Analysis of Protein Structure in Solution by Two-Dimensional NMR Spectroscopy: 2D-1H NMR Investigation of Ribonuclease T1 and Its Complexes with 2′- and 3′-Guanosine Monophosphates

Abstract

Two-dimensional (2 D) NMR spectroscopy may be used to study the tertiary structure of proteins and nucleic acids [28]. This NMR approach to determining the structure of biological macromolecules has some advantages over the conventional method using x-ray crystallography: 1) NMR spectroscopy can be applied to proteins that cannot be crystallized; 2) The tertiary structure of proteins or nucleic acids can be obtained under varying conditions such as pH, temperature, or inhibitor concentration; 3) NMR parameters may provide information on the dynamics of protein conformation, so that exchange processes and molecular flexibility may be studied.
