Figure 1. Crystal structure of the T4 prohead protease pentamer.

Figure 1

The polypeptide chains, shown as ribbons, are rainbow-colored from blue at the N-terminus to red at the C-terminus. Positions of the catalytic centers are shown by semitransparent spheres.

(A) View along the five-fold axis of the pentamer.

(B) View perpendicular to the five-fold axis.
