Density bumps from hydrogen atoms enable correct rotamer assignment. Densities for the hydrogens emanating from the nitro­gen atoms of (a) glutamines and (b) asparagines enable discrimination between incorrect (left) and correct (right) orientations of the amide group in the density. The density for the three hydrogen atoms in Thr441 visualized in (c) side and (d) end-on views allows assignment of the rotamer of threonines because of the triangular shape of the projection viewed perpendicular to the plane of the three hydrogen atoms.
