a, An isosurface representation of the cryo-EM density with crucial structural elements labeled. The color code of the individual factors is identical to that of Figs. 2 and 3. b, A similar isosurface representation to a, overlaid with a 20-Å lowpass-filtered density depicted as a magenta isosurface. This density can be attributed to mobile VETF. c, Electrostatic potential mapped to the complete vRNAP solvent-accessible surface. The orientation of both views is identical to those depicted in b. The lowpass-filtered density overlay shown in b is not presented here.
