Figure 4: Electrostatic potential on the molecular surfaces buried in the interface between Cln1/2 and Cdc28. Electrostatic Complementarities on the buried molecular surface of (a-1) the flip state of Cdc28 (left) and Cln1 (right), (a-2) the flop state of Cdc28 (left) and Cln1 (right), (b-1) the flip state of Cdc28 (left) and Cln2 (right), (b-2) the flop state of Cdc28 (left) and Cln2 (right) generated by its own charges. Blue is positive, white is neutral and red is negative charged region.
