Phylogenetic analysis of the phage phiIPLA88 virion-associated peptidoglycan hydrolase HydH5 compared to several phage peptidoglycan hydrolases. The phylogenetic tree was constructed using the Neighbor-Joining method with 1000 bootstrap replicates and drawn to scale. The evolutionary distances were computed using the Poisson correction method and are expressed in the units of the number of amino acid substitutions per site. All positions containing gaps and missing data were eliminated from the dataset. Phylogenetic analyses were conducted in MEGA4 .
