Figure 1

Schematic representation of the interaction between CLR01 and Lys. CLR01 is depicted in blue and Lys in black. The Coulombic attraction between a negatively charged phosphate group at the bridgehead of CLR01 and the positively charged ϵ-NH3 + group of Lys is illustrated in cyan. The binding is stabilized also by hydrophobic interaction between the hydrocarbon side arms of CLR01 and the butylene chain of the Lys.
