| + | The model of <scene name='10/1068508/Tetrahedron/2'>Tetrahedron A</scene> is a predicted structure with no missing atoms. In contrast, the Cryo-EM models (see above) have [[resolutions]] of 4 to 7 Ås;, with over half of their amino acids modeled as alanines, and hence missing most sidechain atoms. | ||
