Figure 2

Schematic representation of pMEGA. Genes are depicted as arrows in the outermost circle; the arrowhead indicates the direction of transcription. Arrows coloured in red are involved in plasmid housekeeping functions (replication, partition, stability). Black arrows indicate genes involved in DNA rearrangements, orange arrows genes involved in metabolic functions, in navy blue defence genes, in green genes involved in mutagenesis, in purple in proteolysis and grey indicates genes with unknown function. The second outer circle depicts homology to Pseudoalteromonas arctica plasmid (>50% nucleotide identity); the third circle indicates homology to Pseudoalteromonas nigrifaciens plasmid (>50% nucleotide identity). The fourth and the fifth circle indicate homology to P. haloplanktis TAC125 chromosome I and II, respectively (>50% nucleotide identity). The intensity of the colour indicates the % of nucleotide identity, the more intense the colour is, the higher the % of identity is. The innermost circle represents the GC content.
