The mode of binding between Plk1 PBD and its high-affinity ligand, 4j. a Electrostatic surface representation of the Plk1 PBD in complex with 4j. Surface colors represent electrostatic potentials with red (negative), blue (positive), and white (neutral). For 4j, oxygen and nitrogen atoms are colored in red and blue, respectively. The alkylphenyl moiety is indicated in violet. The phosphorylated (red)-T residue is shown. b A schematic diagram showing 4j and its three elements, which are critical for Plk1 PBD binding. PLHSpT is shown in single letters except for phosphorylated (red)-T. The alkylphenyl moiety of 4j is indicated in violet
