It is a significant issue to find similar proteins from a large scale of protein database efficiently. This paper presents a new algorithm of protein sequence which is based on fractal dimension and wavelet transform. A hybrid method consisting fractal dimension calculation, discrete wavelet transform and sliding window are applied to generate a new encoding feature. Through the computation between the feature vectors, we can obtain the distance matrix and the phylogenic tree can be constructed.We apply this approach by analyzing the ND5 (NADH dehydrogenase subunit 5) protein dataset. The experimental results show that the proposed model is more accurate than the existing ones such as Su's model, Zhang's model and Yao's model, and it is consistent with the result generated from MEGA software and some known facts.
