Atlas of Side-Chain and Main-Chain Hydrogen Bonding

by Ian McDonald and Janet M Thornton

WWW Edition December 1994, original edition April 1993

This document is a graphical summary of hydrogen bonding in a dataset of high-resolution protein structures. It shows the distributions of the frequencies and geometries of hydrogen bonds formed by main-chain and side-chain donors and acceptors. It is hoped that it will serve as a record of the hydrogen bonding patterns of the standard hydrogen bonding groups for molecular modellers and crystallographers who would like to know whether the hydrogen bonding in their model is normative.
