Beschreibung:
The x-ray crystal structure of recombinant human interferon-gamma has been determined with the use of multiple-isomorphous-replacement techniques. Interferon-gamma, which is dimeric in solution, crystallizes with two dimers related by a noncrystallographic twofold axis in the asymmetric unit. The protein is primarily alpha helical, with six helices in each subunit that comprise approximately 62 percent of the structure; there is no beta sheet. The dimeric structure of human interferon-gamma is stabilized by the intertwining of helices across the subunit interface with multiple intersubunit interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ealick, S E -- Cook, W J -- Vijay-Kumar, S -- Carson, M -- Nagabhushan, T L -- Trotta, P P -- Bugg, C E -- CA-13148/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1991 May 3;252(5006):698-702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Alabama, Birmingham 35294.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1902591" target="_blank"〉PubMed〈/a〉
