FES 3001 A

Metal-MACiE entry for FES 3001 A

After the catalytic reaction the molybdenum center is reduced. The enzyme is then reoxidized by NAD+ or molecular oxygen in a reaction that occurs at the FAD (after electron transfer from the molybdenum center via the iron-sulfur centers) (PMID15148401). This FeS is near to molybdopterin.
