Fig. 1.

A view of the FeMo cofactor highlighting Fe atoms 2, 3, 6, and 7 (numbering from Protein Data Bank ID code 1M1N), along with MoFe protein amino acids ligands (α-275Cys and α-442His) and the side chains of α-195His and α-70Val. The figure was generated by using the Protein Data Bank ID code 1M1N. Fe is green, S is yellow, Mo is purple, C is gray, O is red, and N is blue.
