  • Researchers get a first look at the mechanics of membrane proteins

    University of Illinois biophysics professor Klaus Schulten, right, and postdoctoral researcher James Gumbart used cryo-EM images as well as detailed structural information about the ribosome and other molecules to construct an atom-by-atom model of the system that threads a growing protein into the cellular membrane.
