FIG. 4.

(A) Predicted amino acid sequence of FliX. The possible signal peptide sequence is underlined, and the cleavage site is indicated by a vertical arrow. Numbers indicate amino acids. (B) Hydrophobicity plot of the FliX protein. The graph was generated by the Hydrophobicity Plot program in the DNA Strider package. Negative values indicate hydrophilic regions, and positive values indicate hydrophobic regions. (C) Alignment of C. crescentus (Cc) DksA with the homologs from E. coli (Ec) (25) and H. influenzae (Hi) (17). Asterisks indicate identical amino acids.
