Fig. 4: Structure of the AR9 nvRNAP core.
From: Structural basis of template strand deoxyuridine promoter recognition by a viral RNA polymerase
a Molecular surface of the AR9 nvRNAP core crystal structure (AR9 nvRNAP-core-Xray), with subunits colored as in Fig. 2a, with the downstream DNA oligonucleotide copied from the holoenzyme-promoter (AR9 nvRNAP-Pro-Xray) structure. The trigger loop insertion domain (TLID) partially obstructs the DNA binding cleft. b Electrostatic potential is mapped onto the molecular surface of the AR9 nvRNAP core. Both orientations are as in panel a.
