Remark 600 | HETEROGEN The ligand WCC is a Ni-Fe-S cubane. There is an unidentified ligand, UNX, bound to the Ni ...HETEROGEN The ligand WCC is a Ni-Fe-S cubane. There is an unidentified ligand, UNX, bound to the Ni of the WCC. There is also a FE2 bound to the cubane. The C-cluster, as it is called, has a single iron site (FE2) and a four-metal cubane (Ni-Fe-S). |

There are 3 homodimers in the asymmetric unit: chains A&B, C&D, and E&F. Molecules C&D, E&F have lower B-factors than A&B, and are the molecules that should be considered in structural analyses. No side chain density was seen for residue 348.
