GR13 plasmid pDETAB5. (a) Circular map of pDETAB5 drawn from GenBank accession CP072528. Plasmid sequence is shown as a black line, with arrows inside representing ORFs. Coloured boxes represent IS. Black lines marked ‘C/D’ or ‘D/C’ represent pdif sites and indicate their orientations. Arrows filled with blue and labelled rep, parAB and tyr13 represent the GR13 genes of pDETAB5. (b) Linear maps of pDETAB2, pDETAB5 and pDETAB13, drawn to scale from GenBank accessions CP047975, CP072528 and CP073061. Near-identical sequences in pDETAB2 and pDETAB5 are bridged by grey shading and homologous regions of pDETAB5 and pDETAB13 are marked by lines labelled ‘a’ to ‘h’. IS are shown as coloured, labelled boxes and the locations of ARGs are indicated.
