  • Coherent diffraction of single Rice Dwarf Virus particles using soft X-rays at the Linac Coherent Light Source

    • Single particle imaging using X-ray Free Electron Lasers has recently made major advancements that have facilitated experiments on smaller samples compared to the earliest reported works on giant viruses and cells. Here, the technique was used to image the 70 nm Rice dwarf virus, for which the generated dataset is described here. The virus particles were aerosolized and injected into the X-ray beam of the Linac Coherent Light Source. A total number of 36534 diffraction patterns were recorded, of which approximately 10 % were classified as ‘single hits’ by the RedFlamingo software. With the anticipation to advance method development, the dataset along with usage instructions are deposited in the Coherent X-ray imaging data bank, free to access and analyze.

  • Megahertz serial crystallography

    • The new European X-ray Free-Electron Laser is the first X-ray free-electron laser capable of delivering X-ray pulses with a megahertz inter-pulse spacing, more than four orders of magnitude higher than previously possible. However, to date, it has been unclear whether it would indeed be possible to measure high-quality diffraction data at megahertz pulse repetition rates. Here, we show that high-quality structures can indeed be obtained using currently available operating conditions at the European XFEL. We present two complete data sets, one from the well-known model system lysozyme and the other from a so far unknown complex of a beta-lactamase from K. pneumoniae involved in antibiotic resistance. This result opens up megahertz serial femtosecond crystallography (SFX) as a tool for reliable structure determination, substrate screening and the efficient measurement of the evolution and dynamics of molecular structures using megahertz repetition rate pulses available at this new class of X-ray laser source.
