Functional characterisation of poly-histidine triad proteins. This project aims to understand the role and function of a novel family of surface proteins produced by Streptococci. These so-called polyhistidine triad proteins are known to contribute to capacity to cause disease in animals and humans, but we need to know how they work, as they may be excellent targets for novel drugs or vaccines.
Novel perspectives on the function of AB5 toxin B subunits in pathogenic bacterial. AB5 toxins are produced by bacteria that cause important diseases in humans and livestock. This project tests the hypothesis that the components of the toxins responsible for binding to host cells and tissues also directly contribute to cellular damage, thereby providing a better understanding of how AB5 toxin-producing bacteria cause disease.
Host-pathogen interactions: the role of mimicry. The proposed research program, using a combination of structure and functional analysis will provide insight into the mechanism of nucleotide hydrolysis by the enzymes NTPDases. This study will not only improve our fundamental understanding of NTPDase action but could lead to the rational design of antimicrobials.
