Abstract
The present invention provides methods for crystallographic structure determination employing hydrogen exchange analysis. Hydrogen exchange analysis is used to identify unstructured regions of a protein, and then hydrogen exchange analysis repeated after the protein is admixed with candidate agents and/or conditions that may induce structure in said identified unstructured regions. Agents that induce desired structure in the protein are then employed, admixed with the protein, in co-crystallization studies for structure determination. Hydrogen exchange analysis is performed by determining the quantity of isotope and/or rate of exchange of peptide amide hydrogen(s) with isotope on a labeled protein. Proteins with agent-induced decreases in unstructured regions, and thus improved hydrogen exchange structural maps, are optimal for high quality crystallization and structure determination.
