FIG 3.

Schematic representation of the genomes of lineage 3 (MM25 and 9A) and lineage 4 (M19) phages and their comparison to the first isolate of the study (STP1, lineage 1). Arrows (indicating protein-encoding regions) joined by shaded boxes indicate genetic regions of similarity, with the black shading indicating 90 to 100%, dark gray indicating 80 to 89%, light gray indicating 50 to 79%, and off-white indicating 30 to 49% aa identity. Arrows of the same color represent genes with a similar function. Gray arrows are indicative of genes encoding proteins of unknown function. The predicted functions of the encoded proteins are presented above the relevant arrows, where known and the functional modules are presented below the schematic. The lineage (L3/4) and source (F, factory; E, external) are also presented on the left side of the figure.
