Hydroxamate recognition during iron transport from hydroxamate-ion chelates.
Kinetics of radioactive iron transport from three structurally different secondary hydroxamate-iron chelates (schizokinen-iron, produced by Bacillus megaterium ATCC 19213; Desferal-iron, produced by an actinomycete; and aerobactin-iron, produced by Aerobacter aerogenes 62-1) revealed that B. megaterium SK11 (a mutant which cannot synthesize schizokinen) has a specific transport system for utili...
متن کاملHydroxamate Siderophore from Bacillus sp SD12 Isolated from Iron Factory Soil
The present study reports siderophores production from bacteria isolated from Iron factory soil and its antifungal activity. Of the twelve morphologically different bacterial cultures isolated from iron factory soil, Kanchipuram, only two strains SD6 and SD12 showed siderophores production in Chrome Azurol S assay. Strain SD12 which showed maximum siderophores production, was selected for furth...
متن کاملIron-binding compounds from Agrobacterium spp.: biological control strain Agrobacterium rhizogenes K84 produces a hydroxamate siderophore.
Iron-binding compounds were produced in various amounts in response to iron starvation by a collection of Agrobacterium strains belonging to the species A. tumefaciens, A. rhizogenes, and A. vitis. The crown gall biocontrol agent A. rhizogenes strain K84 produced a hydroxamate iron chelator in large amounts. Production of this compound, and also of a previously described antibiotic-like substan...
متن کاملHigh-affinity iron uptake systems present in Erwinia carotovora subsp. carotovora include the hydroxamate siderophore aerobactin.
The phytopathogenic bacterium Erwinia carotovora subsp. carotovora W3C105 produced the hydroxamate siderophore aerobactin under iron-limiting conditions. A survey of 22 diverse strains of E. carotovora revealed that strain W3C105 alone produced aerobactin. The ferric-aerobactin receptor of strain W3C105 was an 80-kDa protein, identified by immunoblots of Sarkosyl-soluble proteins obtained from ...
متن کاملHydroxamate Production as a High Affinity Iron Acquisition Mechanism in Paracoccidioides Spp
Iron is a micronutrient required by almost all living organisms, including fungi. Although this metal is abundant, its bioavailability is low either in aerobic environments or within mammalian hosts. As a consequence, pathogenic microorganisms evolved high affinity iron acquisition mechanisms which include the production and uptake of siderophores. Here we investigated the utilization of these ...
