About Richard Neutze

Neutze’s group uses X-rays generated at synchrotrons and at X-ray free electron lasers to probe structural changes in membrane proteins. Membrane proteins are a very diverse class of proteins that control energy transduction and signalling processes in living organisms. By observing structural changes in membrane proteins we gain insight into how evolution has optimized them to perform chemical reactions essential for life. We have a strong history of international collaboration and we combine scientific questions with developing new methods to address these questions.

Neutze took his PhD in physics in 1995 from the University of Canterbury (New Zealand). He was introduced to the field of molecular biophysics by Janos Hajdu at Oxford University (England). Neutze accepted a Humboldt Fellowship in physics with Franz Hasselbäch at Tübingen University (Germany) before returning to molecular biophysics as a postdoc with Janos Hajdu at Uppsala University. In 1998 Neutze received an Assistant Professor grant from the Swedish Research Council. With this support Neutze relocated his group to Chalmers University of Technology in 2000. Six years later Neutze was appointed Professor of Biochemistry at the University of Gothenburg.

Important Publications

Photosynthetic reaction centres

Photosynthetic reaction centres harvest light to drive the charge-separation reactions that underpin photosynthesis, the major mechanism by which sunlight is converted into chemical energy in living cells. We have used time-resolved X-ray diffraction and time-resolved X-ray scattering to observe structural changes associated with these light-driven reactions.

Bacteriorhodopsin

Bacteriorhodopsin harvests light to pump protons across an energy transducing biological membrane, a second mechanism by which sunlight is converted into chemical energy in living cells. We have used time-resolved X-ray diffraction and low-temperature intermediate trapping to observe structural changes associated with these light-driven reactions.

Methodology developments using X-ray free electron lasers

X-ray free electron lasers were transformative technologies which increased the number of X-rays that could be focused onto a small-spot in a short time by a factor of a billion. We have pioneered new approaches utilizing these machines for structural studies of membrane proteins.

Structural studies of aquaporins

Aquaporins are membrane proteins that control the flow of water into and out of cells. We have used X-ray crystallography to reveal how the flow of water is regulated by eukaryotic aquaporins.
