  • Title: Mirror-image RNA that binds D-adenosine.
    Author: Klussmann S, Nolte A, Bald R, Erdmann VA, Fürste JP.
    Journal: Nat Biotechnol; 1996 Sep; 14(9):1112-5. PubMed ID: 9631061.
    Abstract:
    A 58-mer L-RNA ligand that binds to naturally occurring D-adenosine with a dissociation constant of 1.7 microM in solution was identified from a combinatorial library employing mirror-design. The corresponding D-RNA ligand shows identical binding affinity to L-adenosine. Reciprocal chiral specificity was also evident from ligand discrimination; the binding affinity of the L-RNA ligand for D-adenosine was 9000-fold greater than its affinity for L-adenosine and vice versa. While the D-RNA ligand was rapidly degraded in human serum, the L-RNA ligand displayed an extraordinary stability. This indicates the potential application of specifically designed L-RNA ligands as stable monoclonal antibody analogues and the development of highly stable L-ribozymes.
