Palindromic Haemophilus DNA uptake sequences in presumed transcriptional terminators from H. influenzae and H. parainfluenzae.
We have found palindromic pairs of near matches to the 11-bp Haemophilus DNA uptake motif shortly after the stop codons of three Haemophilus genes. Short runs of thymidylate residues follow the stem-loop structures thus defined. This organization suggests that, in H. influenzae, the uptake motif may be preferentially incorporated into gene termination signals, as has been proposed for Neisseria gonorrhoeae.
