… Thus, we report a ligand exchange step in siderophore-mediated microbial iron transport. …
We suggest that this siderophore shuttle transport mechanism may be widespread in bacteria. …

… on the coordination chemistry of the microbial iron chelators called siderophores. The initial
… The salient features of the siderophore shuttle mechanism are apo-siderophore binding by …

… The electron transfer ability of the iron atom is modified by the ligand environment in which …
Any discussion of whether plants can utilize microbial siderophores as iron sources must start …

… It is based on the color change that accompanies transfer of the ferric … siderophore. A
detergent must be present in order to achieve the intense color; otherwise, only a charge-transfer …

… (26) Two working models for siderophore-mediated iron transport were proposed by Raymond
and co-workers based on findings from these seminal studies (Figure 1). In the first model…

… release mechanism likely involves reduction of Fe 3+ with removal and transfer of Fe 2+ to
various acceptor molecules within the cytoplasm; less frequently occurring are mechanisms …

… siderophores and the reactivity that these characteristics confer. Relatively little is known
about marine microbial iron transport … Fbp serves to shuttle iron from the inside of the outer …

… as ferredoxins can catalyze the transfer at very low potential of the electrons necessary to
the energetic metabolism of anaerobic bacteria. On the contrary. iron porphyrins, such as in …

… (II), an intermediate in many biological iron transport processes. Hence, Ga-DFO can be
used as an irreducible FO analog. The binding ability of the YxeB proteins for Ga-DFO was …

… Much less is known about the iron transport of Gram-positive bacteria, even though many
are … siderophore-shuttle mechanism to transport Fe-siderophores when apo-siderophore is …
