The major research focus of my group is the transport of proteins by the twin arginine protein transport pathway. This pathway, which is found in the cytoplasmic membranes of most bacteria, and the thylakoid membranes of plant chloroplasts, is highly unusual because it transports pre-folded proteins. Protein substrates are targeted to the Tat machinery by N-terminal signal peptides that contain an S/T- R-R-x-F-L-K 'twin arginine' motif. Our aims are to study the function and mechanism of the Tat protein transporter, and the contribution that it makes to the physiology of bacteria.

The Gram-positive bacterium Staphylococcus aureus uses an unusual Type VII secretion system to secrete possible virulence factors. In a collaboration with Professor Bill Hunter we have been structurally and biochemically characterising components and substrates of this system.
