CRYSTAL STRUCTURE OF RECOMBINANT BOVINE INTERFERON-GAMMA AT 3.0 ANGSTROMS RESOLUTIONCRYSTAL STRUCTURE OF RECOMBINANT BOVINE INTERFERON-GAMMA AT 3.0 ANGSTROMS RESOLUTION
Structural highlights
Function[IFNG_BOVIN] Produced by lymphocytes activated by specific antigens or mitogens. IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. It is a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe three-dimensional crystal structure of recombinant bovine interferon-gamma was determined using the multiple isomorphous replacement method at 3.0 A and refined to an R factor of 19.2%. This protein crystallizes in space group P2(1)2(1)2(1) with unit-cell parameters of a = 42.8, b = 79.9 and c = 85.4 A. There is one functional dimer in the asymmetric unit. The two polypeptide chains are related by a non-crystallographic twofold symmetry axis. The secondary structure is predominantly alpha-helical with extensive interdigitation of the alpha-helical segments of the polypeptide chains that make up the dimer. The secondary structure, tertiary structure and topology of this molecule are identical to the previously reported structures of recombinant rabbit interferon-gamma and recombinant human interferon-gamma. The molecular topology is also similar to that of murine interferon-beta. These structural similarities strongly indicate the presence of a unique topological feature (fold) among gamma-interferons from different species, and also among the different classes of interferons. Structure of recombinant bovine interferon-gamma at 3.0 A resolution.,Samudzi CT, Rubin JR Acta Crystallogr D Biol Crystallogr. 1993 Nov 1;49(Pt 6):513-21.
