a, b Ribbon diagrams of the AR9 nvRNAP and RNAP-σE (PDB code 6JBQ22), respectively, are viewed from the NTP entrance channel. Nucleic acids are not shown for clarity. Gp226 and σE extend into the plane of the paper and are almost completely obscured by the depth-cueing effect. In both molecules, key elements are colored similarly and labeled. In panel a, the color code is as in Fig. 2a.
