FIG. 3.

Genetic organization of the 6,388-bp region of φP27 DNA analyzed in this study (A) and comparison with a corresponding region of 9,760 bp of phage 933W (B). The arrows indicate the length and direction of transcription of ORFs. Black arrows indicate homologues DNA sequences of φP27 and 933W. Gray-shaded arrows represent ORFs with homologies to EMBL-GenBank sequences. ORFs labeled with white arrows had no significant homologies to sequences present in database libraries. The ORF labels of the 933W sequence were the same as those used by Plunkett et al. (22). tRNAs are depicted as black rectangles. The DNA regions marked with a lightly shaded rectangle represent 93% sequence identity. The scale is in kilobases.
