  • Title: Quintets of uracil and thymine: a novel structure of nucleobase self-assembly studied by electrospray ionization mass spectrometry.
    Author: Qiu B, Liu J, Qin Z, Wang G, Luo H.
    Journal: Chem Commun (Camb); 2009 May 28; (20):2863-5. PubMed ID: 19436891.
    Abstract:
    ESI-MS and molecular dynamic calculations reveal that in the presence of K(+), Rb(+) and Cs(+), uracil, thymine and their homologues form self-assembled quintet structures that are stabilized by hydrogen bonding and ion dipole interactions.
