The 3D EM maps of PolD-PCNA-DNA complex. a Side view (upper) and top view (lower) of Form A. The crystal structures of PCNA and DP1 are shown in green and cyan ribbon models. The N-terminal, catalytic, center, and C-terminal domains of DP2 are shown in red, purple, yellow, and orange ribbon models, respectively. b Side view (upper) and top view (lower) of Form B. The ribbon models are colored as in a. The PCNA interacting with C-terminal loop of DP2, and harboring the PIP-box, are indicated by a red arrow in a and b
