Figure 36-5: Genetic organization of the replication region of P335 phages. Identified and putative functions are indicated at the top of the figure and genes are aligned according to this. Putative topoisomerases: top, single-stranded binding proteins: ssb, replication initiation proteins: rep, homologues to ORF17 of Tuc2009: orf17(2009), DnaC homologous proteins: dnaC, methylase: met, putative Holliday junction resolvases: rusA. Genes encoding similar proteins are shown as arrows with identical pattern. No similarity to other phage proteins: white, similar proteins with no identified function: black or gray. Small black boxes indicate location of origin of replication identified by experiments.
