Functionalized polystyrene supports for solid-phase synthesis of glycyl-, alanyl-, and isoleucyl-RNA conjugates as hydrolysis-resistant mimics of peptidyl-tRNAs

By Jessica Steger and Ronald Micura


RNA-peptide conjugates that mimic amino acid-charged tRNAs and peptidyl-tRNAs are of high importance for structural and functional investigations of ribosomal complexes. Here, we present the synthesis of glycyl-, alanyl-, and isoleucyladenosine modified solid supports that are eligible for the synthesis of stable 3′-aminoacyl- and 3′-peptidyl-tRNA termini with an amide instead of the natural ester linkage. The present work significantly expands the range of accessible peptidyl-tRNA mimics for ribosomal studies
