Crystallization and preliminary X-ray diffraction studies of bovine recombinant immune interferon.
Reproducible conditions have been established for the crystallization of recombinant bovine immune interferon. Two cystalline forms of this protein were obtained. A tetragonal form, space group P422, with unit cell dimensions a = b = 59.0 A and c = 125.7 A and an orthorhombic form, space group P2(1)2(1)2(1), with unit cell dimensions a = 42.80 A, b = 79.90 A and c = 85.64 A were obtained under similar crystallization conditions. The orthorhombic form diffracts to 2.6 A resolution, contains a single interferon dimer in the asymmetric unit of structure and is suitable for X-ray diffraction analysis.
