title: Conformation and recognition control of peptide ribonucleic acid containing pyrimidine/purine mixed sequence.
abstract: Peptide ribonucleic acids (PRNA), tethering 5'-amino-5'-deoxyribonucleoside as a recognition moiety for RNA/DNA, have been designed and synthesized, as a novel nucleic acid model. External switching of the recognition behavior of PRNA containing not only pyrimidine nucleobase but also purine nucleobase, with complementary oligomeric DNA/RNA has been demonstrated for the first time through both the orientational switching of the nucleobase of PRNA and electrostatic repulsion between borate ester anion of PRNA and phosphodiester anion of DNA/RNA, induced by added borates.
