Figure 6
Charge-density analysis of the E222Q variant. (a) The residual density in a slice of the chromophore plane after ISAM refinement. (b) The static deformation density in a slice of the chromophore plane after MAM refinement. The contour intervals are 0.05 e Å−3. Positive, blue lines; negative, red broken lines. The intervals are only colored in blue. (c) AIM charge values are shown in parentheses on each atom, while topological bond orders are given along each covalent bond. H atoms and their positive charges are not shown.
