Fig 3. The pP36-Ph mobilizable genetic element.

Nucleotide and structural comparison of the chromosomally integrated element within L. pneumophila strains Philadelphia and Paris, and the potential episomal form are shown. Gene prediction for pP36-Ph is based on the current strain Paris annotations found at NCBI. The inner blue circle of the episome represents G+C content. Horizontal, solid grey strips represent identical, conserved sequence, while thin vertical black lines or solid black regions represent nucleotide differences (SNPs) between genomes. Thin horizontal black lines between solid grey regions represent gaps or deletions in the sequence. The nucleotide boundaries where pP36-Ph is integrated in the chromosome are shown above the sequence (relative to strain Philadelphia-1 and Paris), along with neighboring genes. A double jagged line represents additional internal sequence not shown.
