Embodiment Construction
[0027] The method for rapid screening of amino acid peptide aptamers based on molecular docking technology includes the following steps:
[0028] (1) Determine target metabolites (amino acids);
[0029] (2) Obtain a library of peptides potentially binding to the target: with amino acids as the target, select and download from the protein database (NCBI) and human (1679), commonly used experimental animals mouse (6940), rat (4020), The primary structure of the protein related to amino acid metabolism in pig (1546 entries) is its amino acid sequence. Link all the amino acid sequences into a long peptide chain; set the length of the short peptide chain to 8 amino acid residues, cut and remove the repeated sequences to obtain the non-redundant peptide library Library2, with a storage capacity of about 2.85 million peptides;
[0030] (3) Using autodock, the molecules in the known three-dimensional structure database in the peptide library Library2 are placed one by one at the acti...
