Figures & data

Figure 1. Comparative analysis of tet(X4)-harboring plasmids and chromosome. (A) Structures of p14EC001c (CP024130), p3_W5-6 (CP032995) and the tet(X4)-harboring plasmid p2FT39-3. (B) Structures of pSE81-1705-1 (CP018652), pHCM1 (AL513383), the tet(X4)-harboring plasmid p2FT38-2-1 and tet(X4)-harboring chromosome region in E. coli 2ZN37-2. (C) Genetic environments of tet(X4). Results of nucleotide sequence alignment are generated with Easyfig [Citation15]. The arrows represent the positions and transcriptional directions of the ORFs. Regions of homology are marked by shading. The putative oriIS (left-facing sticks in purple) and terIS (right-facing sticks in purple) of the ISCR2 element are also illustrated (5′ to 3′). Δ symbol indicates that the gene is truncated.
