Abstract: Modified self-consistent harmonic approach was employed to calculate the probability for the disruption of each individual hydrogen bonds (H bonds) in x-ray crystal structure of several proteins. The computed probability for 82% of intraprotein and water-protein H bonds studied were found to be roughly consistent with estimated free energies from protein engineering and hydrogen exchange experiments. Hydrogen bonds have been proposed as part of a stereochemical code for protein folding. Proteins fold into unique three-dimensional structures; therefore those bonds involved in the folding code are expected to be stable. We have applied this method to tens of hydrogen bonds in a protein assumed to be involved in the folding code of a protein. 58% of these H bonds were found to have a lower disruption probability (- 1.8 kcal/mol). Our results showed that modified self-consistent harmonic approach might be explored as a method supplement to existing methods in analysis of hydrogen bonds in proteins. © 2001 John Wiley & Sons, Inc.
