Binding and transport through ferric siderophore receptors, FepA and FhuA.
(2006)Under iron deficient conditions, Gram-negative bacteria like E. coli secrete siderophores to chelate iron in the extracellular medium. Ligand-gated porins (LGPs) transport the ferric siderophore complexes across the outer ... -
Cell surface exposure and immunogenicity of foreign epitopes in outer membrane proteins.
(2001)To evaluate the accessibility of epitopes to the extracellular environment, bacteria expressing LamB:V3 or OmpA:TOP chimeric protein were fluorescently labeled with mouse anti-gp120 (V3), and analyzed by cytofluorimetry. ... -
Mechanism of ferric enterobactin transport through Escherichia coli FepA: The evolution of a bacterial venus flytrap.
(2001)The TonB-dependent, energy dependent ferric siderophore transporters of the gram-negative bacterial outer membrane possess a unique architecture: Their N-termini fold into a globular domain that lodges within, and physically ... -
TonB dependent transport processes through Escherichia coli FepA.
(2007)One of the previously proposed mechanisms of TonB is called the "shuttle hypothesis" which states that TonB shuttles from the inner membrane to the outer membrane. The data presented here demonstrates that TonB does not ...
