Figure 2

Amino acid sequences from the receptor-binding domain (RBD) residues (128–144) of six pilin strains of Pseudomonas aeruginosa. Yellow shaded residues indicate positions of identity or conservative substitutions, grey shaded residues indicate sequence identity between five of the six strains. PAK-K and PAK–R pilin strains are identical in sequence except for the C-terminal residue K or R at position 144. The nine variable positions between the strains are shown in white. Residues in each of these positions vary dramatically in side-chain and type (charged, polar, and non-polar).
