Pseudomonas aeruginosa secretes the fluorescent siderophore, pyoverdine (PVD), to enable iron acquisition. Epifluorescence microscopy and cellular fractionation were used to investigate the role of an efflux pump, PvdRT‐OpmQ, in PVD secretion. 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. PvdRT‐OpmQ is only the second system identified for secretion of newly… Expand
The PvdRT-OpmQ efflux pump controls the metal selectivity of the iron uptake pathway mediated by the siderophore pyoverdine in Pseudomonas aeruginosa.
TLDR
FpvA has a broad metal specificity for both the binding and uptake of PVD-metal complexes, and the PvdRT-OpmQ efflux pump exports unwanted metals complexed with PVD from the bacterium. Expand
High cellular organization of pyoverdine biosynthesis in Pseudomonas aeruginosa: clustering of PvdA at the old cell pole.
TLDR
The description of the intracellular distribution of these enzymes contributes to the understanding of the PVDI biosynthetic pathway. Expand
Biosynthesis of the pyoverdine siderophore of Pseudomonas aeruginosa involves precursors with a myristic or a myristoleic acid chain
TLDR
The use of mass spectrometry is described to determine the structure of two non‐fluorescent PVDI precursors and show that they both contain a unformed chromophore like ferribactin, and either a myristic or myristoleic chain that must be removed before PVDi is secreted into the extracellular medium. Expand
Pyoverdine biosynthesis and secretion in Pseudomonas aeruginosa: implications for metal homeostasis.
TLDR
The cellular localization of pyoverdine precursors was recently shown to be consistent with their biosynthetic enzymes, and a recently identified ATP-dependent efflux pump, PvdRT-OpmQ, is considered, which contributes to the understanding of the role of py overdine in iron and metal homeostasis in fluorescent Pseudomonads. Expand
Deciphering Protein Dynamics of the Siderophore Pyoverdine Pathway in Pseudomonas aeruginosa
TLDR
It is shown that most of the proteins involved in the PVD pathway are homogeneously distributed throughout the bacterial cell, and the first diffusion coefficients ever determined in P. aeruginosa are determined. Expand
Cellular organization of siderophore biosynthesis in Pseudomonas aeruginosa: Evidence for siderosomes.
TLDR
Recent findings indicate that the cytoplasmic enzymes involved in each of these two siderophore biosynthesis pathways can form siderphore-specific multi-enzymatic complexes called siderosomes associated with the inner leaflet of the cy Topolasmic membrane. Expand
Iron acquisition in Pseudomonas aeruginosa by the siderophore pyoverdine: an intricate interacting network including periplasmic and membrane proteins
TLDR
A multi-protein complex that drives iron release from PVDI in the periplasm of P. aeruginosa is highlighted, suggesting a role for FpvF in apo-PVDI recycling and secretion after iron delivery. Expand
Involvement of type VI secretion system in secretion of iron chelator pyoverdine in Pseudomonas taiwanensis
TLDR
It is shown that mutations in genes that encode components of the type VI secretion system (T6SS) as well as biosynthesis and maturation of pyoverdine resulted in reduced toxicity against Xoo, and indicated that T6SS is involved in the secretion of endogenous py overdine. Expand
PvdRT‐OpmQ and MdtABC‐OpmB efflux systems are involved in pyoverdine secretion in Pseudomonas putida KT2440
TLDR
The results provide first evidence for an involvement of the multidrug efflux system MdtABC-OpmB in pyoverdine secretion in Pseudomonas putida KT2440 and suggest a contribution of both efflux systems to ampicillin resistance. Expand
Involvement of major facilitator superfamily proteins SfaA and SbnD in staphyloferrin secretion in Staphylococcus aureus
TLDR
Deletion of sfaA resulted in a drastic reduction of SA secreted into the supernatant with a corresponding accumulation of SA in the cytoplasm and a significant growth defect in cells devoid of SB synthesis, while sbnD mutants showed transiently lowered levels of secreted SB, suggesting the involvement of additional efflux mechanisms.

An efflux pump is required for siderophore recycling by Pseudomonas aeruginosa.
TLDR
Data show that PvdRT-OpmQ is involved in recycling of PVDI from the periplasm to the extracellular medium and recycling requires release of the metal ion from PVDi. Expand
Molecular basis of pyoverdine siderophore recycling in Pseudomonas aeruginosa
TLDR
A tripartite ATP-binding cassette efflux transporter, here named PvdRT-OpmQ, is identified, which translocates PVD from the periplasmic space to the extracellular milieu and is shown to be responsible for recycling of PVD upon internalization by the cognate outer-membrane receptor FpvA, thus making PVD virtually available for new cycles of iron uptake. Expand
Pyoverdine-Mediated Iron Uptake in Pseudomonas aeruginosa: the Tat System Is Required for PvdN but Not for FpvA Transport
TLDR
PdN, a still unknown but essential component in Pvd biogenesis, was located at the periplasmic side of the cytoplasmic membrane and showed that its export is Tat dependent. Expand
Synthesis of the siderophore pyoverdine in Pseudomonas aeruginosa involves a periplasmic maturation
TLDR
Using the fluorescent properties of PVDI, the pyoverdine produced by Pseudomonas aeruginosa PAO1, it was able to show that PVD i was not present in the cytoplasm of the bacteria, but large amounts of a fluorescent PVDi precursor PVD Ip were stored in the periplasm. Expand
Pyoverdine siderophores: from biogenesis to biosignificance.
TLDR
Pyoverdines are a group of structurally related siderophores produced by fluorescent Pseudomonas species and the extremely high sequence diversity of genes involved in pyoverdine synthesis and uptake indicate that py overdine production is subject to high evolutionary pressure. Expand
Export of the siderophore enterobactin in Escherichia coli: involvement of a 43 kDa membrane exporter
TLDR
Data establish that P43 is a critical component of the E. coli enterobactin secretion machinery and provides a rationale for the designation of the previous genetic locus ybdA as entS to reflect its relevant biological function. Expand
Role of TonB1 in Pyoverdine-Mediated Signaling in Pseudomonas aeruginosa
TLDR
It is shown that interactions between FpvA and TonB1 are required for (ferri)py overdine signal transduction, as well as for ferripyoverdine transport, consistent with a mechanistic link between the signaling and transport functions of F pvA. Expand

TLDR
This review focuses on the mechanisms underlying iron uptake by the Pvd pathway in pseudomonads, taking into account recent biochemical and biophysical studies and recently solved 3D-structures of the PvD outer membrane transporter FpvA in four different loading states. Expand
FpvB, an alternative type I ferripyoverdine receptor of Pseudomonas aeruginosa.
TLDR
In silico analysis of the PAO1 genome revealed that the product of gene PA4168 has a high similarity with FpvA, and introduction of fpvB in trans restored the capacity to utilize type I ferripyoverdine. Expand
