Improved Support for XFEL/SFX Deposition


The OneDep system for deposition, validation, and biocuration recently extended the range of metadata collected for structures solved by X-ray Free-Electron Laser (XFEL) and Serial Femtosecond Crystallography (SFX). Depositors can now provide details of the sample delivery, data measurement details such as focusing optics, pulse energy, frequency, and number of crystals used in new PDBx/mmCIF categories dedicated to XFEL and SFX experiments.

Authors of existing XFEL entries in the PDB archive will be contacted to provide additional information for their entries.

RCSB PDB News ImageFrom PDB-101's Methods for Determining Atomic Structures: Structures of photoactive yellow protein were determined by serial femtosecond crystallography after illumination, capturing the isomerization of the chromophore after it absorbs light. Structures included in this movie include: 5hd3 (ground state), 5hdc (100-400 femtoseconds after illumination), 5hdd (800-1200 femtoseconds), 5hds (3 picoseconds), 4b9o (100 picoseconds), 5hd5 (200 nanoseconds) and 1ts0 (1 millisecond).
