Table 4 Potential mobile regions and their major characteristics

From: The complete genome, comparative and functional analysis of Stenotrophomonas maltophiliareveals an organism heavily shielded by drug resistance determinants

Mobile region Putative length, approx. (bp) G+C content (%) Putatively bounded by (repeat length, bp) Major characteristics
Potential conjugative transposon 43,769 62.7 19 Hypotheticals, lipoproteins and an efflux protein cargo
Potential complex transposon insertion 97,538 61.9 18 Efflux transporters, mercury, arsenic and copper resistance, co-integrate resolution and integrases. May be a multiple insertion*
Potential complex transposon insertion 52,344 60.5 20 Tra genes and adhesins, DNA repair, conserved and unique hypotheticals. May be a multiple insertion. Carries IS elements and Tn5044 similarity
ISXac3-like 1,157 65.1 ND Seven intact copies and two pseudogenic copies
ISHne3/IS111A-like 915 61.7 ND Eleven intact copies
ISpsy9 1,352 58.8 ND Four intact copies
Phage cluster 1 118,000 63.7 ND Putative pseudogenic phage. Putative IS insertion and tRNA located centrally
Phage cluster 2 37,992 63.2 ND Putative intact phage
  1. Mobile regions were determined using an approach that combined using the Alien Hunter program, repeat analysis and by-eye comparisons between K279a and the X. campestris genome sequence by ACT analysis. *CDS (Smlt2465) in this feature shares 72.5% identity with a previously characterized transposase, Tn5044, from a Xanthomonas spp. isolated from a heavy metal mine in Russia [67]. Stenotrophomonas was at that time classified as Xanthomonas. ND, not detected.
