The di-iron flavoprotein F420H2 oxidase found in methanogenic Archaea catalyzes the four-electron reduction of O2to 2H2O with 2 mol of reduced coenzyme F420(7,8-dimethyl-8-hydroxy-5-deazariboflavin). We report here on crystal structures of the homotetrameric F420H2 oxidase fromMethan-othermobacter marburgensis at resolutions of 2.25 A ˚ , 2.25 A ˚ and 1.7 A ˚ , respectively, from which an active reduced state, an inactive oxidized state and an active oxidized state could be extracted.
