FIG. 6.

Ami CWA domains from the 12 serovars of L. monocytogenes. (A) General organization of the Ami CWA domains in the various serovars. (B) Sequence alignments. We defined a consensus sequence (threshold, 96%) from the repeat region of each group. Dots indicate residues that are completely conserved in all repeats; positions are shaded if the chemical nature of the residues was conserved in all the sequences within the repeats, as follows: h, aliphatic residues (ILV); φ, aromatic residues (YFWH) (of the hydrophobic residues); +, basic residues (KHR); and -, acidic residues (ED) (of the polar residues). Secondary structure predictions are shown below the sequences; β-strands are represented by arrows.
