Abstract
Knowledge of RNA structure, either in isolation or in complex, is fundamental to understand the mechanism of cellular processes. Solid‐state NMR (ssNMR) is applicable to high molecular‐weight complexes and does not require crystallization; thus, it is well‐suited to study RNA as part of large multicomponent assemblies. Recently, we solved the first structures of both RNA and an RNA‐protein complex by ssNMR using conventional 13C‐ and 15N‐detection. This approach is limited by the severe overlap of the RNA peaks together with the low sensitivity of multidimensional experiments. Here, we overcome the limitations in sensitivity and resolution by using 1H‐detection at fast MAS rates. We develop experiments that allow the identification of complete nucleobase spin‐systems together with their site‐specific base pair pattern using sub‐milligram quantities of one uniformly labelled RNA sample. These experiments provide rapid access to RNA secondary structure by ssNMR in protein‐RNA complexes of any size.

Abstract
Solid‐state NMR (ssNMR) is applicable to high molecular‐weight (MW) protein assemblies in a non‐amorphous precipitate. The technique yields atomic resolution structural information on both soluble and insoluble particles without limitations of MW or requirement of crystals. Herein, we propose and demonstrate an approach that yields the structure of protein–RNA complexes (RNP) solely from ssNMR data. Instead of using low‐sensitivity magnetization transfer steps between heteronuclei of the protein and the RNA, we measure paramagnetic relaxation enhancement effects elicited on the RNA by a paramagnetic tag coupled to the protein. We demonstrate that this data, together with chemical‐shift‐perturbation data, yields an accurate structure of an RNP complex, starting from the bound structures of its components. The possibility of characterizing protein–RNA interactions by ssNMR may enable applications to large RNP complexes, whose structures are not accessible by other methods.

Abstract
Obtaining unambiguous resonance assignments remains a major bottleneck in solid-state NMR studies of protein structure and dynamics. Particularly for supramolecular assemblies with large subunits (>150 residues), the analysis of crowded spectral data presents a challenge, even if three-dimensional (3D) spectra are used. Here, we present a proton-detected 4D solid-state NMR assignment procedure that is tailored for large assemblies. The key to recording 4D spectra with three indirect carbon or nitrogen dimensions with their inherently large chemical shift dispersion lies in the use of sparse non-uniform sampling (as low as 2 %). As a proof of principle, we acquired 4D (H)COCANH, (H)CACONH, and (H)CBCANH spectra of the 20 kDa bacteriophage tail-tube protein gp17.1 in a total time of two and a half weeks. These spectra were sufficient to obtain complete resonance assignments in a straightforward manner without use of previous solution NMR data.

Abstract
The icosahedral bacteriophage T7 is a 50 MDa double-stranded DNA (dsDNA) virus that infects Escherichia coli. Although there is substantial information on the physical and morphological properties of T7, structural information, based mostly on Raman spectroscopy and cryo-electron microscopy, is limited. Here, we apply the magic-angle spinning (MAS) solid-state NMR (SSNMR) technique to study a uniformly (13)C and (15)N labeled wild-type T7 phage. We describe the details of the large-scale preparation and purification of an isotopically enriched phage sample under fully hydrated conditions, and show a complete (13)C and a near-complete (15)N nucleotide-type specific assignment of the sugar and base moieties in the 40 kbp dsDNA of T7 using two-dimensional (13)C-(13)C and (15)N-(13)C correlation experiments. The chemical shifts are interpreted as reporters of a B-form conformation of the encapsulated dsDNA. While MAS SSNMR was found to be extremely useful in determining the structures of proteins in native-like environments, its application to nucleic acids has lagged behind, leaving a missing (13)C and (15)N chemical shift database. This work therefore expands the (13)C and (15)N database of real B-form DNA systems, and opens routes to characterize more complex nucleic acid systems by SSNMR.

Abstract
Isotope labeling has revolutionized NMR studies of small nucleic acids, but to extend this technology to larger RNAs, site-specific labeling tools to expedite NMR structural and dynamics studies are required. Using enzymes from the pentose phosphate pathway, we coupled chemically synthesized uracil nucleobase with specifically (13) C-labeled ribose to synthesize both UTP and CTP in nearly quantitative yields. This chemoenzymatic method affords a cost-effective preparation of labels that are unattainable by current methods. The methodology generates versatile (13) C and (15) N labeling patterns which, when employed with relaxation-optimized NMR spectroscopy, effectively mitigate problems of rapid relaxation that result in low resolution and sensitivity. The methodology is demonstrated with RNAs of various sizes, complexity, and function: the exon splicing silencer 3 (27 nt), iron responsive element (29 nt), Pro-tRNA (76 nt), and HIV-1 core encapsidation signal (155 nt).
