protein function within Burkholderia?

Using cutting-edge proteomics, novel expression systems and molecular approaches this project will reveal the role of glycosylation in Burkholderia species. This innovative project will provide a comprehensive understanding of how glycosylation contributes to Burkholderia protein function and how these systems can be harnessed for the creation of bespoke glycoconjugatesRead moreRead less
Elucidating the determinants of cation import across the kingdoms of life. The metal ion manganese is essential to all forms of life. This project aims to investigate how this poorly abundant cation is selectively acquired from the chemical complexity of the environment for import into cells by using state-of-the-art biochemical and microbiological techniques. This project expects to define the fundamental basis for how bacterial, archaeal and eukaryotic plastid cation-selective importers can di ....Elucidating the determinants of cation import across the kingdoms of life. The metal ion manganese is essential to all forms of life. This project aims to investigate how this poorly abundant cation is selectively acquired from the chemical complexity of the environment for import into cells by using state-of-the-art biochemical and microbiological techniques. This project expects to define the fundamental basis for how bacterial, archaeal and eukaryotic plastid cation-selective importers can discriminate manganese from chemical similar cations to achieve selective uptake. The expected outcomes of this work will be an understanding of the fundamental basis for selective metal import in biological systems. This should provide benefits for industry through synthetic biological applications of this knowledge. Read moreRead less
Bacterial vesicles transport their bioactive cargo to the host nucleus. This project aims to investigate how bacterial membrane vesicles transport their cargo to the nucleus of cells and its impact on host cell functions. Bacteria use membrane vesicles as a means of communication with the host, but the full extent of their effects on host cells has yet to be fully elucidated. This project expects to generate new knowledge in the field using cutting-edge imaging and molecular biology approaches. ....Bacterial vesicles transport their bioactive cargo to the host nucleus.
