Figure 4. The two conserved structural mini-modules in the φPLPE group phages, excluding Aaφ23.
Color-coding is as in Fig. 2 and gene numbers refer to the φPLPE genome. ORF60 (“60″) is of unknown function, but could be implicated in the baseplate (BP). The two small ORFs upstream of the terL genes in φ1422 and ZF40 could be the terS genes. The terS/L genes in PY100 are not arranged as in the other phages and are far upstream and not side-by-side. All of the cellular hits shown are (conserved) hypothetical bacterial proteins, except for φ1422 which has a σ54 transcription regulator (“σ”).
