FES 3908 x

Metal-MACiE entry for FES 3908 x

The enzyme uses two iron-sulfur Fe2S2 cluster which are involved in transferring electrons out of the buried molybdopterin cytosine dinucleotide to an FAD (PMID12475995). This Fe2S2 cluster is involved in tranferring electrons from the first Fe2S2 cluster (FES_3907) to the FAD cofactor (PMID12475995).
