Electrostatic potentials. Electrostatic isopotential lines (± [0.01, 0.03, 0.05, 0.08, 0.1] kcal/mol/e) for chain A (panel A) and chain B (panel B) of HFBI. Isolines are shown for the cross-section passing through the center of the protein. Three-dimensional isosurfaces at 0.01 kcal/mol/e are shown in the insets. The electrostatic potential was computed at pH 5 and 50 mM IS by solving the linearized Poisson Boltzmann equation using UHBD  (see Methods Section for details).
