Sequence alignments of AgrB. AgrB sequences from selected Gram-positive species were aligned using ClustalW308. Conserved residues are marked with gray boxes, and the essential histidine and cysteine residues are colored red. The colored lines above the sequence represent transmembrane regions as reported by Zhang et al.69 (red) or predicted using TOPCONs309 (green and black bars represent the two most common predictions). The 34 N-terminal residues conserved among S. aureus agr types are boxed.
