FIG. 2.
Alignments of the int-guaA intergenic regions from S. aureus Mu50 (SaMu50), E. faecalis N00-410 (EfN410), and E. faecalis V583 (EfV583). The sequence from the equivalent region in C. perfringens CW459 is identical to that of S. aureus Mu50. Asterisks indicate an identical nucleotide in all three sequences, and periods indicate an identical nucleotide in two out of three sequences. The ΔG values of the inverted repeats are indicated after each sequence. DR, direct repeat; IR, inverted repeat.
