Solid-state NMR [13C,15N] resonance assignments of the nucleotide-binding domain of a bacterial cyclic nucleotide-gated channel.

ABSTRACT: Channels regulated by cyclic nucleotides are key signalling proteins in several biological pathways. The regulatory aspect is conferred by a C-terminal cyclic nucleotide-binding domain (CNBD). We report resonance assignments of the CNBD of a bacterial mlCNG channel obtained using 2D and 3D solid-state NMR under Magic-angle Spinning conditions. A secondary chemical shift analysis of the 141 residue protein suggests a three-dimensional fold seen in earlier X-ray and solution-state NMR work and points to spectroscopic polymorphism for a selected set of resonances.

1H, 13C and 15N NMR assignments of cyclophilin LRT2 (OsCYP2) from rice.

Project description:Cyclophilins are enzymes that catalyze the isomerization of a prolyl-peptide bond and are found in both prokaryotes and eukaryotes. LRT2 (also known as OsCYP2) is a cyclophilin in rice (Oryza sativa), that has importance in lateral root development and stress tolerance. LRT2 is 172 amino acids long and has a molecular weight of 18.3 kDa. Here, we report the backbone and sidechain resonance assignments of 1H, 13C, 15N in the LRT2 protein using several 2D and 3D heteronuclear NMR experiments at pH 6.7 and 298 K. Our chemical shift data analysis predicts a secondary structure like the cytosolic wheat cyclophilin TaCypA-1 with 87.7% sequence identity. These assignments will be useful for further analysis in the NMR studies for function and structure of this enzyme.

1H, 15N and 13C backbone resonance assignments of the archetypal serpin ?1-antitrypsin.

Project description:Alpha(1)-antitrypsin is a 45-kDa (394-residue) serine protease inhibitor synthesized by hepatocytes, which is released into the circulatory system and protects the lung from the actions of neutrophil elastase via a conformational transition within a dynamic inhibitory mechanism. Relatively common point mutations subvert this transition, causing polymerisation of ?(1)-antitrypsin and deficiency of the circulating protein, predisposing carriers to severe lung and liver disease. We have assigned the backbone resonances of ?(1)-antitrypsin using multidimensional heteronuclear NMR spectroscopy. These assignments provide the starting point for a detailed solution state characterization of the structural properties of this highly dynamic protein via NMR methods.

1H, 13C and 15N resonance assignments of SARS-CoV main protease N-terminal domain.

Project description:The main protease (M(pro)) of severe acute respiratory syndrome coronavirus (SARS-CoV) plays an essential role in the extensive proteolytic processing of the viral polyproteins (pp1a and pp1ab), and it is an important target for anti-SARS drug development. SARS-CoV M(pro) is composed of a catalytic N-terminal domain and an ?-helical C-terminal domain linked by a long loop. Even though the N-terminal domain of SARS-CoV M(pro) adopts a similar chymotrypsin-like fold as that of piconavirus 3C protease, the extra C-terminal domain is required for SARS-CoV M(pro) to be enzymatically active. Here, we reported the NMR assignments of the SARS-CoV M(pro) N-terminal domain alone, which are essential for its solution structure determination.

1H, 13C and 15N NMR assignments of the C1A and C1B subdomains of PKC-delta.

Project description:The Protein Kinase C family of enzymes is a group of serine/threonine kinases that play central roles in cell-cycle regulation, development and cancer. A key step in the activation of PKC is translocation to membranes and binding of membrane-associated activators including diacylglycerol (DAG). Interaction of novel and conventional isotypes of PKC with DAG and phorbol esters occurs through the two C1 regulatory domains (C1A and C1B), which exhibit distinct ligand binding selectivity that likely controls enzyme activation by different co-activators. PKC has also been implicated in physiological responses to alcohol consumption and it has been proposed that PKC? (Slater et al. J Biol Chem 272(10):6167-6173, 1997; Slater et al. Biochemistry 43(23):7601-7609, 2004), PKC? (Das et al. Biochem J 421(3):405-413, 2009) and PKC? (Das et al. J Biol Chem 279(36):37964-37972, 2004; Das et al. Protein Sci 15(9):2107-2119, 2006) contain specific alcohol-binding sites in their C1 domains. We are interested in understanding how ethanol affects signal transduction processes through its affects on the structure and function of the C1 domains of PKC. Here we present the (1)H, (15)N and (13)C NMR chemical shift assignments for the Rattus norvegicus PKC? C1A and C1B proteins.

Intramolecular 1H-13C distance measurement in uniformly 13C, 15N labeled peptides by solid-state NMR.

Project description:A (1)H-(13)C frequency-selective REDOR (FS-REDOR) experiment is developed for measuring intramolecular (1)H-(13)C distances in uniformly (13)C, (15)N-labeled molecules. Theory and simulations show that the experiment removes the interfering homonuclear (1)H-(1)H, (13)C-(13)C and heteronuclear (1)H-(15)N, (13)C-(15)N dipolar interactions while retaining the desired heteronuclear (1)H-(13)C dipolar interaction. Our results indicate that this technique, combined with the numerical fitting, can be used to measure a (1)H-(13)C distance up to 5Å. We also demonstrate that the measured intramolecular (1)H-(13)C distances are useful to determine dihedral angles in proteins.

Triosephosphate isomerase: 15N and 13C chemical shift assignments and conformational change upon ligand binding by magic-angle spinning solid-state NMR spectroscopy.

Project description:Microcrystalline uniformly (13)C,(15)N-enriched yeast triosephosphate isomerase (TIM) is sequentially assigned by high-resolution solid-state NMR (SSNMR). Assignments are based on intraresidue and interresidue correlations, using dipolar polarization transfer methods, and guided by solution NMR assignments of the same protein. We obtained information on most of the active-site residues involved in chemistry, including some that were not reported in a previous solution NMR study, such as the side-chain carbons of His95. Chemical shift differences comparing the microcrystalline environment to the aqueous environment appear to be mainly due to crystal packing interactions. Site-specific perturbations of the enzyme's chemical shifts upon ligand binding are studied by SSNMR for the first time. These changes monitor proteinwide conformational adjustment upon ligand binding, including many of the sites probed by solution NMR and X-ray studies. Changes in Gln119, Ala163, and Gly210 were observed in our SSNMR studies, but were not reported in solution NMR studies (chicken or yeast). These studies identify a number of new sites with particularly clear markers for ligand binding, paving the way for future studies of triosephosphate isomerase dynamics and mechanism.

1H, 13C, and 15N chemical shift assignments of ZCCHC9.

Project description:ZCCHC9 is a human nuclear protein with sequence homology to yeast Air1p/Air2p proteins which are RNA-binding subunits of the Trf4/Air2/Mtr4 polyadenylation (TRAMP) complex involved in nuclear RNA quality control and degradation in yeast. The ZCCHC9 protein contains four retroviral-type zinc knuckle motifs. Here, we report the NMR spectral assignment of the zinc knuckle region of ZCCHC9. These data will allow performing NMR structural and RNA-binding studies of ZCCHC9 with the aim to investigate its role in the RNA quality control in human.

Gene expression in mouse retinas with cone cyclic nucleotide gated channel deficiencies

Project description:The cone photoreceptor cyclic nucleotide-gated (CNG) channel is essential for central and color vision and visual acuity. Mutations in the channel subunits CNGA3 and CNGB3 are associated with achromatopsia and cone dystrophy. We investigated the gene expression profiles in mouse retina with CNG channel deficiency on a cone-dominant background, i.e., CNGA3-/-/Nrl-/- and CNGB3-/-/Nrl-/- mice, relative to Nrl-/- mice. Total RNA was isolated from 2 retinas per animal (CNGA3-/-/Nrl-/-, CNGB3-/-/Nrl-/-, and Nrl-/- mice). The background strain for these mutations was C57bl/6.
