This cryo-EM renaissance was spurred by Agard and Chengs efforts to develop camera hardware and software capable of detecting single electrons a goal that had long been considered impractical by the field, but which the duo accomplished by bringing together scientists and engineers at UCSF, Lawrence Berkeley National Laboratory, and Gatan, a Pleasanton, Calif., company that makes EM cameras. A protein must fold into a native state or a range of three-dimensional states in order to carry out biological functions, and must retain a certain degree of flexibility to accommodate various chemistries and binding events.
