FIG. 1.

Alignments of the sequences of (A) LamC and LamK and (B) LamA and LamR. Alignment was performed using ClustalW (http://searchlauncher.bcm.tmc.edu/multi-align/multi-align.html) and BOXSHADE (http://www.ch.embnet.org/software/BOX_form.html). Highly conserved residues are indicated by a black (identical) or gray (similar physicochemical characteristics) background. Bold lines with residue numbers indicate regions that define AIP specificity for the staphylococcal AgrC protein (A) or the HTH-LytTR DNA-binding domain of AgrA-like proteins (B).
