Serial protein crystallography in an electron microscope [PDF]

Nature Communications, 2019
Abstract Serial X-ray crystallography at free-electron lasers allows to solve biomolecular structures from sub-micron-sized crystals. However, beam time at these facilities is scarce, and involved sample delivery techniques are required.

Asymmetry in serial femtosecond crystallography data [PDF]

Acta Crystallographica Section A Foundations and Advances, 2017
Serial crystallography is an increasingly important approach to protein crystallography that exploits both X-ray free-electron laser (XFEL) and synchrotron radiation. Serial crystallography recovers complete X-ray diffraction data by processing and merging diffraction images from thousands of randomly oriented non-uniform microcrystals, of which all ...

Whole-pattern fitting technique in serial femtosecond nanocrystallography

IUCrJ, 2016
Serial femtosecond X-ray crystallography (SFX) has created new opportunities in the field of structural analysis of protein nanocrystals. The intensity and timescale characteristics of the X-ray free-electron laser sources used in SFX experiments ...

Complementarity of neutron, XFEL and synchrotron crystallography for defining the structures of metalloenzymes at room temperature

IUCrJ, 2022
Room-temperature macromolecular crystallography allows protein structures to be determined under close-to-physiological conditions, permits dynamic freedom in protein motions and enables time-resolved studies.

Droplet streams for serial crystallography of proteins

Experiments in Fluids, 2007
Serial diffraction of proteins requires an injection method to deliver protein molecules - preferably uncharged, fully hydrated, spatially oriented, and with high flux - into the crossed beams of an alignment laser and a focused probe beam of electrons or X-rays of typically only a few tens of microns diameter.

Serial Room Temperature Crystal Loading, Data Collection, and Data Processing of Human Glutaminase C in Complex with Allosteric Inhibitors

Bio-Protocol, 2022
Cancer cells often overexpress glutaminase enzymes, in particular glutaminase C (GAC). GAC resides in the mitochondria and catalyzes the hydrolysis of glutamine to glutamate.

Serial Femtosecond Crystallography of Membrane Proteins [PDF]

, 2016
Membrane proteins, including G protein-coupled receptors (GPCRs), constitute the most important drug targets. The increasing number of targets requires new structural information, which has proven tremendously challenging due to the difficulties in growing diffraction-quality crystals.

Serial millisecond crystallography for routine room-temperature structure determination at synchrotrons

Nature Communications, 2017
Serial crystallography was developed for protein crystal data collection with X-ray free-electron lasers. Here the authors present several examples which show that serial crystallography using high-viscosity injectors can also be routinely employed for ...

Serial snapshot crystallography for materials science with SwissFEL     [PDF]

Acta Crystallographica Section A Foundations and Advances, 2015
New opportunities for studying (sub)microcrystalline materials with small unit cells, both organic and inorganic, will open up when the X-ray free electron laser (XFEL) presently being constructed in Switzerland (SwissFEL) comes online in 2017. Our synchrotron-based experiments mimicking the 4%-energy-bandpass mode of the SwissFEL beam show that it ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
