The Multifractal Properties of Signal Peptides

摘要：

We analyzed the generalized Hurst exponents for the amino acid sequences of proteins and secretory signal peptides used the multifractal detrended fluctuantion analysis (MF-DFA) method. The numeralization of the amino acid seqnences was completed according to the three amino acid indice: EIIP, polarity and accessible surface area. The results show that the proteins sequences have multifractal properties.The generalized Hurst exponents h(q) can divide the proteins in the special set into several classes.
