Crystallographic structure and functional implications of the nitrogenase molybdenum–iron protein from Azotobacter vinelandii

Nature volume 360, pages 553–560 (1992)Cite this article

Abstract

The crystal structure of the nitrogenase molybdenum–iron protein from Azotobacter vinelandii has been determined at 2.7 Å resolution. The α- and β-subunits in this α2 β2 tetramer have similar polypeptide folds. The FeMo-cofactor is completely encompassed by the α-subunit, whereas the P-cluster pair occurs at the interface between α- and β-subunits. Structural similarities are apparent between nitrogenase and other electron transfer systems, including hydrogenases and the photosynthetic reaction centre
