High number of X-ray pulses per second reduces time needed for the study of biological structures.
Just days before the first anniversary of the start of European XFEL user operation, the first results based on research performed at the facility have been published. In the journal Nature Communications, the scientists, headed by Prof. Ilme Schlichting from Max-Planck-Institute for Medical Research in Heidelberg, Germany, together with colleagues from Rutgers State University of New Jersey, USA, France, DESY and European XFEL, describe their work using the intense X-ray laser beam to determine the 3D structure of several proteins. They demonstrate, for the first time that, under the conditions used at the time of the experiment an increased number of X-ray pulses per second as produced by the European XFEL can be successfully used to determine the structure of biomolecules. As much faster data collection is therefore possible, the time needed for an experiment could be significantly shortened. The detailed determination of the 3D structure of biomolecules is crucial for providing insights into informing the development of novel drugs to treat diseases.
Prof. Ilme Schlichting said: “Our work shows that under the conditions used data can be collected at European XFEL at a rate much faster than has ever been previously possible. As the time and cost of experiments decrease, very soon many more researchers will be able to perform experiments at high repetition rate X-ray lasers. Our results are therefore of interest not only tor the fields of biology and medicine, but also physics, chemistry and other disciplines.”
