    ..We show that the fis promoter is subject to stringent control and discuss this unusual feature with respect to the known and putative functions FIS serves in E. coli. ..

    ..coli that lack a functional fis gene demonstrates that Fis is not essential for cell growth under laboratory conditions but is required for high rates of Hin-mediated site-specific inversion in vivo. ..

    ..Thus, we propose that yhdG and fis were acquired by a lineage ancestral to the gamma proteobacteria in a single horizontal gene transfer event, and later diverged to their present functions. ..

    ..Fis is nonessential for Es. coli growth; however, inversion of the G segment of a Mu prophage was not detected in the fis mutant. The fis gene is located between 71 and 72 min on the Es. coli genetic map. ..

    ..Although no promoter activity was detected immediately upstream of prmA, S1 mapping detected 5' ends of mRNA in this region, implying that some mRNA processing occurs within the bicistronic panF-prmA mRNA. ..
