Revealing Protein Structures (IMAGE) Forschungszentrum Juelich Caption Observation of a typical protein crystal used to study molecular structures by crystallography. Left: as seen with the naked eye; in the center: model of the arrangement of proteins in a crystalline structure; Right: schematic representation of the movement of a protein by a few degrees inside a crystal, as observed through NMR spectroscopy and simulation of the molecular dynamics. Due to these movements, the protein structure that can be obtained via crystallography becomes "blurred". Credit Paul Schanda/CEA Usage Restrictions Please give credit.
