Reaction: nitrilotriacetate + FMNH2 + H+ + O2 = iminodiacetate + glyoxylate + FMN + H2O
Systematic name: nitrilotriacetate,FMNH2:oxygen oxidoreductase (glyoxylate-forming)
Comments: Requires Mg2+. The enzyme from Aminobacter aminovorans (previously Chelatobacter heintzii) is part of a two component system that also includes EC 220.127.116.11 (FMN reductase), which provides reduced flavin mononucleotide for this enzyme.
