Abstract: | Hydrogen/deuterium exchange in combination with mass spectrometry (H/D MS) is a sensitive technique for detection of changes
in protein conformation and dynamics. However, wide application of H/D MS has been hindered, in part, by the lack of computational
tools necessary for efficient analysis of the large data sets associated with this technique. We report a novel web-based
application for automatic analysis of H/D MS experimental data. This application relies on the high resolution of mass spectrometers
to extract all isotopic envelopes before correlating these envelopes with individual peptides. Although a fully automatic
analysis is possible, a variety of graphical tools are included to aid in the verification of correlations and rankings of
the isotopic peptide envelopes. As a demonstration, the rate constants for H/D exchange of peptides from rabbit muscle pyruvate
kinase are mapped onto the structure of this protein. |
