Rings in the Extreme: PCNA Interactions and Adaptations in the Archaea

Figure 5

Detailed comparison of the PIP-box interactions of AfuPCNA with a Fen1 peptide (1RXZ) and RNase H (3P83) [12, 15]. The left hand panel depicts the binding partners in cartoon representation and the right hand panel in stick form. The Fen1 complex is shown in light/dark blue and the RNase H complex in pink/purple. Key features and conserved residues in the PIP-box are indicated.
