Figure 9. Comparison of the electrostatic molecular surfaces around the haem crevices of A. suum (A) and bovine (B) cytochrome b₅, and A. suum model (C) and horse metmyoglobins (D) (PDB code 1WLA).

The electrostatic potential mapped on the protein surface was calculated using APBS [51]. A positive potential is indicated in blue, and a negative one is indicated in red.
