The structure of a 33-protein, 1.5-MDa RNA polymerase II preinitiation complex (PIC) was determined by cryo-EM and image processing at a resolution of 6-11 Å. Atomic structures of over 50% of the mass were fitted into the electron density map in a manner consistent with protein-protein cross-links previously identified by mass spectrometry. The resulting… CONTINUE READING
