Non-classical hydrogen bonds in interleukins: the role of C-H...O interactions.
The role of classical hydrogen bonds in the structural stability of biological macro-molecules is well understood. In the present study, we explore the influence of C-H...O interactions in relation to other environmental preferences in interleukins. Main chain-main chain interactions are predominant. Pro residues might stabilize helices and strands by C-H...O H-bonds in interleukins. Majority of the C-H...O interacting residues were solvent exposed. 62% of C-H...O interactions was long-range interactions. The results presented in this study might be useful for structural stability studies in interleukins.
