Figure 2.
The distribution of electrostatic potential at the solvent-accessible surface of a lysozyme molecule at pH = 7.8; kB, Boltzmann constant; T, temperature; and e, elementary charge. The Protein Data Bank (PBD) structure file PDB: 2VB1 was used. The protonation state of each acid or basic residue was evaluated at the chosen pH with PROPKA 3.0 (propka.org). The electrostatic map was computed online with the Adaptive Poisson-Boltzmann Solver and drawn using the software PyMOL (www.pymol.org). To see this figure in color, go online.
