Scheme of the variable genomic region downstream the conserved gene trpP in P. damselae subsp. damselae genomes. The fimbrial gene cluster found in strain DK3 in this position, is also present in nine additional strains (Figure 1). A total of 12 strains, including DK20, contain a different gene repertoire that includes the genes of a hypothetical protein of 11 kDa and a putative protein secreted by the Twin-arginine (Tat) pathway, respectively. The genomes of DK2 and DK29 do not harbor genetic material inserted between the two conserved genes depicted in red. Interestingly, the putative transcriptional terminator region of trpP contains a series of 8-mer and 11-mer direct repeats (represented in different colors) that might play a role in foreign DNA acquisition. The stop codon of trpR is represented in high caps and bold. Note that the sequence downstream this stop codon differs between strains.
