• PubMed Abstract: 
  

  The crystal structure of recombinant rabbit interferon-gamma was solved by the multiple isomorphous replacement technique at 2.7-A resolution and refined to a crystallographic R-factor of 26.2%. The interferon crystallizes with one-half of the functional dimer in the asymmetric unit, with the two polypeptide chains of the dimer related by a crystallographic 2-fold symmetry axis. The structure is predominantly alpha-helical with extensive interdigitation of the alpha-helical segments of the two polypeptide chains.
