additional information | F420 and the F420 redox moiety, FO, are phenolic 5-deazaflavin cofactors that complement nicotinamide and flavin redox coenzymes in biochemical oxidoreductases and photocatalytic systems. Specifically, these 5-deazaflavins lack the single electron reactivity with O2 of riboflavin-derived coenzymes (FMN and FAD), and, in general, have a more negative redox potential than NAD(P)+. A convenient synthesis of FO is achieved by improving the redox stability of synthetic intermediates containing a polar, electron-rich aminophenol fragment, Fno enzyme activity is restored with FO in the absence of F420, method optimization, overview | Archaea | ? | - |

physiological function | F420-dependent NADP+ oxidoreductase (Fno) is critical to the conversion of CO2 to CH4 by methanogenic archaea, while the F420 redox moiety, FO, functions as a light-harvesting agent in DNA repair | Archaea |
