The amino acid sequences of DNA polymerase subunit B of phage S0112 was aligned with those of the closely related bacteriophages, deposited in the NCBI database, using MUSCLE implanted in the MEGA 7.0 [36]. The maximum likelihood phylogenetic tree with 1000 bootstrap replications for DNA polymerase subunit B amino acid sequences was constructed by the model of Poisson. To find the closest relatives of phage S0112, the ViPTree was used to construct the viral proteomic tree [37].
