Arginine fork

Figure 4.3 The amino acid arginine and the arginine fork binding mode with phosphate anion residues.

The electrostatic potential is commonly used as a means to understand possible channels for a substrate to approach a host on the basis of electrostatic interactions. As an example Fig. 12.1 depicts the electrostatic potential of a biomimetic arginine fork studied by quantum chemical methods [14, 36]. This artifical argi-...
