Comparison of HmuY homologues. Comparison of homologous HmuY amino-acid sequences identified in human pathogens (A) and bacteria identified in oral tissues (B). Amino-acid sequences lacking signal peptides are shown. Positions with identical amino acids in more than 30% of the sequences are shown in black boxes and partial homology is indicated in grey boxes. Phylogenetic relationship between homologous HmuY amino-acid sequences (C). Bacteria infecting the oral cavity are shown in bold. The phylogenetic tree was determined with the Neighbor-Joining method. Bootstrap values are included.
