Figure 5. Global interactions of the L-stretch.

The L-stretch has extensive contacts with segments located in domain D1. (a) Overview of FlgE molecules that interact with the L-stretch motif through segments of their D1 domain. (b) A blown-up stereo view showing part of domain D1 (in yellow) of the FlgE (in position –5) that enlaces the L-stretch. (c) A blown-up stereo view showing segments of D1 domains of molecules at position –10 (blue) and –16 (grey), which interact with the tip of the L-stretch, and at position –11 (magenta) that interacts with the middle part of the L-stretch. The circled numbers indicate the order of appearance of each FlgE molecule during the building of the hook. Figure prepared with PyMOL.
