Faculty of Science: Institution: Department of Chemistry and Molecular Biology ; Institutionen för kemi och molekylärbiologi: Parts of work: 1. Serial femtosecond crystallography is an emerging and promising method for determining protein structures, making use of the ultrafast and bright X-ray pulses from X-ray free-electron lasers. The upcoming X-ray laser sources will produce well above 1000 pulses per second and will pose a new challenge: how to quickly determine successful crystal hits and avoid a high-rate data deluge. Proposed BioXFEL 2015 HWI Crystallization Workshop - Petra Fromme, Ph.D. - June 2nd, 2015 Using femtosecond X-ray pulses from X-ray free-electron lasers (XFELs), serial femtosecond crystallography (SFX) offers a route to overcome radiation damage to small protein crystals via the “diffraction-before-destruction” approach.

The European X-ray Free-Electron Laser (FEL) became the first operational high-repetition-rate hard X-ray FEL with first lasing in May 2017. Biological structure determination has already benefitted from the unique properties and capabilities of X-ray FELs, predominantly through the development and application of serial crystallography.

We performed time-resolved serial femtosecond crystallographic analyses of ChR by using an X-ray free electron laser, which revealed conformational changes following photoactivation. By applying the recently developed method of serial femtosecond crystallography at an X-ray free-electron laser, we successfully determined the room-temperature crystal structure of the human AT 1 R in complex with its selective antagonist ZD7155 at 2.9-Å resolution. Serial femtosecond crystallography (SFX) using X-ray free-electron lasers (XFELs) can produce radiation-damage-free room-temperature structures. Ligand-binding studies using SFX have received only modest attention, partly owing to limited beamtime availability and the large quantity of sample that is required per structure determination.

The SACLA generates X-rays a billion times brighter than SPring-8. The extremely bright XFEL pulses enable data collection with microcrystals (ca. 50–1 μm). 2019-05-06 · Fixed-target serial femtosecond crystallography (FT-SFX) was an important advance in crystallography by dramatically reducing sample consumption, while maintaining the benefits of SFX for The Serial Femtosecond Crystallography (SFX) user consortium will design, build, and commission an experimental instrument at the European XFEL for high-throughput structure determination of (nano)crystalline biological macromolecular samples.

Thus, in this approach, which can be described as serial femtosecond rotation crystallography (SF-ROX) (Schlichting, 2015), the orientation of the crystal is known for each individual exposure and conventional processing programs can be used for data analysis.
