Protein Structure Class Analysis Based on Multifractal and Quotient Space

The multifractal spectrum of protein feature sequences was computed and analyzed with the multifractal. The parameters of multifractal spectra were used to describe hierarchically refined structure of protein feature sequences and pop out the singularity of local sequences. And with using quotient space granularity computing theory power gene α of multifractal was chosen wilder. Constructing 2D space , and it presented good efficiency in structure classing, which is favor of predicting protein structure class.
