Abstract
Defining discontinuous antigenic epitopes remains a substantial challenge, as exemplified by the case of lipid transfer polyproteins, which are common pollen allergens. Hydrogen/deuterium exchange monitored by NMR can be used to map epitopes onto folded protein surfaces, but only if the complex rapidly dissociates. Modifying the standard NMR-exchange measurement to detect substoichiometric complexes overcomes this time scale limitation and provides new insights into recognition of lipid transfer polyprotein by antibodies. In the future, this new and exciting development should see broad application to a range of tight macromolecular interactions.

Abstract
Identifying an epitope, the region of the antigen in contact with an antibody, is useful in both basic and pharmaceutical research, as well as in vaccine design. Solution NMR spectroscopy is particularly well suited to the residue...

Measuring 1HN temperature coefficients in invisible protein states by relaxation dispersion NMR spectroscopy
Abstract A method based on the Carr-Purcell-Meiboom-Gill relaxation dispersion experiment is presented for measuring the temperature coefficients of amide proton chemical shifts of low populated â??invisibleâ?? protein states that exchange with a â??visibleâ?? ground state on the millisecond time-scale. The utility of the approach is demonstrated with an application to an I58D mutant of the Pfl6 Cro protein that undergoes exchange between the native, folded state and a cold...

Journal of Biomolecular NMR; 2008; 41(3); pp 113 - 120
Abstract:
Currently the main focus of structural biology is the determination of static three-dimensional representations of biomolecules that for the most part correspond to low energy (ground state) conformations. However, it is becoming increasingly well recognized that higher energy structures often play important roles in function as well. Because these conformers...
