Retrieving high-resolution information from disordered 2D crystals by single-particle cryo-EM

Henning Paul-Julius Stahlberg

Electron crystallography can reveal the structure of membrane proteins within 2D crystals under close-to-native conditions. High-resolution structural information can only be reached if crystals are perfectly flat and highly ordered. In practice, such crys ...
