Identification and characterization of novel pyoverdine synthesis genes in Pseudomonas aeruginosa.
Molecular basis of pyoverdine siderophore recycling in Pseudomonas aeruginosa.
-
PvdRT-OpmQ moves pyoverdine from the periplasm to the medium; mutants accumulate it in the periplasm.
"nearly all intracellular PVD was associated with the periplasmic fraction of pvdR , pvdT , and opmQ mutants"
-
PvdT is the inner-membrane ABC transporter component.
"Therefore, the entire PvdRT-OpmQ system (i.e., the IM ABC transporter PvdT, the periplasmic fusion protein PvdR, and the OM porin OpmQ) appears to be involved in the transport of PVD from the periplasm to the extracellular milieu."
An efflux pump is involved in secretion of newly synthesized siderophore by Pseudomonas aeruginosa.
-
PvdRT-OpmQ secretes newly synthesized pyoverdine.
"Bacteria lacking this efflux pump accumulated PVD, or a fluorescent precursor, in the periplasm, due to their inability to efficiently secrete into the media newly synthesized PVD"
The PvdRT-OpmQ efflux pump controls the metal selectivity of the iron uptake pathway mediated by the siderophore pyoverdine in Pseudomonas aeruginosa.
An efflux pump is required for siderophore recycling by Pseudomonas aeruginosa.
