title: Studies by 1H nuclear magnetic resonance and distance geometry of the solution conformation of the alpha-amylase inhibitor tendamistat.
abstract: This is a preliminary report on the determination of the solution conformation of the alpha-amylase inhibitor Tendamistat by nuclear magnetic resonance and distance geometry calculations. A characterization is given of the complete polypeptide backbone fold and the side-chains of the presumed active site in this protein. These results are based on complete sequence-specific resonance assignments, a list of 401 distance constraints from nuclear Overhauser effects, 168 distance constraints from hydrogen bonds and disulphide bridges, and 50 torsion angle constraints from measurements of spin-spin coupling constants.
