Fig. 5.

The structural organization and GC profiles of the clb determinants in the five most genetically distant bacterial strains (according to Fig. 2a). The genes that make up the homologous pks gene cluster found in F. perrara and the most distant clb determinants present in Serratia marcescens, Erwinia oleae, K. michiganensis and Escherichia coli (phylogroup E) strain 14696-7 are depicted. The GC profile of the gene cluster in the different strains is shown alongside with the colours underlining the different species. SAM genes and clbA homologues (*) are shown downstream of the pks gene cluster in F. perrara and upstream of the clb determinant in K. michiganensis and Erwinia oleae. The gaps in assembly are shown with white spaces.
