Changes in the diferric sMMOH diiron cluster occur upon MMOB binding and reduction. The ligands and iron atoms are identified as per the labels in panel A. (A) Alignment of the oxidized diiron clusters of unbound sMMOH with the sMMOHox:MMOB complex based on just the first-sphere ligands and iron atoms. Cyan – sMMOH alone (1MHY); Green – diferric sMMOH:MMOB complex (6YD0). (B) Ligand to Fe distances for isolated diferric sMMOH (1MHY). (C) Ligand to Fe distances for diferric sMMOH:MMOB (6YD0). (D) Ligand to Fe distances for anaerobic diferrous sMMOH:MMOB (6YDI). The Fe-Fe distance is labeled in orange text.
