The role of metal ions is central to the stabilization of the structure and the working of proteins, nucleic acids, and peptide hormones. In particular metal ions are known to aid intramolecular proton transfer processes in biological systems, as discussed in the case of 2-(3'-hydroxy-2'- pyridyl)benzoxazole in the article on page 1316 by Pinggui Yi, Zhengjun Liu, Zhaoxu Wang, Xianyong Yu, Jiming Zhou, Bo Hou, and Qingzhong Li.
