The heterologous siderophores ferrioxamine B and ferrichrome activate signaling pathways in Pseudomonas aeruginosa.
-
The ECF sigma factors FoxI and FiuI drive ferrioxamine B- and ferrichrome-specific induction of the receptors FoxA and FiuA.
"The involvement of this putative regulatory locus in the specific induction of the ferrioxamine B and ferrichrome receptors has been demonstrated"
Self-cleavage of the Pseudomonas aeruginosa Cell-surface Signaling Anti-sigma Factor FoxR Occurs through an N-O Acyl Rearrangement.
-
FoxI is the ECF sigma factor that transcribes foxA and is released from the anti-sigma factor FoxR on ferrioxamine signalling.
"Upon binding of ferrioxamine by the FoxA receptor, FoxR is processed by a complex proteolytic cascade leading to the release and activation of σ(FoxI)"
Transcription regulation of iron carrier transport genes by ECF sigma factors through signaling from the cell surface into the cytoplasm.
The role of FoxA, FiuA, and FpvB in iron acquisition via hydroxamate-type siderophores in Pseudomonas aeruginosa.
-
FoxA and FiuA import ferric hydroxamate siderophores.
"Iron complexed by desferioxamine G is transported by FpvB and FoxA, ferricrocin-Fe and ferrichrycin-Fe by FpvB and FiuA"
