Phylogenetic relationships among 16S rRNA methyltransferases determined using CLUSTALW. The GenBank accession numbers of plasmid-borne 16S rRNA methyltransferase genes are as follows: ArmA, AY220558; RmtA, AB083212; RmtB, AB103506; RmtC, AB194779; RmtE, GU201947; RmtF, JQ808129. Kmr (accession no. Y15838) is a chromosomal 16S rRNA methyltransferase from aminoglycoside-producing Streptomyces kanamyceticus. The scale bar represents a 10% amino acid sequence difference. The values in parentheses are percentages of identity relative to RmtF.
