^amer includes merRTPAD and merE; ^b% identity with Tn5051 was not calculated for this region, as only 339 bp sequence data is available for Tn5051. Accession numbers: Tn501 from Pseudomonas aeruginosa plasmid pVS1 (Z00027), Tn21 from Shigella flexneri plasmid R100 (pNR1) (NC_002134), Tn4378 from Ralstonia metallidurans CH34 plasmid pMOL28 (NC_006525) and Tn5051 from Pseudomonas putida (Y17719).
