✦ Synopsis

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 and geometry of sulfur-containing hydrogen bonds. This information should be of interest to experimentalists and theoreticians interested in protein structure and protein engineering.

## Abstract The PCILO method was used to study systems with the following types of intermolecular hydrogen bonds, involving 2nd row atoms: N…︁HS, S…︁HS, N…︁HCl, Cl…︁HF, Cl…︁HCl, P…︁HN, P…︁HP, P…︁HF, S…︁HF. In all the cases calculated, the PCILO method yields an accurate qualitative descri
