Fig. 4.
Docking of atomic models into the PomAB map shown in Fig. 3A to C. (A) Structure viewed from the same direction as in Fig. 3A. (B) Structure rotated by 90°, as in Fig. 3B. (C) Structure viewed as in Fig. 3C. Two atomic models of the core of the MotBC PG-binding domain from H. pylori (PDB accession code 3CYP) (48) are shown in red and blue. They were docked into the arm domains. Arrows in panels A and B indicate the stalk and shoulder of the arm (see text), and the horizontal bars in panel A refer to the TM region. The scale bar in panel C represents 25 Å.
