Figure 2. Figure 2. The Central Cavity of MPP(a) Electrostatic surface representation of MPP contoured at ±15 kcal calculated by GRASP [58]. Positive charge is shown as blue and negative charge as red. The flexible loop (residues a284-a301) is circled.(b) A cutaway view of the surface representation of MPP revealing the electrostatic potential of the central cavity
