Fig. 4. Surface representation. (A) Top view onto AAA ring. Phe-234 residues are colored in yellow and magenta, and Arg-318 is in orange. The orientation is the same as in Fig. 2A. ADP residues are shown as sticks. Subunits are shaded alternately light and dark. (B) Modeled ideal hexameric arrangement of the AAA domains. The protease ring is in the same orientation as in A and Fig. 2A.
