  • Backbone and ILV side-chain NMR resonance assignments of the catalytic
           domain of human deubiquitinating enzyme USP7

    • Free pre-print version: Loading...

      Abstract: Abstract Ubiquitin specific protease 7 (USP7) is a deubiquitinating enzyme, which removes ubiquitin tag from numerous protein substrates involved in diverse cellular processes such as cell cycle regulation, apoptosis and DNA damage response. USP7 affects stability, interaction network and cellular localization of its cellular and viral substrates by controlling their ubiquitination status. The large 41 kDa catalytic domain of USP7 harbors the active site of the enzyme. Here we present a nearly complete (93%) NMR resonance assignment of isoleucine, leucine and valine (ILV) side-chains of the USP7 catalytic domain along with a refined nearly complete (93%) assignment of its backbone resonances. The reported ILV methyl group assignment will facilitate further NMR investigations of structure, interactions and conformational dynamics of the USP7 enzyme.

  • Secondary structure and 1H, 15 N & 13C resonance assignments of the
           periplasmic domain of OutG, major pseudopilin from Dickeya dadantii type
           II secretion system

    • Free pre-print version: Loading...

      Abstract: Abstract The ability to interact and adapt to the surrounding environment is vital for bacteria that colonise various niches and organisms. One strategy developed by Gram-negative bacteria is to secrete exoprotein substrates via the type II secretion system (T2SS). The T2SS is a proteinaceous complex spanning the bacterial envelope that translocates folded proteins such as toxins and enzymes from the periplasm to the extracellular milieu. In the T2SS, a cytoplasmic ATPase elongates in the periplasm the pseudopilus, a non-covalent polymer composed of protein subunits named pseudopilins, and anchored in the inner membrane by a transmembrane helix. The pseudopilus polymerisation is coupled to the secretion of substrates. The T2SS of Dickeya dadantii secretes more than 15 substrates, essentially plant cell wall degrading enzymes. In D. dadantii, the major pseudopilin or the major subunit of the pseudopilus is called OutG. To better understand the mechanism of secretion of these numerous substrates via the pseudopilus, we have been studying the structure of OutG by NMR. Here, as the first part of this study, we report the 1H, 15N and 13C backbone and sidechain chemical shift assignment of the periplasmic domain of OutG and its NMR derived secondary structure.

      Abstract: Abstract The dysbindin domain-containing protein 1 (DBNDD1) is a conserved protein among higher eukaryotes whose structure and function are poorly investigated so far. Here, we present the backbone and side chain nuclear magnetic resonance assignments for the human DBNDD1 protein. Our chemical-shift based secondary structure analysis reveals the human DBNDD1 as an intrinsically disordered protein.

  • Chemical shift assignments of calmodulin under standard conditions at
           neutral pH

    • Free pre-print version: Loading...

      Abstract: Abstract The Ca2+ sensor protein, calmodulin (CaM) is ubiquitously expressed in all cells where it binds to hundreds of different target proteins, including dozens of enzymes, receptors, ion channels and numerous Ca2+ transporters. The only published NMR chemical shift assignments for Ca2+-bound CaM (in the absence of a target) have been determined under acidic conditions: at pH 6.5/310 K (BMRB 6541) and pH 6.3/320 K (BMRB 547). However, some CaM/target complexes are not soluble under these conditions. Also, amide chemical shifts are very sensitive to pH and temperature, which can cause large baseline errors when using the existing chemical shift assignments of free CaM to calculate chemical shift perturbations caused by target binding at neutral pH and physiological temperature. We report complete NMR chemical shift assignments of Ca2+-saturated CaM under a set of standard conditions at neutral pH and 308 K that will enable more accurate chemical shift comparison between free CaM and CaM/target complexes (BMRB 51289).

  • 1 H, 15 N and 13 C chemical shift assignments of the N-terminal domain
           of the two isoforms of the human apolipoprotein E

    • Free pre-print version: Loading...

      Abstract: Abstract Apolipoprotein E (ApoE) is one of the major lipid transporters in humans. It is also implicated in pathological conditions like Alzheimer’s and cardiovascular diseases. The N-terminal domain of ApoE binds low-density lipoprotein receptors (LDLR) while the C-terminal domain binds to the lipid. I report the backbone and aliphatic side-chain NMR chemical shifts of the N-terminal domain of two isoforms of ApoE, namely ApoE3 NTD (BMRB No. 51,122) and ApoE4 NTD (BMRB No. 51,123) at pH 3.5 (20 °C).

  • Backbone NMR assignments of the extensive human and chicken TRPV4
           N-terminal intrinsically disordered regions as important players in ion
           channel regulation

    • Free pre-print version: Loading...

      Abstract: Abstract Transient receptor potential (TRP) channels are important pharmacological targets due to their ability to act as sensory transducers on the organismic and cellular level, as polymodal signal integrators and because of their role in numerous diseases. However, a detailed molecular understanding of the structural dynamics of TRP channels and their integration into larger cellular signalling networks remains challenging, in part due to the systematic absence of highly dynamic regions pivotal for channel regulation from available structures. In human TRP vanilloid 4 (TRPV4), a ubiquitously expressed homotetrameric cation channel involved in temperature, osmo- and mechano-sensation and in a multitude of (patho)physiological processes, the intrinsically disordered N-terminus encompasses 150 amino acids and thus represents > 17% of the entire channel sequence. Its deletion renders the channel significantly less excitable to agonists supporting a crucial role in TRPV4 activation and regulation. For a structural understanding and a comparison of its properties across species, we determined the NMR backbone assignments of the human and chicken TRPV4 N-terminal IDRs.

  • Solid state NMR chemical shift assignment of the non-structural
           single-stranded DNA binding protein gVp from fd bacteriophage

    • Free pre-print version: Loading...

      Abstract: Abstract The non-structural gene V protein (pV, gVp) from fd virus is a non-specific single-stranded DNA binding protein. The role of gVp is to sequester the single-stranded DNA thus reducing the generation of the replicative DNA form and leading to the formation of progeny phage. In this study, we assigned the 13C and 15N resonances of the crystalline unbound protein by magic-angle spinning solid-state NMR. The secondary structure predicted by the NMR shifts is in excellent agreement with the X-ray structure of the same 87-residue protein.

  • 1H, 13C and 15N chemical shift assignments of the ZnR and GYF cytoplasmic
           domains of the GltJ protein from Myxococcus xanthus

    • Free pre-print version: Loading...

      Abstract: Abstract Bacterial cell motility is essential for a range of physiological phenomena such as nutrient sensing, predation, biofilm formation and pathogenesis. One of the most intriguing motilities is bacterial gliding, which is defined as the ability of some bacteria to move across surfaces without an external appendage. In Myxococcus xanthus, gliding motility depends on the assembly of focal adhesion complexes (FAC) which include the Glt mutiprotein complex and allow directional movement of individual cells (A-motility). Within the Glt multiprotein complex, GltJ is one of the key proteins involved in FAC assembly. In this work we report complete backbone and side chain 1H, 13C and 15N chemical shifts of the two cytoplasmic domains of GltJ, GltJ-ZnR (BMRB No. 51104) and GltJ-GYF (BMRB No. 51096). These data provide the first step toward the first high resolution structures of protein domains from the Glt machinery and the atomic level characterization of GltJ cytoplasmic activity during FAC assembly.

           synthase/prostaglandin J2 complex

    • Free pre-print version: Loading...

      Abstract: Abstract Lipocalin-type prostaglandin (PG) D synthase (L-PGDS) catalyzes the isomerization of PGH2 to produce PGD2, an endogenous somenogen, in the brains of various mammalians. We recently reported that various other PGs also bind to L-PGDS, suggesting that it could serve as an extracellular carrier for PGs. Although the solution and crystal structure of L-PGDS has been determined, as has the structure of L-PGDS complexed PGH2 analog, a structural analysis of L-PGDS complexed with other PGs is needed in order to understand the mechanism responsible for the PG trapping. Here, we report the nearly complete 1H, 13C, and 15N backbone and side chain resonance assignments of the L-PGDS/PGJ2 complex and the binding site for PGJ2 on L-PGDS.

      Abstract: Abstract Phafin2 is a peripheral protein that triggers cellular signaling from endosomal and lysosomal compartments. The specific subcellular localization of Phafin2 is mediated by the presence of a tandem of phosphatidylinositol 3-phosphate (PtdIns3P)-binding domains, the pleckstrin homology (PH) and the Fab-1, YOTB, Vac1, and EEA1 (FYVE) domains. The requirement for both domains for binding to PtdIns3P still remains unclear. To understand the molecular interactions of the Phafin2 PH domain in detail, we report its nearly complete 1H, 15N, and 13C backbone resonance assignments.

           domain of SARS-CoV-2 non-structural protein 3

    • Free pre-print version: Loading...

      Abstract: Abstract The worldwide COVID-19 pandemic is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Nonstructural protein 3 (nsp3) has 1945 residues and is the largest protein encoded by SARS-CoV-2. It comprises more than a dozen independent domains with various functions. Many of these domains were studied in the closely-related virus SARS-CoV following an earlier outbreak. Nonetheless structural and functional information on the C-terminal region of nsp3 containing two transmembrane and three extra-membrane domains remains incomplete. This part of the protein appears to be involved in initiation of double membrane vesicle (DMV) formation, membranous organelles the virus builds to hide its replication-transcription complex from host immune defenses. Here we present the near-complete backbone and Ile, Leu, and Val methyl group chemical shift assignments of the most C-terminal domain of nsp3, CoV-Y. As the exact function and binding partners of CoV-Y remain unknown, our data provide a basis for future NMR studies of protein–protein interactions to elucidate the molecular mechanism of DMV formation.

  • 1H, 13C and 15N resonance assignments of the first BIR domain of cellular
           inhibitor of apoptosis protein 1

    • Free pre-print version: Loading...

      Abstract: Abstract Cellular inhibitor of apoptosis protein-1 (cIAP-1) is member of inhibitor of apoptosis proteins (IAPs) which can affect apoptosis through interactions with caspases. cIAP-1 is a multi-domain protein and able to regulate apoptosis through interactions with proteins such as caspases and possesses E3 ligase activity. Human cIAP-1 contains three baculovirus IAP repeat (BIR) domains which are critical for protein–protein interactions. Here, we report NMR resonance assignments of the first BIR domain of human cIAP. Its secondary structures in solution were determined based on the assigned resonances. The dynamics of this domain was obtained, and our hydrogen–deuterium exchange experiment reveals that the first helix in BIR1 is exposed to the solvent. The availability of assignments of backbone and side chain resonances will be useful for probing protein–protein interactions.

           tobacco calmodulin 2

    • Free pre-print version: Loading...

      Abstract: Abstract Calcium is a ubiquitous second messenger regulating numbers of cellular processes in living organisms. It encodes and transmits information perceived by cells to downstream sensors, including calmodulin (CaM), that initiate cellular responses. In plants, CaM has been involved in the regulation of plant responses to biotic and abiotic environmental cues. Plant CaMs possess a cysteine residue in their first calcium-binding motif EF-hand, which is not conserved in other eucaryotic organisms. In this work, we report the near-complete backbone chemical shift assignment of tobacco CaM2 with calcium. These results will be useful to study the impact of this particular EF-hand domain regarding CaM interaction with partners involved in stress responses.

  • Backbone NMR assignment of the nucleotide binding domain of the Bacillus
           subtilis ABC multidrug transporter BmrA in the post-hydrolysis state

    • Free pre-print version: Loading...

      Abstract: Abstract ATP binding cassette (ABC) proteins are present in all phyla of life and form one of the largest protein families. The Bacillus subtilis ABC transporter BmrA is a functional homodimer that can extrude many different harmful compounds out of the cell. Each BmrA monomer is composed of a transmembrane domain (TMD) and a nucleotide binding domain (NBD). While the TMDs of ABC transporters are sequentially diverse, the highly conserved NBDs harbor distinctive conserved motifs that enable nucleotide binding and hydrolysis, interdomain communication and that mark a protein as a member of the ABC superfamily. In the catalytic cycle of an ABC transporter, the NBDs function as the molecular motor that fuels substrate translocation across the membrane via the TMDs and are thus pivotal for the entire transport process. For a better understanding of the structural and dynamic consequences of nucleotide interactions within the NBD at atomic resolution, we determined the 1H, 13C and 15N backbone chemical shift assignments of the 259 amino acid wildtype BmrA-NBD in its post-hydrolytic, ADP-bound state.

  • Assignment of Ala, Ile, LeuproS, Met, and ValproS methyl groups of the
           protruding domain of murine norovirus capsid protein VP1 using
           

    • Free pre-print version: Loading...

      Abstract: Abstract The protruding domain (P-domain) of the murine norovirus (MNV) capsid protein VP1 is essential for infection. It mediates receptor binding and attachment of neutralizing antibodies. Protein NMR studies into interactions of the P-domain with ligands will yield insights not easily available from other biophysical techniques and will extend our understanding of MNV attachment to host cells. Such studies require at least partial NMR assignments. Here, we describe the assignment of about 70% of the Ala, Ile, LeuproS, Met, and ValproS methyl groups. An unfavorable distribution of methyl group resonance signals prevents complete assignment based exclusively on 4D HMQC-NOESY-HMQC experiments, yielding assignment of only 55 out of 100 methyl groups. Therefore, we created point mutants and measured pseudo contact shifts, extending and validating assignments based on methyl-methyl NOEs. Of note, the P-domains are present in two different forms caused by an approximate equal distribution of trans- and cis-configured proline residues in position 361.

      Abstract: Abstract Members of the tristetraprolin (TTP) family of RNA binding proteins (RBPs) regulate the metabolism of a variety of mRNA targets. In mammals, these proteins modulate many physiological processes, including immune cell activation, hematopoiesis, and embryonic development. Regulation of mRNA stability by these proteins requires that the tandem zinc finger (TZF) domain binds initially and directly to target mRNAs, ultimately leading to their deadenylation and decay. Proteins of this type throughout eukarya possess a highly conserved TZF domain, suggesting that they are all capable of high-affinity RNA binding. However, the mechanism of TTP-mediated mRNA decay is largely undefined. Given the vital role that these TTP family proteins play in maintaining RNA homeostasis throughout eukaryotes, we focused here on the first, key step in this process: recognition and binding of the TZF domain to target RNA. For these studies, we chose a primitive plant, the spikemoss Selaginella moellendorffii, which last shared a common ancestor with humans more than a billion years ago. Here we report the near complete backbone and side chain resonance assignments of the spikemoss TZF domain, including: (1) the assignment of the RNA-TZF domain complex, representing one of only two data sets currently available for the entire TTP family of proteins; and (2) the first NMR resonance assignments of the entire TZF domain, in the RNA-free form. This work will serve as the basis for further NMR structural investigations aimed at gaining insights into the process of RNA recognition and the mechanisms of TTP-mediated mRNA decay.

  • Chemical shift assignments of calmodulin bound to the β-subunit of a
           retinal cyclic nucleotide-gated channel (CNGB1)

    • Free pre-print version: Loading...

      Abstract: Abstract Rod cyclic nucleotide-gated (CNG) channels are formed by two protein subunits (CNGA1 and CNGB1). Calmodulin (CaM) binds to the cytosolic regulatory domain of CNGB1 and decreases the open probability of CNGA1/CNGB1 channels. The CaM binding site within bovine CNGB1 (residues 679–702) binds tightly to Ca2+-bound CaM, which promotes Ca2+-induced inactivation of CNGA1/CNGB1 channels in retinal rods. We report complete NMR chemical shift assignments of Ca2+-saturated CaM bound to the CaM-binding domain of CNGB1 (BMRB no. 51222).

  • 1H, 13C and 15N resonance assignments of TFIIS LW domain from
           Saccharomyces cerevisiae

    • Free pre-print version: Loading...

      Abstract: Abstract TFIIS is one of the best-characterized transcription elongation factors, with a domain I (named also as LW domain) in the N-terminus. It can relieve the arrest of RNA polymerase II (RNAP II) when the elongation of RNAP II is impaired. Here we report the resonance assignments of the protein backbone and side chains of the LW domain of TFIIS from S. cerevisiae, the secondary structure prediction indicates the ScTFIIS LW domain contains six α-helices with no β-sheet, which will lay the foundation for the protein structure determination and function elucidation.
