Abstract

In this paper we use local Holder exponents to capture local patterns in protein sequences. The numerical sequence of a protein based on a 6-letters model of amino acids is considered as a time series, then its local Hölder exponents are estimated using the wavelet transform. The probability density of local Hölder exponents is then calculated. The probability density values are then taken as features for a perceptron constructed by Neural Network Toolbox in Matlab to classify proteins from the all-α, all-β, α + β and α/β protein structure classes. Numerical results indicate that all selected large proteins can be classified with 100% accuracies.
