TLDR
The performance of the femtosecond crystallography method is demonstrated by determining a 1.9-Å radiation damage–free structure of bovine cytochrome c oxidase, a large (420-kDa), highly radiation-sensitive membrane protein.
Abstract
By combining the use of relatively large crystals and an X-ray free-electron laser, a radiation damage–free three-dimensional structure of a radiation-sensitive protein (bovine cytochrome oxidase) was solved at 1.9-A resolution. We report a method of femtosecond crystallography for solving radiation damage–free crystal structures of large proteins at sub-angstrom spatial resolution, using a large single crystal and the femtosecond pulses of an X-ray free-electron laser (XFEL). We demonstrated the performance of the method by determining a 1.9-A radiation damage–free structure of bovine cytochrome c oxidase, a large (420-kDa), highly radiation-sensitive membrane protein.

Native structure of photosystem II at 1.95 Å resolution viewed by femtosecond X-ray pulses.

TL;DR: A ‘radiation-damage-free’ structure of PSII from Thermosynechococcus vulcanus in the S1 state is reported, and it is expected that this structure will provide a blueprint for the design of artificial catalysts for water oxidation.
