  • 1 H, 13 C, and 15 N resonance assignments for the tandem PHD finger motifs
           of human CHD4
    • Abstract: Abstract The plant homeodomain (PHD) zinc finger is a structural motif of about 40–60 amino acid residues found in many eukaryotic proteins that are involved in chromatin-mediated gene regulation. The human chromodomain helicase DNA binding protein 4 (CHD4) is a multi-domain protein that harbours, at its N-terminal end, a pair of PHD finger motifs (dPHD) connected by a ~30 amino acid linker. This tandem PHD motif is thought to be involved in targeting CHD4 to chromatin via its interaction with histone tails. Here we report the 1H, 13C and 15N backbone and side-chain resonance assignment of the entire dPHD by heteronuclear multidimensional NMR spectroscopy. These assignments provide the starting point for the determination of the structure, dynamics and histone-binding properties of this tandem domain pair.

  • Resonance assignment of the ligand-free cyclic nucleotide-binding domain
           from the murine ion channel HCN2
    • Abstract: Abstract Hyperpolarization activated and cyclic nucleotide-gated (HCN) ion channels as well as cyclic nucleotide-gated (CNG) ion channels are essential for the regulation of cardiac cells, neuronal excitability, and signaling in sensory cells. Both classes are composed of four subunits. Each subunit comprises a transmembrane region, intracellular N- and C-termini, and a C-terminal cyclic nucleotide-binding domain (CNBD). Binding of cyclic nucleotides to the CNBD promotes opening of both CNG and HCN channels. In case of CNG channels, binding of cyclic nucleotides to the CNBD is sufficient to open the channel. In contrast, HCN channels open upon membrane hyperpolarization and their activity is modulated by binding of cyclic nucleotides shifting the activation potential to more positive values. Although several high-resolution structures of CNBDs from HCN and CNG channels are available, the gating mechanism for murine HCN2 channel, which leads to the opening of the channel pore, is still poorly understood. As part of a structural investigation, here, we report the complete backbone and side chain resonance assignments of the murine HCN2 CNBD with part of the C-linker.

  • Solid-state NMR resonance assignments of the filament-forming CARD domain
           of the innate immunity signaling protein MAVS
    • Abstract: Abstract The mitochondrial antiviral signalling protein (MAVS) is a central signal transduction hub in the innate immune response against viral infections. Viral RNA present in the cytoplasm is detected by retinoic acid inducible gene I like receptors, which then activate MAVS via heterotypic interactions between their respective caspase activation and recruitment domains (CARD). This leads to the formation of active, high molecular weight MAVS complexes formed by homotypic interactions between the single N-terminal CARDs of MAVS. Filaments formed by the N-terminal MAVSCARD alone are sufficient to induce the autocatalytic conversion from a monomeric to an aggregated state in a prion-like manner. Here, we present the nearly complete spectroscopic 13C and 15N resonance assignments of human MAVSCARD filaments obtained from a single sample by magic angle spinning solid-state NMR spectroscopy. The corresponding secondary chemical shifts suggest that the filamentous form of MAVSCARD retains an exclusively alpha-helical fold that is very similar to the X-ray structure determined previously from monomeric MAVSCARD-maltose binding protein fusion constructs.

  • NMR study of non-structural proteins—part II: 1 H, 13 C, 15 N
           backbone and side-chain resonance assignment of macro domain from
           Venezuelan equine encephalitis virus (VEEV)
    • Abstract: Abstract Macro domains consist of 130–190 amino acid residues and appear to be highly conserved in all kingdoms of life. Intense research on this field has shown that macro domains bind ADP-ribose and other similar molecules, but their exact function still remains intangible. Macro domains are highly conserved in the Alphavirus genus and the Venezuelan equine encephalitis virus (VEEV) is a member of this genus that causes fatal encephalitis to equines and humans. In this study we report the high yield recombinant expression and preliminary solution NMR study of the macro domain of VEEV. An almost complete sequence-specific assignment of its 1H, 15N and 13C resonances was obtained and its secondary structure predicted by TALOS+. The protein shows a unique mixed α/β-fold.

  • Backbone 1 H, 13 C, and 15 N resonance assignments of the Fc fragment of
           human immunoglobulin G glycoprotein
    • Abstract: Abstract The Fc portion of immunoglobulin G (IgG) recruits complements and its cognate receptors, thereby promoting defensive mechanisms in the humoral immune system. These effector functions critically depend on N-glycosylation at the Fc region, which is therefore regarded as a crucial factor in the design and production of therapeutic antibodies. NMR spectroscopy plays a unique role in the characterization of conformational dynamics and intermolecular interactions of IgG-Fc in solutions. Here, we report NMR assignments of the glycosylated Fc fragment (Mr 53 kDa), cleaved from a chimeric antibody with human IgG1 constant regions, which was produced in Chinese hamster ovary cells with uniform 13C- and 15N-labeling.

  • Chemical shift assignments of DRB4 (1–153), a dsRNA binding protein
           in A. thaliana RNAi pathway
    • Abstract: Abstract RNA interference (RNAi) is a conserved biological response to dsRNA and regulates the expression of protein-coding genes to mediate resistance to both endogenous parasitic and exogenous pathogenic nucleic acids. In RNAi pathway, dsRNA binding proteins assists Dicer at various stages of RNAi. In plants, DRB4, is a multidomain protein containing two dsRNA binding domains that recognizes the long exogenous/endogenous dsRNA and presents it to Ribonuclease enzyme, Dicer like 4, resulting in the production of 21 nt small interfering RNA. Here, we report nearly complete backbone and sidechain chemical shift assignments of N-terminus of DRB4 (1–153, ~18 kDa), containing both double stranded RNA binding domains and the linker.

  • Backbone assignments of mini-RecA intein with short native exteins and an
           active N-terminal catalytic cysteine
    • Abstract: Abstract The backbone resonance assignments of an engineered splicing-inactive mini-RecA intein based on triple resonance experiments with [13C,15N]-labeled protein are reported. The construct contains inactivating mutations specifically designed to retain most catalytic residues, especially those that are potentially metal-coordinating. The assignments are essential for protein structure determination of a precursor with an active N-terminal catalytic cysteine and for investigation of the atomic details of splicing.

  • Backbone and side chain NMR assignment, along with the secondary structure
           prediction of RRM2 domain of La protein from a lower eukaryote exhibiting
           identical structural organization with its human homolog
    • Abstract: Abstract The La protein (Lupus antigen), a key mediator during biogenesis of RNA polymerase III transcripts, contains a characteristic La motif and one or two RNA recognition motif (RRM) domains, depending on the organism of origin. The RRM1 domain is conserved in higher eukaryotes and located in the N-terminal region, whereas the C-terminal RRM2 domain is absent in most lower eukaryotes and its specific role remains, so far, uncharacterized. Here, we present the backbone and side-chain assignment of the 1H, 13C and 15N resonances of RRM2 of La protein from Dictyostelium discoideum. Interestingly, the La protein in this lower eukaryote, exhibits high homology to its human counterpart. Moreover, it contains two RRM domains, instead of one, raising questions on its evolutionary origin and the putative role of RRM2 in vivo. We also provide its secondary structure as predicted by the TALOS+ online tool.

It contains a central RNA binding domain and a predicted C-terminal coiled-coil domain. Here we report the almost complete (>90 %) 1H,13C,15N backbone and side chain NMR assignment of a 15 kDa Nop6 construct comprising the RNA binding and coiled-coil domains.

  • Resonance assignments of the microtubule-binding domain of the        class="a-plus-plus">C. elegans spindle and
           kinetochore-associated protein 1
    • Abstract: Abstract During mitosis, kinetochores coordinate the attachment of centromeric DNA to the dynamic plus ends of microtubules, which is hypothesized to pull sister chromatids toward opposing poles of the mitotic spindle. The outer kinetochore Ndc80 complex acts synergistically with the Ska (spindle and kinetochore-associated) complex to harness the energy of depolymerizing microtubules and power chromosome movement. The Ska complex is a hexamer consisting of two copies of the proteins Ska1, Ska2 and Ska3, respectively. The C-terminal domain of the spindle and kinetochore-associated protein 1 (Ska1) is the microtubule-binding domain of the Ska complex. We solved the solution structure of the C. elegans microtubule-binding domain (MTBD) of the protein Ska1 using NMR spectroscopy. Here, we report the resonance assignments of the MTBD of C. elegans Ska1.

  • NMR assignments of a hypothetical pseudo-knotted protein HP0242 from
           Helicobacter pylori
    • Abstract: Abstract Many knotted proteins have been discovered recently, but the folding process of which remains elusive. HP0242 is a hypothetical protein from Helicobacter pylori, which is a model system for studying the folding pathway of a knotted protein. In this study, we report the 1H, 13C, and 15N chemical shift assignments of HP0242. The results will enable us to further investigate HP0242 by NMR experiments.

           assignment of murine interleukin-10
    • Abstract: Abstract Almost complete assignment of backbone 1H, 13C, 15N and side chain 13Cβ resonances for the immune-regulatory cytokine IL-10 is reported. The protein was overexpressed in Escherichia coli and was refolded from inclusion bodies. The point mutation C149Y was introduced to suppress incorrect disulfide bond formation and to improve protein refolding.

  • Yet another polymorph of α-synuclein: solid-state sequential
    • Abstract: Abstract Parkinson’s disease is a neurological human proteinopathy, which is caused by the accumulation of protein aggregates of high molecular mass. α-Synuclein is a major component of these fibrillar, β-sheet rich, insoluble assemblies and is deposited in the form of amyloids. Structural characterization of amyloids is possible by solid-state NMR, although no atomic-resolution structure is available as of today. α-Synuclein, as many other pathology-related fibril-forming proteins, can form a number of different polymorphs that are sometimes tricky to obtain in pure form. Here, we describe the chemical shifts and secondary structure analysis of a polymorph that also adopts mainly β-sheet conformation, with a fibrillar core ranging from residues 38 to 94. In addition, residues 15–20 from the N-terminus found to be part of a rigid ordered β-sheet. The chemical shifts differ substantially from the polymorph we previously assigned.

  • 1H,        class="a-plus-plus">13C and        class="a-plus-plus">15N backbone and side-chain
           resonance assignments of a family 36 carbohydrate binding module of
           xylanase from Paenibacillus
    • Abstract: Abstract Paenibacillus campinasensis BL11 isolated from black liquor secretes multiple glycoside hydrolases (GHs) against all kinds of polysaccharides. GH consists of a catalytic module and non-catalytic carbohydrate-binding modules (CBMs), in which CBMs append to the catalytic module, mediating specific interactions with insoluble carbohydrates to promote the hydrolysis efficiency of the cognate enzyme. Endo-β-1,4-xylanase (XylX) is one of the GHs reveals high enzymatic activity in a wide range of pH and thermal endurance, suitable for bioconversion and bio-refinement applications. In this work, we report the resonance assignments of a family 36 CBM (characterized as CBM36) derived from XylX. Our investigations will facilitate molecular structure determination and molecular dynamics analysis of CBMs.

           the OB domain of the single stranded DNA binding protein from        class="a-plus-plus">Sulfolobus solfataricus and
           chemical shift mapping of the DNA-binding interface
    • Abstract: Abstract Single stranded DNA binding proteins (SSBs) are present in all known cellular organisms and are critical for DNA replication, recombination and repair. The SSB from the hyperthermophilic crenarchaeote Sulfolobus solfataricus (SsoSSB) has an unusual domain structure with a single DNA-binding oligonucleotide binding (OB) fold coupled to a flexible C-terminal tail. This ‘simple’ domain organisation differs significantly from other known SSBs, such as human replication protein A (RPA). However, it is conserved in another important human SSB, hSSB1, which we have recently discovered and shown to be essential in the DNA damage response. In this study we report the solution-state backbone and side-chain chemical shift assignments of the OB domain of SsoSSB. In addition, using the recently determined crystal structure, we have utilized NMR to reveal the DNA-binding interface of SsoSSB. These data will allow us to elucidate the structural basis of DNA-binding and shed light onto the molecular mechanism by which these ‘simple’ SSBs interact with single-stranded DNA.

  • Backbone resonance assignments of the 42 kDa enzyme arginine kinase
           in the transition state analogue form
    • Abstract: Abstract Nearly complete backbone resonance assignments for the 357 residue, 42 kDa enzyme arginine kinase in a transition state analogue (TSA) complex are presented. The TSA is a quaternary complex of arginine kinase, MgADP, arginine, and nitrate. About 93 % (320 of 344) of the non-proline backbone amides were assigned using an enzyme enriched with 2H, 13C, and 15N in combination with three enzyme samples prepared with a single 15N-labeled amino acid (K, L, and R). The amide assignments will provide the foundation for investigating the dynamics of arginine kinase when in a TSA complex.

  • Backbone resonance assignments of human cytosolic dNT-1 nucleotidase
    • Abstract: Abstract Cytosolic dNT-1 nucleotidase plays a key role in the homeostasis of pyrimidine deoxyribonucleotides in mammalian cells. The enzyme is responsible for the dephosphorylation of physiological substrates as well as nucleoside analogues that are used in antiviral and anticancer therapies, therefore selective inhibition of the dNT-1 nucleotidase activity may lead to an increase in efficacy of this type of therapeutic compounds. Here, we report the backbone 1H, 13C and 15N assignments for the 47 kDa dNT-1 dimer, which will be used for structural characterisation of dNT-1 complexes with small molecule inhibitors obtained through modification of pyrimidine nucleotide scaffolds or optimisation of successful binders obtained from the screening of fragment libraries.

  • Chemical shift assignments of a reduced N-terminal truncation mutant of
           the disulfide bond isomerase TrbB from plasmid F, TrbBΔ29
    • Abstract: Abstract TrbB from the conjugative plasmid F is a 181-residue disulfide bond isomerase that plays a role in the correct folding and maintenance of disulfide bonds within F plasmid encoded proteins in the bacterial periplasm. As a member of the thioredoxin-like superfamily, TrbB has a predicted thioredoxin-like fold that contains a C–X–X–C active site required for performing specific redox chemistries on protein substrates. Here we report the sequence-specific assignments of the reduced form of the N-terminally truncated TrbB construct, TrbBΔ29.
