Several oligonucleotides of defined sequence were synthesized using 2'(3')-O-dihydrocinnamoyl-nucleoside 5'-diphosphates (DHC-NDP) as substrates for polynucleotide phosphorylase [EC 2. 7. 7. 8] from Thermus thermophilus. The enzyme catalyzed the transfer of one nucleotidyl residue from each of the 2'(3')-O-dihydrocinnamoyl esters of CDP, UDP, and GDP to the 3'-terminus of the primer triadenosine diphosphate, (Ap)2A. The products were shown to be (Ap)2C, (Ap)3U, and (Ap)8G by enzymatic analysis.
