Ein internationales Forscherteam hat erstmals die innere Struktur eines Biomoleküls hochaufgelöst mit einem Röntgenlaser analysiert. Die Studie an der Linac Coherent Light Source (LCLS) des US-Beschleunigerzentrums SLAC demonstriere das enorme Potenzial sogenannter Freie-Elektronen-Laser (FEL) für die Strukturbiologie, schreiben die Wissenschaftler im US-Fachjournal "Science". Das internationale Team, darunter Forscher vom Center for Free-Electron Laser Science (CFEL) auf dem DESY-Campus in Hamburg, entzifferte die Struktur des Enzyms Lysozym aus dem Hühnereiweiß auf 0,19 Nanometer genau. Lysozym ist ein extrem gut untersuchtes Biomolekül, das in der aktuellen Studie als Modellsystem diente, um die Genauigkeit der Methode zu belegen, wie die Forscher um Sébastien Oqaktc sxu SSDE dmgmgvg.
