Intrinsically disordered proteins: A conversation with Rohit Pappu

The earliest clue was that some protein segments didn't show up in X-ray crystallography or NMR studies, the standard ways of studying protein structure. By the 1990s people who studied how proteins interact with DNA had noticed the proteins often ...

4D Non-uniformly sampled HCBCACON and 1J(NCÎ±)-selective HCBCANCO experiments for the sequential assignment and chemical shift analysis of intrinsically disordered proteins 4D Non-uniformly sampled HCBCACON and 1J(NCÎ±)-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 (HÎ±, and HÎ²) and carbon (CÎ±, CÎ²) resonance frequencies to the protein backbone. Thus, all the chemical shifts regularly used to map the transient...	nmrlearner	Journal club	0	05-17-2012 08:40 AM
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 Î´ subunit (20 kDa) of Bacillus subtilis RNA polymerase...	nmrlearner	Journal club	0	02-21-2012 03:40 AM
Paramagnetic relaxation enhancement to improve sensitivity of fast NMR methods: application to intrinsically disordered proteins Paramagnetic relaxation enhancement to improve sensitivity of fast NMR methods: application to intrinsically disordered proteins Abstract We report enhanced sensitivity NMR measurements of intrinsically disordered proteins in the presence of paramagnetic relaxation enhancement (PRE) agents such as Ni2+-chelated DO2A. In proton-detected 1H-15N SOFAST-HMQC and carbon-detected (H-flip)13CO-15N experiments, faster longitudinal relaxation enables the usage of even shorter interscan delays. This results in higher NMR signal intensities per units of experimental time, without adverse line...	nmrlearner	Journal club	0	10-21-2011 10:04 PM

Bioinformatics. 2011 Mar 3; Authors: Tamiola K, Mulder FA SUMMARY: We describe here the ncIDP-assign extension for the popular NMR assignment programme SPARKY, which aids in the sequence-specific resonance assignment of intrinsically disordered proteins (IDPs). The assignment plugin greatly facilitates the effective matching of a set of...	nmrlearner	Journal club	0	03-05-2011 01:02 PM
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, 13Câ?² and 1HN spins, where the chemical shift dispersion is mainly dictated by the characteristics of consecutive amino acid residues. Especially 15N and 13Câ?² spins offer superior chemical shift dispersion in comparison to 13CÎ± and 13CÎ² spins. However, HN-detected experiments...	nmrlearner	Journal club	0	01-29-2011 05:31 AM
Random coil chemical shift for intrinsically disordered proteins: effects of temperature and pH Random coil chemical shift for intrinsically disordered proteins: effects of temperature and pH Abstract Secondary chemical shift analysis is the main NMR method for detection of transiently formed secondary structure in intrinsically disordered proteins. The quality of the secondary chemical shifts is dependent on an appropriate choice of random coil chemical shifts. We report random coil chemical shifts and sequence correction factors determined for a GGXGG peptide series following the approach of Schwarzinger et al. (J Am Chem Soc 123(13):2970â??2978, 2001). The chemical shifts are...	nmrlearner	Journal club	0	01-17-2011 02:40 AM
