Figure 2. Comparative genomics of the eight φPLPE group phages.

Note that the previously published sequences of φPLPE and PY100 have been re-cut to a similar organization as Aaφ23. Gene abbreviations/functions are as follows: acylase, homoserine lactone acylase; ant, anti-repressor; atQ, anti-termination; bet, lambda recombination; BP, baseplate; cI/II, repressor; cro, anti-repressor; dnaC, replication; exo, exonuclease; H, head; hel, helicase; HNH, HNH (homing) endonuclease; hol, holin; int, integrase; lys, lysis; lyz, lysozyme; MCP, major capsid protein; meth, methylase; ninB/C/G, lambda recombination; nuc, nuclease; P, portal; pnk, polynucleotide kinase; pol, DNA polymerase; prim, primase; rec(T), recombination; recE, exonuclease VIII; rep(O/P), (λ) replication; Rz/Rz1, lysis; ssb, single-stranded binding; σ⁵⁴, bacterial transcriptional regulator; T, tail; terS/L, terminase; Tu, elongation factor; tetR, bacterial transcriptional regulator; trans, transposase; V, virion; xis, excisionase.
