Abstract:
:Integration host factor (IHF) binds to two sites near the origin of transfer of the conjugative antibiotic resistance plasmid, R100. DNase I footprinting shows that one site is immediately adjacent to oriT and the gene X promoter, and another is adjacent to the traM promoter. A third site, known only from retardation gels, is near the traJ promoter. The relative promoter activities of genes X, traJ and traM are reduced in himA mutants (IHF-), as measured by chloramphenicol-resistance assays. Transcript analyses by Northern blots showed a reduction in size of the principal gene X and traJ transcripts in the absence of IHF.
