[[Flavodoxin]] (FDX) is a bacterial protein which contains flavin mononucleotide (FMN) or flavin adenine dinucleotide (FAD).  It participates in nitrogen metabolism and reduces N2 to NH3 while changing from its oxidized quinone state FDX-ox via semiquinone FDX-sq to its reduced hydroquinone state FDX-red<ref>PMID:8747466</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.
