The cytoplasmic heme-binding protein PhuS, encoded within the Fur-regulated Pseudomonas heme utilization (phu) operon, has previously been shown to traffic heme to the iron-regulated heme oxygenase (HO). We further investigate the role of PhuS in heme trafficking to HO on disruption of the phuS and hemO genes in a Pseudomonas aeruginosa(More)
Cytoplasmic male sterility (CMS) represents an important agricultural trait in pearl millet [Pennisetum glaucum (L.) R. Br.] with a value to the seed industry in facilitating economical hybrid seed production. Among the CMS systems available in millet, the A1 source is the most commonly used for hybrid production, but it can undergo low frequency reversion(More)
Enteroaggregative Escherichia coli (EAEC) causes diarrhea in diverse populations worldwide. The AraC-like regulator AggR is a key virulence regulator in EAEC. AggR-regulated genes include those encoding the Aggregative Adherence Fimbria, the dispersin protein, and a type VI secretion system. This study characterizes the regulation of the aggR promoter(More)
In order to better characterize the Bacillus anthracis typing phage AP50c, we designed a genetic screen to identify its bacterial receptor. Insertions of the transposon mariner or targeted deletions of the structural gene for the S-layer protein Sap and the sporulation genes spo0A, spo0B, and spo0F in B. anthracis Sterne resulted in phage resistance with(More)
Heme uptake and utilization by pathogenic bacteria are critical for virulence and disease, since heme and heme proteins are a major source of iron within the host. Although the role of outer membrane heme receptors in this process has been extensively characterized at the genetic and biochemical level, the role of the cytoplasmic heme binding proteins is(More)
