Genome maps of KS5, KS14 and KL3. Genes transcribed from the plus strand are shown above and genes transcribed from the minus strand are shown below. The scale (in kbp) is shown on the bottom. The prophage gene order is shown for KS5 and KL3. The gene order for KS14 (which is maintained as a plasmid prophage) was chosen based on alignment with the other two sequences. Legend: orange, recombinase; yellow, transcriptional or translational regulation; black, insertion sequence; purple, tail morphogenesis; red, DNA modification; light blue, lysis; dark blue, capsid morphogenesis and DNA packaging; green, reverse transcription; brown, replication and partitioning; gray, unknown function.
