Esp_Z genome. a Circular representation of the Esp_Z genome. The coding regions of both the forward and reverse strands are shown in green; blue represents a negative deviation and red a positive deviation of the average G–C content for this genome of 55.8 %. b Evolutionary relationships between Esp_Z and related type and non-type strains, based on 16S rRNA genomic sequences and inferred by the UPGMA method. The optimal tree with the sum of branch lengths equal to 0.33591652 is shown. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the maximum composite likelihood method and are expressed as the number of base substitutions per site. The analysis was conducted in MEGA6 and involved 37 genomic sequences. c Distribution of the functional role categories of the protein-encoding genes of Esp_Z using the SEED database; 47 % of those genes were not assigned a functional role and are omitted from this representation
