http://purl.uniprot.org/citations/10689178http://www.w3.org/2000/01/rdf-schema#comment"The exbBD genes of Pseudomonas aeruginosa PAO were cloned by complementation of the growth defect of an Escherichia coli exbB tolQ double mutant on iron-restricted medium. Nucleotide sequence analysis confirmed that these genes are contiguous and preceded by a second tonB gene in this organism, which we have designated tonB2. lacZ promoter fusions confirmed that expression of the tonB2-exbB-exbD genes is increased under conditions of iron limitation. Deletions within any of these genes, in contrast to deletions in the first tonB gene, tonB1, did not adversely affect growth on iron-restricted medium. On the other hand, tonB1 tonB2 double mutants were more compromised as regards growth in an iron-restricted medium than a tonB1 deletion, indicating that TonB2 could partially replace TonB1 in its role in iron acquisition. TonB1 but not TonB2 deletion strains were also compromised as regards the utilization of hemin or hemoglobin as sole iron sources, indicating that heme transport requires TonB1."xsd:string
