Details METHOD--SITUS (CHACON ET AL, 2002 J. MOL. BIOL. 317,375-394) WAS USED TO FIT THE X-RAY STRUCTURE OF REOVIRUS POLYMERASE (TAO ET AL. 2002 CELL 111, 733-745) (PDB CODE 1N35) INTO THE EM DENSITY OF THE 7.6-A RESOLUTION MAP OF REOVIRUS VIRIONS. THE COORDINATES OF THE FITTED REOVIRUS POLYMERASE WERE ALIGNED TO THE X-RAY STRUCTURE OF REOVIRUS CORE (REINISCH ET AL. 2000 NATURE 404,960-967) (PDB ENTRY 1EJ6). ALL MATRICES FOR BUILDING AN ICOSAHEDRON CAN BE FOUND IN 1EJ6.
