Multiple-sequence alignments of the regions showing the characteristic homology boxes of the HK proteins. Because the corresponding HK proteins of the eight S. mutans strains in this study were highly similar, S. mutans UA159 was used as their representative, wherever possible. The different HK families were obtained as a result of the classification schemes described by Grebe [15].
