Crystal structure of the nitrogenase iron protein from ,tion, electrons are transferred from Fe-protein to MoFe-protein in an ATP-dependent process. The coupling of ATP hydrolysis to electron transfer is mediated by Fe-protein, which is the only known reductant of MoFe-protein supporting catalytic activity (8). Fe-protein is a dimer of two identical 32kD

Structure of the nitrogenase MoFe protein: Spatial distribution of the intrinsic metal atoms determiis of a series of EPR and Mössbauer experiments [1]. This model defined two types of metal-sulfur clusters, M-centers and P-clusters. The original and current versions of the model both identify the M-centers as FeMo-cofactors. Two are bound per α.β. tetramer; each comprises 1 Mo and 6–7 Fe atoms. P
