Fig. 5. SNAPc–general transcription factors interaction.

Fig. 5

a, Structure of SNAPc-containing Pol II PIC, with subunits of SNAPc colored as in Figure 3. b, Close-up view of the wing-1–TFIIA interaction. The amino acid residues involved in the formation of interfaces A and B between TFIIA and SNAPC4 are represented as sticks. Dashed lines indicate salt-bridges. c, Zoomed-in view of the interface C formed between wing-2 and TFIIB C-terminal cyclin fold. The Cα atoms of putative residues forming the interaction surface are represented as spheres.
