Extended Data Fig. 7: Rbp6 NTT occupies the active center cleft of Pol II.
From: Structures of transcription preinitiation complex engaged with the +1 nucleosome

a. Crosslinks between Rpb6 NTT and other Pol II subunits. The close-up view shows three observed EDC crosslinks (black dashed lines). b. Sequence alignment of Rpb6 orthologs. The NTT regions are boxed. Acidic residues of Rpb6 NTT that are involved in interaction with the Pol II cleft are indicated in bold.
