a Cryo-EM map of the AR9 nvRNAP holoenzyme (AR9 nvRNAP-holo-cryoEM) contoured at 4.0 std dev above the mean (semitransparent gray) with the fitted as a rigid body atomic model of the AR9 nvRNAP promoter complex sans DNA (AR9 nvRNAP-Pro-Xray) and is colored as in Fig. 2a. b A zoomed-in view of the catalytic cleft demonstrating the degree of gp226 disorder.
