[0017] In order to better understand the technical content of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.
[0018] figure 1 A schematic diagram of the system structure of the prediction method of the present invention is given. combine figure 1 As shown, according to an embodiment of the present invention, a method for predicting protein-ligand binding sites based on sampling learning includes the following steps:
[0019] First, use the PSI-BLAST and PSIPRED programs to obtain the evolutionary information matrix (Position Specific Scoring Matrix, PSSM) and secondary structure prediction probability matrix (Predicted Secondary Structure, PSS) of the training protein respectively; Construct the eigenvector of each amino acid residue with the secondary structure prediction probability matrix, and then serially combine the eigenvectors of the above two kinds of information to obtain the final eigenv...
