Methods for identifying ligand binding sites in a biomolecule

Abstract From the Canadian patent

Methods of identifying ligand binding sites in a target molecule such as a polynucleotide or polypeptide, as well as methods for determining whether a particular site in a target molecule is at or near the ligand binding site are provided. Ligand binding affinities corresponding to both the target molecule and a modified version thereof are compared preferably using mass , spectral analysis. The modified molecules or test molecules, incorporate a , modification capable of modulating ligand binding affinity when located at or near the ligand binding sites. Binding site information is derived from the known position of the modification.
