Heme Iron Nitrosyl Complex of MauG Reveals an Efficient Redox Equilibrium Between Hemes with Only One Heme Exclusively Binding Exogenous Ligands

MauG is a diheme enzyme that oxidizes two protein-bound tryptophan residues to generate a catalytic tryptophan tryptophylquinone cofactor within methylamine dehydrogenase. Upon the two-electron oxidation of bis-ferric MauG, the two c-type hemes exist as a spin-uncoupled bis-Fe(IV) species with only...
