Genome maps of Φ16, Φ17A and Φ31 and comparison between the genomes and related phages Paz and Prado using a BLASTn analysis. The selected phages follow a modular genome organization, typical for lytic phages of the Autographiviridae: first an early transcribed region with a lot of ORFan genes, followed by the DNA metabolism region, the structural protein region and the lysis cassette. Arrows represent the different coding sequences: in white—encoding hypothetical proteins, blue—encoding DNA-associated proteins, green—encoding structural proteins and red—encoding the lysis cassette (adapted from EasyFig).
