Extended Data Fig. 4: Functional roles of Pol ε amino acid side chains involved in proofreading and activity switching.

Pol ε cat in complex with PCNA, substrate DNA and incoming nucleotide is shown as ribbons. The positions of selected amino acids are indicated by red spheres, numbered 1–10. The table lists the residues at the respective sites and their roles in the activity of Pol ε and/or other representative polymerases.
