FIG. 6.
Alignment of putative DNA uptake sequences. The four arms of inverted repeats that contain the 11-bp consensus sequence (see Fig. 4) were aligned. Shown below are the 11-bp sequence that is repeated 848 times in the incomplete A. actinomycetemcomitans genome sequence and the 9-bp DNA uptake sequence (USS) that is repeated 1,465 times in the H. influenzae genome.
