The class 1 integron In28, found in the multidrug resistance transposon Tn1403, was found to be located in the res site of the backbone transposon and is flanked by a 5-bp direct duplication, indicating that it reached this position by transposition. (nih.gov)
In1, the class 1 integron found in the multidrug resistance plasmid R46, is also located in a putative res site and belongs to the In4 group. (nih.gov)
additional Tn RErm46 copies generated by transposition from original insertion may be present) and class 1 integron (C1I, in yellow) with associated tetRA (33) tetracycline-resistance cassette (peach). (cdc.gov)
