Genome alignments of CP220 and CPt10. Nucleotide alignment of the virulent bacteriophages CP220 (top) and CPt10 (bottom) generated using the Artemis Comparison Tool (ACT). The CDS regions are indicated by bars top and bottom showing the 'forward' and 'reverse' strands. CDS regions are coloured according to the following key: grey - areas of nucleotide identity, white - significantly different CDS regions present in only one of the genomes, solid black - repeat regions (numbered according to the current genome annotation), red - DNA modification proteins, blue - insertion elements, pink - radical SAM proteins. Red bars indicate regions of sequence homology, the diagonal lines link multiple repeat regions in both genomes indicating the conserved nature of these sequences throughout both genomes.
