Fig 2. Chromosomal schematic of SlrV locus 1 and architecture of the slrV genes in 24 sequenced H. influenzae strains.

SlrV locus 1 is located between core genes encoding a putative transporting ATPase and peptide chain release factor 1 (prfA). Strain PittII contains four slrVA genes in tandem; two with 2 SLR and two with 4 SLR. These genes correspond to msfA1-4 in this manuscript. Only genes predicted to encode full-length products are illustrated. 7 genomes do not contain any full-length slrV gene at this locus. * denotes genomes in which SlrV locus 1 is located on the edges of contig breaks. Therefore it is possible that there are more slrV genes or SLR motifs located in the assembly gaps.
