Alignment of potential ATPase domains of the large terminase subunit from herpesviruses and bacteriophages. Large terminase sequences of DEV(UniProtKB accession code C6ZD26), HSV-1 (P04295), HCMV (P16732), EBV (P03219), bacteriophage T4 (P17312), bacteriophage P7 (Q5XLR0) and bacteriophage HK97 (Q9MCT1) were aligned with the ClastalW2 multiple sequence alignment program[42]. The P7 terminase sequence was adjusted manually for the significant deviation in the distance between the motifs. The putative Walker A motifs of each sequence are underlined and in red and the Walker B motif are in blue. Numbers in brackets are the number of residues omitted.
