Laws of attraction and repulsion: a novel family of bacterial chemo-sensors

点击翻译按钮获取中文摘要

This project aims to reveal the structural basis for the abilities of a newly characterised, widespread family of chemotaxis receptors to sense and distinguish between attractants and repellents. Many bacteria are motile. Controlling the movement of bacterial populations requires understanding of their chemosensory mechanisms. It is anticipated that this work will generate significant new knowledge in the field of signalling biology that will drive the discovery of novel chemo-effectors and the redesign of receptor specificity. Innovative use of this knowledge could be the development of new classes of repellents that are not toxic. These could be used as a means to prevent infections caused by bacterial build-up on implanted medical devices.
