Intrachain hydrogen bonds are a hallmark of globular proteins. Traditionally, these involve oxygen and nitrogen atoms. The electronic structure of sulfur is compatible with hydrogen bond formation as well. We surveyed a set of 85 high-resolution protein structures in order to evaluate the prevalence

Over the last few years x-ray diffraction and nmr investigations have been reported for a variety of natural and synthetic peptides in order to enhance our understanding of the conformation of several amino acid side chains and especially those bearing functional groups such as hydroxyl, sulfhydryl,
Republic of Germany synopsis (L-Cys),, (L-LYS),, and (L-G~u), were studied by ir spectroscopy in terms of their degree of deprotonation or protonation. It is shown that structurally symmetrical, easily polarizable SH-S-+ -S--HS, N+H-N =N.--H+N, and OH---0-\* -0-HO hydrogen bonds are formed between t
