[0012] The method of the present invention will be described in detail below as an example for identifying phosphorylation-specific sites of protein kinases, including the following steps:
[0013] a) Select 629 kinds of three-dimensional property parameters of 20 kinds of natural amino acids, including Randic molecular profile parameters, geometric characteristic parameters, radial basis function descriptors (RDF) based on different atomic distances, molecular structure characterization based on electric diffraction (MoRSE) ) obtained descriptor, weighted whole invariant molecular (WHIM) descriptor and geometric, topological and atomic weight set (GETAWAY) parameters.
[0014] Principal component analysis is used to process 629 property parameters, and 12 principal components are obtained, which accumulatively explain 95.82% of the variance of the original data matrix (20×629). The scores of each principal component are shown in Table 1. Therefore, the 12 principal component s...
