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. A single-pulse X-ray exposure will completely destroy small individual crystals; therefore, fresh specimens must 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 1000pulses per second and will pose a new challenge: how to quickly determine successful crystal hits and avoid a high-rate data deluge. it has been argued that serial femtosecond crystallography (SFX) data from XFELs are de-facto radiation damage free 3–5.

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.

The Single Particles, Clusters, and Biomolecules & Serial Femtosecond Crystallography (SPB/SFX) instrument of the European XFEL is primarily concerned with three-dimensional diffractive imaging, and three-dimensional structure determination, of micrometre-scale and smaller objects, at atomic or near-atomic resolution. 2015-05-07 · Nevertheless, by applying the recently developed method of serial femtosecond crystallography with LCP as a growth and carrier matrix for delivering microcrystals (LCP-SFX) into an X-ray free-electron laser (XFEL) beam (Liu et al., 2013, Weierstall et al., 2014, Liu et al., 2014a), we successfully determined the room-temperature crystal structure of the human AT 1 R in complex with ZD7155 (AT 1 R-ZD7155). Serial femtosecond crystallography (SFX) [Chapman et al. (2011), Nature, 470, 73–77], based on the X‐ray free‐electron laser, is a new and powerful tool for structure analysis at atomic resolution. 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).

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. Here, we use serial femtosecond crystallography (SFX) at an X-ray free electron laser (XFEL) to identify the features governing the in vivo crystallization of Cyt1Aa in Bti cells, and to track the Serial femtosecond crystallography (SFX) represents a set of techniques developed to enable X-ray crystallography experiments at X-ray FELs, which encompasses multiple developments in sample introduction and data collection. Serial femtosecond crystallography with X-ray free electron lasers. X-ray free electron lasers (XFELs) have enabled biomolecular nano- and micro-crystallography at ambient temperatures by using extremely brief X-ray pulses (each only a few tens of femtoseconds) to outrun radiation damage, which is an inherent problem in bio-imaging techniques. 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.

In this example, an electrospun microjet (A, scale bar 150 μm) of a Serial femtosecond crystallography (SFX) using X-ray Free-Electron Lasers (XFELs) allows for room temperature protein structure determination without evidence of conventional radiation damage. In this method, a liquid suspension of protein microcrystals can be delivered to the X-ray beam in vacuum as a micro-jet, which replenishes the crystals at a rate that exceeds the current XFEL pulse Extracting structure-factor moduli from diffraction patterns of protein nanocrystals is one of the critical issues of serial femtosecond X-ray crystallography. Unlike a conventional crystallography experiment, serial femtosecond crystallography combines data from hundreds or thousands of crystals of varying size and quality, a situation reminiscent of powder diffraction.

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

X-ray free electron lasers (XFELs) have enabled biomolecular nano- and micro-crystallography at ambient temperatures by using extremely brief X-ray pulses (each only a few tens of femtoseconds) to outrun radiation damage, which is an inherent problem in bio-imaging techniques. 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. The extremely bright XFEL pulses enable data collection with microcrystals (ca. 50–1 μm). The advent of hard X-ray free-electron lasers has opened a new chapter in macromolecular crystallography.
