Superposition of the SSX (violet), the cryo NvFdhAB (black; PDB entry 6sdr) and cryo formate-reduced NvFdhAB (green; PDB entry 6sdv) active sites, aligned based on MGD1. The W site with the two MGD cofactors, the sulfido ligand and Sec192 is shown as sticks; the W ion, sulfido group and Sec192 Se atom are shown as spheres (light blue, yellow and orange, respectively).
