RAPID DISPLAY METHOD IN TRANSLATIONAL SYNTHESIS OF PEPTIDE

摘要

Provided are linkers suitable for preparing a conjugate of a nucleic acid and a peptide as a translation product thereof in a reconstituted cell-free translation system in genotype-phenotype mapping (display methods), said linkers comprising a single-stranded structure region having a side chain base pairing with the base at the 3'-end of an mRNA at one end and a peptidyl acceptor region containing an amino acid attached to an oligo RNA consisting of a nucleotide sequence of ACCA via an ester bond at the other end, characterized in that the ester bond is formed by using an artificial RNA catalyst. Also provided are display methods using [mRNA] - [linker] - [peptide] conjugates assembled via such linkers.
