  • The Influence of Iron on Pseudomonas aeruginosa Physiology: A regulatory link between iron and quorum sensing 

    Oglesby, Amanda G.; Farrow, John M. III; Lee, Joon-Hee; Tomaras, Andrew P.; Greenberg, E. Peter; Pesci, Everett C.; Vasil, Michael L. (East Carolina University, 2008-06-06)
    In iron-replete environments, the Pseudomonas aeruginosa Fur (ferric uptake regulator) protein represses expression of two small regulatory RNAs encoded by prrF1 and prrF2. Here we describe the effects of iron and PrrF ...

  • Quinolone signaling in the cell-to-cell communication system of Pseudomonas aeruginosa 

    Pesci, Everett C.; Milbank, Jared B. J.; Pearson, James P.; McKnight, Susan L.; Kende, Andrew S.; Greenberg, E. Peter; Iglewski, Barbara H. (East Carolina University, 1999-09-28)
    Numerous species of bacteria use an elegant regulatory mechanism known as quorum sensing to control the expression of specific genes in a cell-density dependent manner. In Gram-negative bacteria, quorum sensing ...
