Genomic organization of Ngoφ1 – Ngoφ5 prophages in N. gonorrhoeae . Arrows oriented in the direction of transcription represent CDSs or genes. Arrows with black dots represents the replication module, solid arrows represent the structural module, and the arrows with vertical lines represent the CDSs encoding the repressors and other regulatory genes. The open arrows represent the CDSs with unknown function. Arrows with cross-hatching represent integrases. The filled rectangles (black or gray) represent putative non coding regions. The regions homologous for NgoΦ1, NgoΦ2 and NgoΦ3 are shown as rectangles with cross-hatched regions. The regions homologous for NgoΦ1 and NgoΦ2 are shown as solid black rectangles while those homologous for NgoΦ1 and NgoΦ3 as white open rectangles. The broken line representing the genome of NgoΦ3 (between CDSs 1640 and 1649) shows the site where the integrity of this genome is broken by the presence of part of the NgoΦ7 genome). The numbers at the beginning and end of each phage show the lengths of prophage genomes (in bp) while the numbers in parenthesis show the positions of prophages in N. gonorrhoeae FA1090 chromosome.
