TABLE 1.

MUSCLE multiple alignment percent identity scores of full-length amino acid sequences of ΦM9 T4-like phage universal core proteins and nearly universal core proteins with other T4 superfamily phages^a

^aOnly core proteins found in S. meliloti phage ΦM9 or ΦM12 were included in this analysis. See Table S3 in the supplemental material for sequences and accession numbers.

^b Sequences for which two ORFs separated by an intron have been unified.
