Two side chains pulled too close down into their nubbins of density. (a) In PDB entry 2qls at 3.5 Å, with backbone clashes (red spikes), a rotamer outlier (gold) and a Cβ deviation (magenta ball). (b) In PDB entry 2dn2 at 1.25 Å resolution, in clear 2Fo − Fc density with relaxed, spread-out rotamers and no outliers. |
