FIG. 3.

The region upstream from purE in H. influenzae. (a) Sequence of the R3001 insert and inferred amino acid sequences of hicA and hicB. AluI sites flanking the hic probe are shown (boxes). (b) Alignment of the purE-hifA region in various strains. Dots signify identity, letters indicate sequence differences, and dashes are gaps. Position 1 is the initiating A of the purE coding sequence, and the carboxy-terminal amino acids of HifA (E Y A) are indicated. C2859 has a 246-bp insertion immediately following the 57-bp repeat.
