AB  - Tumour necrosis factor    is a trimeric molecule, each subunit of which
      consists of an antiparallel beta-sandwich. Individual subunits from the
      trimer by a novel edge-to-face packing of beta-sheets. A comparison of the
      subunit fold with that of other proteins reveals a remarkable similarity
      to the 'jelly-roll' structural motif characteristic of viral coat
      proteins.
