Description: Serial femtosecond crystallography using ultrashort pulses from x-ray free electron lasers (XFELs) enables studies of the light-triggered dynamics of biomolecules. We used microcrystals of photoactive yellow protein (a bacterial blue light photoreceptor) as a model system and obtained high-resolution, time-resolved difference electron density maps of excellent quality with strong features; these allowed the determination of structures of reaction intermediates to a resolution of 1.6 angstroms. Our results open the way to the study of reversible and nonreversible biological reactions on time scales as short as femtoseconds under conditions that maximize the extent of reaction initiation throughout the crystal.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4361027/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4361027/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tenboer, Jason -- Basu, Shibom -- Zatsepin, Nadia -- Pande, Kanupriya -- Milathianaki, Despina -- Frank, Matthias -- Hunter, Mark -- Boutet, Sebastien -- Williams, Garth J -- Koglin, Jason E -- Oberthuer, Dominik -- Heymann, Michael -- Kupitz, Christopher -- Conrad, Chelsie -- Coe, Jesse -- Roy-Chowdhury, Shatabdi -- Weierstall, Uwe -- James, Daniel -- Wang, Dingjie -- Grant, Thomas -- Barty, Anton -- Yefanov, Oleksandr -- Scales, Jennifer -- Gati, Cornelius -- Seuring, Carolin -- Srajer, Vukica -- Henning, Robert -- Schwander, Peter -- Fromme, Raimund -- Ourmazd, Abbas -- Moffat, Keith -- Van Thor, Jasper J -- Spence, John C H -- Fromme, Petra -- Chapman, Henry N -- Schmidt, Marius -- P41 GM103543/GM/NIGMS NIH HHS/ -- R01GM095583/GM/NIGMS NIH HHS/ -- R24 GM111072/GM/NIGMS NIH HHS/ -- R24GM111072/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Dec 5;346(6214):1242-6. doi: 10.1126/science.1259357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Physics Department, University of Wisconsin, Milwaukee, WI 53211, USA. ; Department of Chemistry and Biochemistry, Arizona State University, Tempe, AZ 85287, USA. ; Department of Physics, Arizona State University, Tempe, AZ 85287, USA. ; Linac Coherent Light Source, SLAC National Accelerator Laboratory, Sand Hill Road, Menlo Park, CA 94025, USA. ; Lawrence Livermore National Laboratory, Livermore, CA 94550, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany. ; Center for Free Electron Laser Science, Deutsches Elektronen Synchrotron DESY, Notkestrasse 85, 22607 Hamburg, Germany. ; Hauptman-Woodward Institute, State University of New York at Buffalo, 700 Ellicott Street, Buffalo, NY 14203, USA. ; Centre for Ultrafast Imaging, University of Hamburg, 22761 Hamburg, Germany.
