    Prediction of Four Kinds of Simple Supersecondary Structures in Protein by Using Chemical Shifts by Feng Yonge

    Published 2014-01-01
    “…In this study, a novel model is presented to predict protein supersecondary structure by use of chemical shifts (CSs) information derived from nuclear magnetic resonance (NMR) spectroscopy. Using these CSs as inputs of the method of quadratic discriminant analysis (QD), we achieve the overall prediction accuracy of 77.3%, which is competitive with the same method for predicting supersecondary structures from amino acid compositions in threefold cross-validation. …”
