Structure of the hOAS1●dsRNA●dATP ternary complex. The complex is shown in two orientations related by 90° rotation. Protein is shown as ribbons; dsRNA (purple) and dATP (light blue) are shown as molecular surfaces. Two Mg2+ ions are shown as spheres (green). dsRNA is bound at the junction of the N lobe and the C lobe of hOAS1.
