New functions of pirin proteins and a 2-ketoglutarate: Ferredoxin oxidoreductase ortholog in Bacteroides fragilis metabolism and their impact on antimicrobial susceptibility to metronidazole and amixicile. New functions of pirin proteins and a 2-ketoglutarate: Ferredoxin oxidoreductase ortholog in Bacteroides fragilis metabolism and their impact on antimicrobial susceptibility to metronidazole and amixicile

Genome expression study of Bacteroides fragilis strain 638R comparing a fur deletion mutant with the wild-type strain grown in minimal defined media with iron-replete or iron-limiting conditions following oxygen exposure. The construction of the fur mutant analyzed in this study was described in Robertson KP, Smith CJ, Gough AM, Rocha ER. Characterization of Bacteroides fragilis hemolysins and regulation and synergistic interactions of HlyA and HlyB. Infect Immun. 2006 74:2304-2316. Overall design: 10 chip study with 8 technical replicate on each chip comparing iron and oxygen regulated genes in the wild-type strain and fur deletion mutant.
