Genome of bacteriophage SfMu.

<p>The genome of phage SfMu is shown with a scale in bp. Predicted <i>orfs</i> are designated with arrows, pointing in the direction of transcription. Putative functional modules are indicated above the arrows. Black knobs indicate the position of predicted terminators. Comparison of SfMu encoded proteins to their counterparts in phage Mu and D108 is shown below the scale. Different colours show the level of amino acid identity: red: 90–100% identity, yellow: 80–89% identity, orange: 70–79% identity, green: 60–69% identity, blue: 50–59% identity and grey: 10–50% identity. The purple arrows in the SfMu map represent SfMu proteins which have no homologues in phage Mu or D108.
