Figure 5

Electrostatic potential surfaces of the proximal sides of cyt b5 (left) and CYP2B4 (right), showing the negatively charged convex surface of cyt b5 (PDB code: 2M33)24 and the positively charged concave surface of CYP2B4 (PDB code: 1SUO34).
The electrostatic potential surfaces were calculated using the PDB2PQR50,51 server and PyMOL52 with the APBS plugin 2.153.
