Sequence alignment of Tn916, pCTN1046 and pLS51C. A linear comparison of the BLASTN matches between the extrachromosomal replicons pCTN1046 and pLS51C (harboured by L. salivarius strain SMXD51 [16]) and the conjugative transposon Tn916. Vertical grey-coloured blocks between sequences indicate regions of shared nt ID. The gradient of the grey colour corresponds to the percentage of shared nt ID (dark grey (100%)-light grey (75%)). The genes in each element are coloured according to their function in the conjugative transposon Tn916: pink (conjugative transfer), turquoise (accessory genes and transcriptional regulation), dark blue (transcriptional regulation) and yellow (recombination). Genes encoded by the plasmid backbone of pCTN1046 are green, and those associated with the backbone of pLS51C are dark purple.
