Nitrosomonas europaea has a single three-gene operon (nitABC) encoding an iron ABC
transporter system (NitABC). Phylogenetic analysis clustered the subunit NitB with Fe 3+ …

The chemolithoautotroph Nitrosomonas europaea has two genes predicted to encode outer-
membrane (OM) ferrioxamine transporters. Expression of the ferrioxamine uptake system …

Nitrosomonas europaea, as an ammonia-oxidizing bacterium, has a high Fe requirement
and has 90 genes dedicated to Fe acquisition. Under Fe-limiting conditions (0.2 μM Fe), N …

Anabaena sp. strain 6411, which produces the dihydroxamate siderophore schizokinen to
facilitate iron uptake, is also capable of using the related siderophore aerobactin. The two …

Analysis of a clinical isolate of Acinetobacter baumannii showed that this bacterium was
able to grow under iron-limiting conditions, using chemically defined growth media …

In Pseudomonas sp. strain M114, the outer membrane receptor for ferric pseudobactin M114
was shown to transport ferric pseudobactins B10 and A225, in addition to its own. The gene …

Uptake experiments with 59Fe3+ showed that Pseudomonas fluorescens had an active
system for iron transport. When the purified iron-binding pigment synthesized by this …

Iron is a key nutrient for almost all living organisms. Paradoxically, it is poorly soluble and
consequently poorly bioavailable. Bacteria have thus developed multiple strategies to …

The fbpABC operon in Neisseria gonorrhoeae encodes an ATP-binding cassette transporter
required for iron uptake from the host ferric binding proteins. The gene for the nucleotide …

A pyoverdine-deficient strain of Pseudomonas aeruginosa was unable to grow in an iron-
deficient minimal medium in the presence of the nonmetabolizable iron chelator ethylene …
