TABLE 2.

MUSCLE multiple alignment percent identity scores of full-length amino acid sequences of ΦM9 “T4-like cyanophage core” proteins and “T4-like non-cyanophage 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. See Table 1 for the color code legend.

^b T4-GC, T4 gene cluster.

^c Proteins for which the ΦM12 homolog was detected in the proteome (10).
