Figure 1

Crystal structure of P1. (A) Top and side views of the funnel-shaped P1 pentamer (the 5 subunits are in different colors). (B) The P1 subunit (rainbow-colored from blue at the N-terminus to red at the C-terminus) has a trapezoid shape with four edges labeled I - IV. The long helix-turn-helix (in gold) forms a “lever” that rotates during maturation of the procapsid. Five copies of the “tip” line the axial channel through the pentamer. The “corner” of one pentamer subunit fits against the “anchor” of a neighboring subunit. See also Figure S1.
