The interaction of blood glucose with heme proteins plays a key role in inducing diabetes, a serious disease threatening human health. In this study, we investigated the non-covalent interaction between glucose and myoglobin (Mb), both theoretically and experimentally, using molecular dynamics (MD) simulation combined with spectroscopic studies. It revealed that glucoses can occupy the side pocket of Mb, and bind closely to one of the xenon cavities in Mb, by hydrogen bonding interactions with two propionate groups of heme as well as surrounding amino acids. These interactions alter the confor...
