Phylogenetic trees of gut phages based on large subunit terminases. a Terminase_1; b Terminase_3; uncultured, black; Myoviridae, green; Siphoviridae, red; Podoviridae, blue. Unclassified cultured, yellow. Maximum-likelihood trees of all identified large subunit terminases from the identified large phage scaffolds and ENA phage genomes. The red branches in the trees denote the sequences from ENA phage genomes
