Extremophilic organisms have the ability to survive at temperatures incompatible with human life. For unicellular organisms, this is driven by protein adaptation. Studying extremophilic proteins is important both for their applications (e.g. creating proteins better tuned for biotechnology and clinical use) but also can reveal fundamental understanding of the relationship between sequence, stability and function. While much is known about how proteins function at high temperature, little is known about adaptation to the cold.
In recent exciting work we showed that PB6 Csp B (a cold-shock protein isolated from an Antarctic bacterium) displays unexpected changes in its structure and dynamics when cooled to <20 ° C. This suggests a novel mechanism of adaptation to the cold. In this project you will use an array of biophysical methods to investigate how changes in temperature affect the structure, dynamics, binding affinity and catalytic rate of PB6 Csp B. Using directed evolution, you will identify the residues responsible for these effects, allowing the rational re-design for temperature dependence to the cold for the first time.
You should hold a first degree equivalent to at least a UK upper-second class honours degree or a MSc degree in a relevant subject.
