    Experiments for Correlating Quaternary Carbons in RNA Bases

  • Original language description

    The paper presents a set of triple-resonance two-dimensional experiments for correlating all quaternary carbons in RNA bases to one or more of the base protons. The experiments make use of either three-bond proton-carbon couplings and one selective INEPTstep (the long-range selective HSQC experiment) to transfer the magnetization between a proton and the carbon of interest and back, or they rely on one- and/or two-bond heteronuclear (the H(CN)C and H(N)C experiments) or carbon-carbon couplings (the H(C)C experiment) and multiple INEPT transfer steps. The effect of the large one-bond carbon-carbon coupling in t1 is removed by a constant time evolution or by a selective refocusing. The performance of the proposed approach is demonstrated on a 0.5 mM 25-mer RNA. The results show that the experiments are applicable to samples containing agents for weak molecular alignment. The design of the correlation experiments has been supported by ab initio calculations of scalar spin-spin couplings

    Experimenty pro korelaci kvarterních atomů uhlíku v bazích RNA

  • Czech description

    Článek uvádí nové heteronukleární 2D NMR experimenty pro korelaci všech kvarterních uhlíků v bázích RNA s jedním nebo více jádry vodíku. Experimenty jsou založeny na jedno, dvou nebo třívazebných interakcích a několikanásobných přenosech magnetizace. Štěpení signálu vlivem jednovazebné interakce uhlík-uhlík je odstraněno pomozí vývoje v konstantním čase nebo selektivní refokusací. Citlivost navrhovaných experimentů dovoluje naměřit spektra 0.5 mM 25-meru RNA za čtyři hodiny nebo méně. Experimenty jsou aplikovatelné i na vzorky v orietovaných fázích.
