FIGURE 5.
Summary of Salmonella FlhA and Y. pestis LcrD mutants. A, the locations of Salmonella FlhAC Δ6, Δ17, and Δ18 deletions are mapped onto the H. pylori FlhA structure, depicted in a ribbon diagram, and colored according to Fig. 2 (16). B, the positions of nonsense mutations that result in truncation of the C-terminal domain in Salmonella FlhA or Y. pestis LcrD, respectively, are mapped onto the H. pylori FlhAC structure and drawn in red and labeled according to the position in the parent sequence (34, 35, 48). The position of an internal Salmonella FlhA deletion (Δ600–644) that permits early secretion of filament class substrates is also shown in blue (48).
