Profile

Biography

Research in my group seeks to understand the relationship between protein function, structure and dynamics, with a particular focus on metal-containing enzymes, enzymes in biotechnology and heme sensor proteins. We work in close collaboration with scientists at synchrotron radiation and XFEL facilities in the field of structural biology method development. A major current interest is in serial crystallography at XFEL and synchrotron beamlines including SACLA (Japan) and Diamond Light Source. We apply this to produce room temperature structures of radiation sensitive proteins free of the effects of radiation damage. We are studying time-resolved structural biology by this approach. Our work also encompasses protein bochemistry, molecular biology and a range of biophysical approaches.

Research and professional activities

Research interests

Serial crystallography using XFEL and synchrotron radiation

We use the latest X-ray free electron laser (XFEL) facilities including SACLA in Japan to produce crystal structures of metalloproteins without the effects of radiation damage that can compromise interpretation of structures determined by conventional synchrotron X-ray crystallography. We particularly apply this method to high valent states of Fe and Cu proteins relevant to enzyme mechanisms and to pursue time-resolved structural biology.

X-ray crystallography of Metalloproteins

We determine high resolution X-ray crystal structures of metalloproteins to establish their functional mechanisms. We combine this with single crystal spectroscopy of the crystals to validate redox and ligand states in the structures.

Key words: Structural Biology
Open to supervise

MSOX Crystallography

We are developing a new method to determine sequences of crystal structures of metalloproteins, where the X-rays used to determine structures are also used to drive redox reactions within those crystals to access catalytic intermediate states. This is combined with advanced computational simulation of the enzymes (quantum mechanics and molecular dynamics) and single crystal spectroscopies to fully characterise such mechanisms.

Cytochromes and Gas Sensors

We are characterising the interaction of nitric oxide and carbon monoxide to cytochromes c', proteins which are analogous to mammalian gas sensors involved in vasodilation. This work combines structural biology, kinetics and spectroscopy.

Development of genetic probes based on GFP for non-invasive detection and quantification of reactive oxygen species and antioxidants in subcellular compartments

Fluorescent protein biosensors are showing great promise in allowing the real time, spatial and quantitative detection of specific small molecules in living cells. We have engineered and used these biosensors in cells of the leaf to detect hydrogen peroxide, glutathione, lipid peroxides, oxidised ascorbate (vitamin C) and changes in pH. The detection spatially in real time has allowed us to develop a new hypothesis on the spatial dependency of signalling from chloroplasts to the nucleus in leaves exposed to high light - only those chloroplast in contact with the nucleus are capable of triggering a change in gene expression in response to high light. We have provided evidence, using these biosensors, that hydrogen peroxide is the mobile signal that transfers directly to the nucleus from connected chloroplasts. This work has led to further developments in biosensor technology in my laboratory, which in collaboration with colleagues in the School is beginning to extend our detection capability to animals cells and for studying other important signalling molecules.
