Method for constructing libraries of non-standard peptide compounds comprising N-methyl amino acids and other special (non-standard) amino acids and method for searching and identifying active species
Method for constructing libraries of non-standard peptide compounds comprising N-methyl amino acids and other special (non-standard) amino acids and method for searching and identifying active species
A method for screening a non-standard peptide compound in the peptide library that binds to the target substance, comprising the steps: (i) preparing a non-standard peptide library wherein a special (non-standard) amino acid is randomly incorporated into the peptide sequence by a cell-free (in vitro) translation system comprising a tRNA acylated by a special (non-standard) amino acid; (ii) bringing the obtained peptide library in contact with a target substance; and (iii) selecting a non-standard peptide that binds to the target substance as an active peptide.
