An example of the electron density (cyan chicken wire) for residues on one side of the active site. The map was calculated with (|2Fo − Fc|), αc coefficients and contoured at the 1.5σ level. The residues are depicted in stick mode and coloured according to atom type; C, grey; N, blue; O, red. The real-space fit residual (RSF; Jones et al., 1991 ![]() |
