Iron-requiring mutant of Escherichia coli carrying a deletion in the aroG-nadA region of the chromosome.
A mutant of Escherichia coli K-12 carrying a deletion in the aroG-nadA region of the genome requires a high concentration of iron for growth. The strain is chromium sensitive, and in the presence of citrate lower concentrations of iron support cell growth. The deletion mutant lost a gene between aroG and nadA that is responsible for the uptake of iron.
