Schematic representation of Tn4401a inserted into pOX38-Gen (insertion I1 in Fig. 3). Genes and their corresponding transcription orientations are indicated by horizontal arrows. Tn4401a (isoform a [100-bp deletion as described in reference 13]) is delimited by two inverted repeat sequences, IRR and IRL (grey triangles). Small open triangles represent the inverted repeats of ISKpn6 and ISKpn7. Small arrows below the sequence represent primers used for direct sequencing of the insertion sites of Tn4401. The thick line corresponds to the pOX38-GEN DNA sequence.
