Abstract
We present three novel exclusively heteronuclear 5D (13)C direct-detected NMR experiments, namely (H(N-flip)N)CONCACON, (HCA)CONCACON and (H)CACON(CA)CON, designed for easy sequence-specific resonance assignment of intrinsically disordered proteins (IDPs). The experiments proposed have been optimized to overcome the drawbacks which may dramatically complicate the characterization of IDPs by NMR, namely the small dispersion of chemical shifts and the fast exchange of the amide protons with the solvent. A fast and reliable automatic assignment of ?-synuclein chemical shifts was obtained with the Tool for SMFT-based Assignment of Resonances (TSAR) program based on the information provided by these experiments.

TSAR: a program for automatic resonance assignment using 2D cross-sections of high dimensionality, high-resolution spectra
TSAR: a program for automatic resonance assignment using 2D cross-sections of high dimensionality, high-resolution spectra Abstract While NMR studies of proteins typically aim at structure, dynamics or interactions, resonance assignments represent in almost all cases the initial step of the analysis. With increasing complexity of the NMR spectra, for example due to decreasing extent of ordered structure, this task often becomes both difficult and time-consuming, and the recording of high-dimensional data with high-resolution may be essential. Random sampling of the evolution time space,...

4D Non-uniformly sampled HCBCACON and 1J(NCα)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins
4D Non-uniformly sampled HCBCACON and 1J(NCα)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins Abstract A pair of 4D NMR experiments for the backbone assignment of disordered proteins is presented. The experiments exploit 13C direct detection and non-uniform sampling of the indirectly detected dimensions, and provide correlations of the aliphatic proton (Hα, and Hβ) and carbon (Cα, Cβ) resonance frequencies to the protein backbone. Thus, all the chemical shifts regularly used to map the transient...

High dimensional and high resolution pulse sequences for backbone resonance assignment of intrinsically disordered proteins
High dimensional and high resolution pulse sequences for backbone resonance assignment of intrinsically disordered proteins Abstract Four novel 5D (HACA(N)CONH, HNCOCACB, (HACA)CON(CA)CONH, (H)NCO(NCA)CONH), and one 6D ((H)NCO(N)CACONH) NMR pulse sequences are proposed. The new experiments employ non-uniform sampling that enables achieving high resolution in indirectly detected dimensions. The experiments facilitate resonance assignment of intrinsically disordered proteins. The novel pulse sequences were successfully tested using δ subunit (20 kDa) of Bacillus subtilis RNA polymerase...

Extension of the HA-detection based approach: (HCA)CON(CA)H and (HCA)NCO(CA)H experiments for the main-chain assignment of intrinsically disordered proteins
Extension of the HA-detection based approach: (HCA)CON(CA)H and (HCA)NCO(CA)H experiments for the main-chain assignment of intrinsically disordered proteins Abstract Extensive resonance overlap exacerbates assignment of intrinsically disordered proteins (IDPs). This issue can be circumvented by utilizing 15N, 13C� and 1HN spins, where the chemical shift dispersion is mainly dictated by the characteristics of consecutive amino acid residues. Especially 15N and 13C� spins offer superior chemical shift dispersion in comparison to 13Cα and 13Cβ spins. However, HN-detected experiments...

Sparsely-sampled High-resolution 4-D Experiments for Efficient Backbone Resonance Assignment of Disordered Proteins
Sparsely-sampled High-resolution 4-D Experiments for Efficient Backbone Resonance Assignment of Disordered Proteins Publication year: 2011 Source: Journal of Magnetic Resonance, In Press, Accepted Manuscript, Available online 4 January 2011</br> Jie, Wen , Jihui, Wu , Pei, Zhou</br> Intrinsically disordered proteins (IDPs) play important roles in many critical cellular processes. Due to their limited chemical shift dispersion, IDPs often require four pairs of resonance connectivities (H?, C?, C? and CO) for establishing sequential backbone assignment. Because most conventional 4-D...

13C-direct detected NMR experiments for the sequential J-based resonance assignment o
Abstract We present here a set of 13C-direct detected NMR experiments to facilitate the resonance assignment of RNA oligonucleotides. Three experiments have been developed: (1) the (H)CC-TOCSY-experiment utilizing a virtual decoupling scheme to assign the intraresidual ribose 13C-spins, (2) the (H)CPC-experiment that correlates each phosphorus with the C4â?² nuclei of adjacent nucleotides via J(C,P) couplings and (3) the (H)CPC-CCH-TOCSY-experiment that correlates the phosphorus nuclei with the respective C1â?²,H1â?² ribose signals. The experiments were applied to two RNA hairpin structures....

HA-detected experiments for the backbone assignment of intrinsically disordered prote
Abstract We propose a new alpha proton detection based approach for the sequential assignment of natively unfolded proteins. The proposed protocol superimposes on following features: HA-detection (1) enables assignment of natively unfolded proteins at any pH, i.e., it is not sensitive to rapid chemical exchange undergoing in natively unfolded proteins even at moderately high pH. (2) It allows straightforward assignment of proline-rich polypeptides without additional proline-customized experiments. (3) It offers more streamlined and less ambiguous assignment based on solely intraresidual...
