Fig. 4. Conserved regions visualized in yeast RNAP protein structure.
Image of RNAP β (RPB2 subunit in eukaryotes) and RNAP β′ (RPB1 subunit in eukaryotes) subunit structures of S. cerevisiae (PDBid: 2e2i)24. Colors correspond to subunit and conserved regions. a Regions conserved across all examined taxonomic groups (Supplementary Dataset 3) when amino acid sequences of β and β′ are aligned separately. b Regions conserved between β and β′ across all examined taxonomic groups when β and β′ are aligned to each other (Supplementary Dataset 3).
