Serial femtosecond rotation crystallography: an opportunity for high-resolution crystal structure determination free from radiation damage. Radiation damage

Serial Femtosecond Crystallography Current crystallography methods require mesoscopic crystals that can take many years of research to obtain. We are currently developing a novel concept for structure determination, where single shot diffraction patterns are collected from a stream of nanocrystals, using femtosecond pulses from an X-ray Free Electron Laser (XFEL). 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. Since user operation started in 2012, we have been involved in the development of serial femtosecond crystallography (SFX) measurement systems using XFEL at the SACLA. The SACLA generates X-rays a billion times brighter than SPring-8.

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. Recent developments of serial femtosecond crystallography at X-ray free electron lasers combined with the use of membrane-mimetic gel-like matrix of lipidic cubic phase (LCP-SFX) for crystal growth and delivery hold significant promise to accelerate structural studies of membrane proteins. Serial femtosecond crystallography (SFX) data were recorded at the European X-ray free-electron laser facility (EuXFEL) with protein microcrystals delivered via a microscopic liquid jet. An XFEL beam striking such a jet may launch supersonic shock waves up the jet, compromising the oncoming sample. To investigate this efficiently, we employed a novel XFEL pulse pattern to nominally expose the 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.

The European XFEL (EuXFEL) is a 3.4-km long X-ray source, which produces femtosecond, ultrabrilliant and spatially coherent X-ray pulses at megahertz (MHz) repetition rates.

Serial femtosecond crystallography (SFX) using x-ray free-electron laser (XFEL) radiation is an emerging method for three-dimensional (3D) structure determination using crystals ranging from a few micrometers to a few hundred nanometers in size and potentially even smaller.

Since the invention of the first light bulb by Thomas Alva Edison in 1879, light sources have been the 2. Nanocrystallization and characterization. Because nanocrystals were previously seen as merely a 2019-11-18 · The single particles, clusters and biomolecules and serial femtosecond crystallography instrument of the European XFEL: initial installation.

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.
