Figure 3
Structural comparison between ApePCNA1 and ApePCNA2. (a) Structure-based sequence alignment. Asterisks and colons indicate identical and highly similar residues, respectively. (b) Stereoview of the superposed structures. ApePCNA1 and ApePCNA2 are represented as C^α traces in sky blue and green, respectively.
