Prophage genome map of the C. diphtheriae prophage encoding DT Prophage genome map of the C. diphtheriae prophage encoding DT. The map indicates the modular structure of the corynephage by a color code and the annotated brackets. Prophage genome map of the C. diphtheriae prophage encoding DT. The map indicates the modular structure of the corynephage by a color code and the annotated brackets. The BFK20 bracket marks a region of high similarity to a Brevibacterium phage. Selected genes are annotated. Harald Brüssow et al. Microbiol. Mol. Biol. Rev. 2004; doi:10.1128/MMBR.68.3.560-602.2004
