Figure 3. Interactions that Build up the p21 Octameric Ring.

Figure 3

(A) The NTDs interface with key interacting residues shown in stick representation. The N-terminal tail plays a critical role in the association of neighboring NTDs. Also shown are the conserved interactions that stabilize the orientation between NTD and CTD within one monomer subunit. The NTD, CTD, and the neighboring NTD′ are colored magenta, blue, and cyan, respectively. The prime symbol in the labels denotes the other molecule.

(B) The hydrophobic interface between the blue-colored CTD and its neighboring cyan-colored CTD′.
