ISOTYPE SELECTIVITY OF THE HUMAN RETINOIC ACID NUCLEAR RECEPTOR HRAR: THE COMPLEX WITH THE RARGAMMA-SELECTIVE RETINOID SR11254

Overview

Hydrogen bonds between polarized atoms play a crucial role in protein, interactions and are often used in drug design, which usually neglects the, potential of C-H...O hydrogen bonds. The 1.4 A resolution crystal, structure of the ligand binding domain of the retinoic acid receptor, RARgamma complexed with the retinoid SR11254 reveals several types of, C-H...O hydrogen bonds. A striking example is the hydroxyl group of the, ligand that acts as an H bond donor and acceptor, leading to a synergy, between classical and C-H...O hydrogen bonds. This interaction introduces, both specificity and affinity within the hydrophobic ligand pocket. The, similarity of intraprotein and protein-ligand C-H...O interactions, suggests that such bonds should be considered in rational drug design, approaches.
