Figure 1
3D Fourier electrostatic potential maps of lysozyme at resolutions dmin = 1–4 Å, with an atomic structure shown only for a short helical fragment. The maps are calculated using TAAM without and with accounting for B factors, i.e. thermal smearing effects (magenta and pink, respectively) and using IAM without and with B factors (dark green and light green, respectively). Two chosen, oppositely charged amino acids are indicated with arrows. All maps are shown at the 2σ contour level.
