Genetic map of bacteriophage SfV. (A) Relative locations of the different ORFs. Filled rectangle, cos site; filled circles, putative Rho-independent terminators as predicted by the GCG Terminator Program (refer to Table 2 for the sequence). Functional modules are indicated above the genetic map and are based on sequence and experimental analyses. (B) Regions of significant contiguous similarity (>77% identity at the nucleotide level) to other sequences in the data banks.
