The spacing distance of amino acids is used to study the relationship between the primary structure and structural classification of large proteins. Rescaled-range (R/S) analysis was adopted to examine long-range correlation property of proteins. And multifractal property is then discussed by the spacing distance of amino acids. A classification of proteins by assigning to each sequence a point in two-dimensional space(\Delta\alpha, H) is given to construct a phylogenetic tree. This result is shown to be reasonably satisfactory to \alpha + \beta class.
