| Abstract: | A ferrous iron transport system in Escherichia coli is described. Mutants in this transport system were isolated using the antibiotic streptonigrin. The gene locus feo (for ferrous iron transport) was mapped near pncA at 38.5 min on the genetic map of E. coli K12. The transport of ferrous iron was regulated by fur as the siderophore transport systems. |
