The heterologous siderophores ferrioxamine B and ferrichrome activate signaling pathways in Pseudomonas aeruginosa.
-
The sigma factor and transmembrane sensor locus controls specific induction of the ferrioxamine and ferrichrome receptors.
"The involvement of this putative regulatory locus in the specific induction of the ferrioxamine B and ferrichrome receptors has been demonstrated"
Transcription regulation of iron carrier transport genes by ECF sigma factors through signaling from the cell surface into the cytoplasm.
-
FoxR and FiuR inhibit FoxI and FiuI; their cytoplasmic fragments have pro-sigma activity.
"The regulatory proteins FoxR and FiuR act as anti-sigma factors in that they inhibit the sigma factors FoxI and FiuI"
The role of FoxA, FiuA, and FpvB in iron acquisition via hydroxamate-type siderophores in Pseudomonas aeruginosa.
Self-cleavage of the Pseudomonas aeruginosa Cell-surface Signaling Anti-sigma Factor FoxR Occurs through an N-O Acyl Rearrangement.
-
FoxR is a transmembrane anti-sigma factor that inhibits FoxI.
"In the absence of ferrioxamine, the activity of σ(FoxI) is inhibited by the transmembrane anti-sigma factor FoxR."
