Serial crystallography on in vivo grown microcrystals using synchrotron radiation

open access: yesIUCrJ, 2014
Crystal structure determinations of biological macromolecules are limited by the availability of sufficiently sized crystals and by the fact that crystal quality deteriorates during data collection owing to radiation damage. Exploiting a micrometre-sized

Dose‐dependent structural and electron‐density features in the lytic polysaccharide monooxygenase NcAA9D

open access: yesActa Crystallographica Section D, Volume 82, Issue 8, Page 900-914, August 2026.
A series of 36 structures of the Neurospora crassa LPMO NcAA9D were refined against X‐ray crystal datasets collected with increasing dose from a single crystal to provide insights into dose‐dependent structural changes at the active site of the enzyme.

Recent results in time resolved serial femtosecond crystallography at XFELs

open access: yesCurrent Opinion in Structural Biology, 2020
Time-resolved serial femtosecond crystallography (tr-SFX) methods exploit slurries of crystalline samples that range in size from hundreds of nanometers to a few tens of micrometers, at near-physiological temperature and pressure, to generate atomic resolution models and probe authentic function with the same experiment. 'Dynamic structural biology' is

Convergent-beam attosecond x-ray crystallography

open access: yesStructural Dynamics
Sub-ångström spatial resolution of electron density coupled with sub-femtosecond to few-femtosecond temporal resolution is required to directly observe the dynamics of the electronic structure of a molecule after photoinitiation or some other ultrafast ...

Serial millisecond crystallography of membrane and soluble protein microcrystals using synchrotron radiation

open access: yesIUCrJ, 2017
Crystal structure determination of biological macromolecules using the novel technique of serial femtosecond crystallography (SFX) is severely limited by the scarcity of X-ray free-electron laser (XFEL) sources. However, recent and future upgrades render

Dose-resolved serial synchrotron and XFEL structures of radiation-sensitive metalloproteins

open access: yesIUCrJ, 2019
An approach is demonstrated to obtain, in a sample- and time-efficient manner, multiple dose-resolved crystal structures from room-temperature protein microcrystals using identical fixed-target supports at both synchrotrons and X-ray free-electron lasers

Hydroxyethyl cellulose matrix applied to serial crystallography

open access: yesScientific Reports, 2017
Serial femtosecond crystallography (SFX) allows structures of proteins to be determined at room temperature with minimal radiation damage. A highly viscous matrix acts as a crystal carrier for serial sample loading at a low flow rate that enables the ...
