NELF-C loses its interaction with the RPB1 trigger loop in the poised state (front view). Models from map A showing paused NELF-C, funnel helices, and bridge helix are overlaid on top of model from map C showing poised NELF-C and PDB:6GMLshowing the trigger loop. Colors correspond to those shown in (B). Trigger loop is dark green.
