C-H...O hydrogen bonds in the nuclear receptor RARgamma--a potential tool for drug selectivity.
Structure, 10:1197-1204, 2002

PubMed Abstract: 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.
