Figure 6.
Map of the genome of P1312. The apparently circular genome is open arbitrarily at the upstream region of the head morphogenesis protein-encoding gene. Rightward arrowed boxes denote the ORFs encoded by the forward strand, while leftward arrowed boxes represent those encoded by the complementary strand. ORFs colored by red, blue, green, and magenta direct the synthesis of structural proteins, enzymes involved in DNA degradation/modification and cell wall modifications, enzymes participating in phage DNA replication, and transcriptional factors, respectively. The orange arrow denotes the presumed origin of DNA replication. Ticks on the scale are at intervals of 500 bp.
