[[Flavodoxin]] (FDX) is a bacterial protein which contains flavin mononucleotide (FMN) or flavin adenine dinucleotide (FAD). It participates in nitrogen metabolism and reduces N<sub>2</sub> to NH<sub>3</sub> while changing from its oxidized quinone state FDX-ox via semiquinone FDX-sq to its reduced hydroquinone state FDX-red<ref>PMID:9416602</ref>. '''NrdI''' is a FDX which is involved in ribonucleotide reduction. '''WrbA (Tryptophan Repressor-Binding Protein)''' is also FDX. In ''E. coli'' there are 2 distinct flavodoxins: FDX I and II.
