ATP + H2O + iron chelate/out = ADP + phosphate + iron chelate/in
ABC-type (ATP-binding cassette) ATPase, characterised by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports Fe-enterobactin, Fe-dicitrate, Fe-hydoxymate and other siderophores

ATP phosphohydrolase (iron-chelate-importing)
ABC-type (ATP-binding cassette-type) ATPase, characterized by the presence of two similar ATP-binding domains. Does not undergo phosphorylation during the transport process. A bacterial enzyme that imports Fe-enterobactin, Fe-dicitrate, Fe-hydroxamate and other siderophores.
ABC transporter system characterized, albomycin and salmycin sensitivity assays described, ferrichrome and ferrioxamine B transport assays applied, active transport of albomycin by the ABC transporter shown to mediate the high antibiotic efficacy of Streptococcus pneumoniae
ATP-transporter; components involved are FhuA (receptor), TonB, ExbB, ExbD and FhuC, FhuD, FhuB; FhuB protein composed of two identical halfes: FhuB(N) amino acid residues 1-333 and FhuB(C)amino acid residues 334-660, active when combined in a single polypeptide chain
insertion duplication mutants and deletion mutants generated in the fhuD, fhuB, and fhuG genes, complementation studies performed, mutants in the fhuD, fhuB and fhuG genes shown to be transport inactive and resistant to the antibiotics albomycin and salmycin
ATP-dependent ferric hydroxamate transport system in Escherichia coli: periplasmic FhuD interacts with a periplasmic and with a transmembrane/cytoplasmic region of the integral membrane protein FhuB, as revealed by competitive peptide mapping
