Title: NMR AND MOLECULAR MODELING REVEAL THAT DIFFERENT HYDROGEN BONDING PATTERNS ARE POSSIBLE FOR GU PAIRS: ONE HYDROGEN BOND FOR EACH GU PAIR IN R(GGCGUGCC)2 AND TWO FOR EACH GU PAIR IN R(GAGUGCUC)2 Molecular Description: 5'-R(GpApGpUpGpCpUpC)-3' Nucleic Acid Sequence: Chains A,B: G A G U G C U C Primary Citation: Chen, X., McDowell, J.A., Kierzek, R., Krugh, T.R., Turner, D.H. Nuclear magnetic resonance spectroscopy and molecular modeling reveal that different hydrogen bonding patterns are possible for G.U pairs: one hydrogen bond for each G.U pair in r(GGCGUGCC)(2) and two for each G.U pair in r(GAGUGCUC)(2). Biochemistry , 39, pp. 8970 - 8982, 2000.
