title: Mutations affecting the citrate-dependent iron uptake system in Escherichia coli.
abstract: Isolation of six strains of Escherichia coli K-12 carrying mutations affecting the citrate-dependent iron uptake system is described. Genetic analysis of these mutants showed that the mutation affecting the citrate system are cluster together at about min 6 on the E. coli chromosome.
