Abstract

Progress in the structural biology of proteins comes from both experimental and theoretical efforts. Computational methods are capable of delivering fast structural information, ranging from low-resolution protein structural class definition to high-quality information based on homology modeling. Experimental methods that concentrate on obtaining high-resolution information are hampered by inherent time cost, and lack the capacity to provide low-resolution structural information expediently. NMR spectroscopy is a powerful tool for obtaining high-resolution structural and dynamical details of molecules in the solution state. We have reviewed a number of semi-empirical methods for the fast identification of protein structures using NMR, emphasizing those that explore the degree to which chemical shifts of a particular nuclear species in the protein backbone can be used as a low-resolution parameter that correlates with a variety of important structural features.
