The crystal structure of Satellite tobacco mosaic virus (STMV) at 1.4 Å resolution represents the highest resolution and most precise native virus structure, utilizing more than twice as many reflections in refinement as were used for the previous STMV model. New details regarding the multiple ion arrangement on fivefold axes, the disposition of the `free' nucleotide, alternate conformations of amino-acid side chains and the distortion of the capsid from strict icosahedral symmetry have emerged.
