Comparing Crystallographic and Solution Structures of Nitrogenase Complexes

Abstract

A low-resolution structure from X-ray scattering data of Kp1•(ADP•AlF-_4•Kp2)2 predicted a significant change in the iron protein (Kp2) upon complex formation. This has been subsequently confirmed by the crystallographic structure of the complex in the Av system. New scattering results are provided to demonstrate the similarity of this complex in the two species.
