CRYOGENIC TEMP XRAY DIFFRACTION SERIAL

Furthermore, UV-Vis absorption spectroscopy confirms that Dm(6-4)photolyase is photoactive in the crystals, giving a green light to time-resolved SFX studies on the protein, which can reveal the structural mechanism of the photoactivated protein in DNA repair.ĭepartment of Chemistry and Molecular Biology, University of Gothenburg, Box 462, 405 30 Gothenburg, Sweden. Practical course in Protein Crystallization and X-Ray Diffraction. The samples were imaged at a working distance of 5 mm using the BSE in-lens detector and a beam energy of 1.7 kV. The structures agree with each other, indicating that the structural information obtained from crystallography at cryogenic temperature also applies at room temperature. Intense femtosecond x-ray pulses produced at the Linac Coherent Light Source (LCLS) were used for simultaneous x-ray diffraction (XRD) and x-ray emission spectroscopy (XES) of microcrystals of photosystem II (PS II) at room temperature. The cryo-holder was placed in a Gemini 500 cryo-SEM at a temperature of 133.2 K with a vacuum pressure of 2.7 × 10 8 mbar. The cryogenic structure was solved to 1.79 Å resolution using conventional X-ray crystallography. The crystallization and preparation conditions are also reported.

The room-temperature structure was solved to 2.27 Å resolution and was obtained by serial femtosecond crystallography (SFX) using an X-ray free-electron laser. The anti-contaminator greatly reduces the buildup of ice layers on the specimen due to condensation of residual water vapor in the experimental vacuum chamber. Here, crystal structures of Drosophila melanogaster (6-4) photolyase at room and cryogenic temperatures are reported. We describe a liquid nitrogen-cooled anti-contamination device for cryogenic X-ray diffraction microscopy.

Their function is to repair DNA lesions using visible light. Dive into the research topics of New high- and low-temperature apparatus for synchrotron polycrystalline X-ray diffraction. 84, 093705 was constructed for X-ray diffraction imaging at cryogenic temperatures by. (6-4) photolyases are flavoproteins that belong to the photolyase/cryptochrome family. In a previous study, the diffraction apparatus KOTOBUKI-1 Nakasako et al.
