Figure 36-3: Genetic organization of the lysogeny module of temperate P335 phages. Identified and putative functions are indicated at the top of the figure and genes are aligned according to this. Integrase: int, super immunity exclusion: sieA, part of Sie system and metallo proteinase motif protein: sieB, cro-like: cro, anti-repressor: ant, excisionase: xis. 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. Small black arrows indicate promoters identified by biological experiments, while location of identified repressor operator sites are shown as small black boxes.
