      The iron protein from Azotobacter vinelandii nitrogenase has been crystallized in the reduced form. The needle-shaped crystals are in space group P2(1)2(1)2 (a = 94.6 A, b = 179.9 A, c = 74.1 A) and diffract to at least 3.5-A resolution. Five or six Fe-protein monomers are present in the asymmetric unit.
