  • 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.

  • Yet another polymorph of α-synuclein: solid-state sequential
           assignments
    • 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
           campinasensis
    • 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 the C-terminal Eps15 homology domain-3 EH
           domain
    • Abstract: Abstract The C-terminal Eps15 homology (EH) domain 3 (EHD3) belongs to a eukaryotic family of endocytic regulatory proteins and is involved in the recycling of various receptors from the early endosome to the endocytic recycling compartment or in retrograde transport from the endosomes to the Golgi. EH domains are highly conserved in the EHD family and function as protein-protein interaction units that bind to Asn-Pro-Phe (NPF) motif-containing proteins. The EH domain of EHD1 was the first C-terminal EH domain from the EHD family to be solved by NMR. The differences observed between this domain and proteins with N-terminal EH domains helped describe a mechanism for the differential binding of NPF-containing proteins. Here, structural studies were expanded to include the EHD3 EH domain. While the EHD1 and EHD3 EH domains are highly homologous, they have different protein partners. A comparison of these structures will help determine the selectivity in protein binding between the EHD family members and lead to a better understanding of their unique roles in endocytic regulation.

  • Backbone and side-chain assignments of an effector membrane localization
           domain from Vibrio
           vulnificus
    MARTX toxin
    • Abstract: Abstract 1H, 13C, and 15N chemical shift assignments are presented for the isolated four-helical bundle membrane localization domain from the domain of unknown function 5 (DUF5) effector (MLDVvDUF5) of the MARTX toxin from Vibrio vulnificus in its solution state. We have assigned 97 % of all backbone and side-chain carbon atoms, including 96 % of all backbone residues. Secondary chemical shift analysis using TALOS+ demonstrates four helices that align with those predicted by structure homology modeling using the MLDs of Pasteurella multocida toxin (PMT) and the clostridial TcdB and TcsL toxins as templates. Future studies will be towards solving the structure and determining the dynamics in the solution state.

    • Abstract: Abstract The Hedgehog (Hh) signaling pathway plays important roles in embryonic growth and patterning in different organisms. Abnormal activity of the Hh signaling pathway has been associated to cancers, holoprosencephaly and autism spectrum disorders. The backbone and side chain resonance assignments of a Drosophila Hh autoprocessing domain have been determined based on triple-resonance experiments with the [13C, 15N]-labeled and [2H, 13C, 15N])-labeled proteins.

  • 13C,        class="a-plus-plus">15N and        class="a-plus-plus">1H backbone and side chain
           
    • Abstract: Abstract HdeA is a small chaperone found in the periplasm of several common pathogenic bacteria (Escherichia coli, Shigella flexneri and Brucella abortus) which are the leading causes of dysentery worldwide, especially in developing countries. Its job is to protect other periplasmic proteins from aggregating as the bacteria pass through the low pH environment of the human stomach on their way to infect the intestines. HdeA is an inactive folded dimer at neutral pH, but becomes a disordered active monomer at pH < 3. To initiate NMR characterization of HdeA at pH 6, 94 % of the backbone and 86 % of the side chain chemical shifts have been assigned. The loop linking helices B and C remains largely unassigned due to missing peaks in the 1H–15N HSQC and other spectra, most likely due to intermediate timescale chemical exchange. Many of the weakest intensity backbone peaks correspond to residues that surround this loop within the tertiary structure. Assignment experiments have therefore helped to provide preliminary clues about the region of the protein that may be most responsible for initiating unfolding as the pH drops, and constitute an important first step in improving our understanding of, and ultimately combatting, HdeA activity.

  • 1H,        class="a-plus-plus">13C and        class="a-plus-plus">15N backbone and side-chain
           resonance assignments of the N-terminal ubiquitin-binding domains of USP25
           
    • Abstract: Abstract Ubiquitin Specific Protease 25 (USP25), a member of the deubiquitinase family, is involved in several disease-related signal pathways including myogenesis, immunity and protein degradation. It specially catalyzes the hydrolysis of the K48-linked and K63-linked polyubiquitin chains. USP25 contains one ubiquitin-associated domain and two ubiquitin-interacting motifs (UIMs) in its N-terminal region, which interact with ubiquitin and play a role in substrate recognition. Besides, it has been shown that the catalysis activity of USP25 is either impaired by sumoylation or enhanced by ubiquitination within its UIM. To elucidate the structural basis of the cross-regulation of USP25 function by non-covalent binding and covalent modifications of ubiquitin and SUMO2/3, a systematic structural biology study of USP25 is required. Here, we report the 1H, 13C and 15N backbone and side-chain resonance assignments of the N-terminal ubiquitin binding domains (UBDs) of USP25 with BMRB accession number of 19111, which is the first step of the systematic structural biology study of the enzyme.

  • Solid-state NMR sequential assignments of the amyloid core of full-length
           Sup35p
    • Abstract: Abstract Sup35p is a yeast prion and is responsible for the [PSI +] trait in Saccharomyces cerevisiae. With 685 amino acids, full-length soluble and fibrillar Sup35p are challenging targets for structural biology as they cannot be investigated by X-ray crystallography or NMR in solution. We present solid-state NMR studies of fibrils formed by the full-length Sup35 protein. We detect an ordered and rigid core of the protein that gives rise to narrow and strong peaks, while large parts of the protein show either static disorder or dynamics on time scales which interfere with dipolar polarization transfer or shorten the coherence lifetime. Thus, only a small subset of resonances is observed in 3D spectra. Here we describe in detail the sequential assignments of the 22 residues for which resonances are observed in 3D spectra: their chemical shifts mostly corresponding to β-sheet secondary structure. We suspect that these residues form the amyloid core of the fibril.

  • NMR assignments of PI3-SH3 domain aided by protonless NMR spectroscopy
    • Abstract: Abstract We report here the near complete assignments of native bovine PI3-SH3 domain, which has been a model system for protein folding, misfolding and amyloid fibril formation. The use of 13C-detected protonless NMR spectroscopy is instrumental in assigning the spin system of the proline residue at the C-terminus in addition to the missing resonances in proton-based NMR spectra due to rapid solvent exchange. It also helps assign the resonances of all three proline amine nitrogen nuclei, which are underrepresented in the database. Comparison of the backbone 13C resonances of PI3-SH3 in its native and amyloid fibril states shows that the aggregation of PI3-SH3 is accompanied by major conformational rearrangements.

  • 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.
