Ferric reductase A is essential for effective iron acquisition in Paracoccus denitrificans.
Original language description
Based on N-terminal sequences obtained from the purified cytoplasmic ferric reductases FerA and FerB, their corresponding genes were identified in the published genome sequence of Paracoccus denitrificans Pd1222. The ferA and ferB genes were cloned and individually inactivated by insertion of a kanamycin resistance marker, and then returned to P. denitrificans for exchange with their wild-type copies. The resulting ferA and ferB mutant strains showed normal growth in brain heart infusion broth. Unlike the ferB mutant, the strain lacking FerA did not grow on succinate minimal medium with ferric 2,3-dihydroxybenzoate as the iron source, and grew only poorly in the presence of ferric sulfate, chloride, citrate, NTA, EDTA and EGTA. Moreover, the ferA mutant strain was unable to produce catechols, which are normally detectable in supernatants from iron-limited wild-type cultures.
