Protein sequence alignments for the BcfD (A) and StfH (B) allelic groups from S. Newport. Protein sequence alignments for the BcfD (A) and StfH (B) allelic groups from S. Newport. Alignments were made using ClustalW (MegAlign; DNAStar, Madison, WI). Identical amino acids are shadowed in black with white text, while different amino acids appear as black text with no shadowing. Allelic sequence labels are indicated at left and amino acid positions at right. Arrows indicate predicted signal sequence cleavage sites.
