  • Backbone 1 H, 15 N, and 13 C resonance assignments of the Tom1 VHS domain
    • Authors: Jeffrey F. Ellena; Wen Xiong; Xiaolin Zhao; Narasimhamurthy Shanaiah; Daniel G. S. Capelluto
      Pages: 1 - 4
      Abstract: Efficient trafficking of ubiquitinated receptors (cargo) to endosomes requires the recruitment of adaptor proteins that exhibit ubiquitin-binding domains for recognition and transport. Tom1 is an adaptor protein that not only associates with ubiquitinated cargo but also represents a phosphoinositide effector during specific bacterial infections. This phosphoinositide-binding property is associated with its N-terminal Vps27, Hrs, STAM (VHS) domain. Despite its biological relevance, there are no resonance assignments of Tom1 VHS available that can fully characterize its molecular interactions. Here, we report the nearly complete 1H, 15N, and 13C backbone resonance assignments of the VHS domain of human Tom1.

  • 1 H, 15 N and 13 C resonance assignments for free and IEEVD peptide-bound
           forms of the tetratricopeptide repeat domain from the human E3 ubiquitin
           ligase CHIP
    • Authors: Huaqun Zhang; Cameron McGlone; Matthew M. Mannion; Richard C. Page
      Pages: 5 - 9
      Abstract: The ubiquitin ligase CHIP catalyzes covalent attachment of ubiquitin to unfolded proteins chaperoned by the heat shock proteins Hsp70/Hsc70 and Hsp90. CHIP interacts with Hsp70/Hsc70 and Hsp90 by binding of a C-terminal IEEVD motif found in Hsp70/Hsc70 and Hsp90 to the tetratricopeptide repeat (TPR) domain of CHIP. Although recruitment of heat shock proteins to CHIP via interaction with the CHIP-TPR domain is well established, alterations in structure and dynamics of CHIP upon binding are not well understood. In particular, the absence of a structure for CHIP-TPR in the free form presents a significant limitation upon studies seeking to rationally design inhibitors that may disrupt interactions between CHIP and heat shock proteins. Here we report the 1H, 13C, and 15N backbone and side chain chemical shift assignments for CHIP-TPR in the free form, and backbone chemical shift assignments for CHIP-TPR in the IEEVD-bound form. The NMR resonance assignments will enable further studies examining the roles of dynamics and structure in regulating interactions between CHIP and the heat shock proteins Hsp70/Hsc70 and Hsp90.

  • NMR assignments of the GacS histidine-kinase periplasmic detection domain
           from Pseudomonas aeruginosa PAO1
    • Authors: Ahmad Ali-Ahmad; Olivier Bornet; Firas Fadel; Yves Bourne; Florence Vincent; Christophe Bordi; Françoise Guerlesquin; Corinne Sebban-Kreuzer
      Pages: 25 - 28
      Abstract: Pseudomonas aeruginosa is a highly adaptable opportunistic pathogen. It can infect vulnerable patients such as those with cystic fibrosis or hospitalized in intensive care units where it is responsible for both acute and chronic infection. The switch between these infections is controlled by a complex regulatory system involving the central GacS/GacA two-component system that activates the production of two small non-coding RNAs. GacS is a histidine kinase harboring one periplasmic detection domain, two inner-membrane helices and three H1/D1/H2 cytoplasmic domains. By detecting a yet unknown signal, the GacS histidine-kinase periplasmic detection domain (GacSp) is predicted to play a key role in activating the GacS/GacA pathway. Here, we present the chemical shift assignment of 96 % of backbone atoms (HN, N, C, Cα, Cβ and Hα), 88 % aliphatic hydrogen atoms and 90 % of aliphatic carbon atoms of this domain. The NMR-chemical shift data, on the basis of Talos server secondary structure predictions, reveal that GacSp consists of 3 β-strands, 3 α-helices and a major loop devoid of secondary structures.

  • 1 H, 13 C and 15 N NMR assignments of a bacterial immunoglobulin-like
           domain (group 2) of a protein of a bacterium Paenarthrobacter aurescens
           TC1
    • Authors: Asmita D. Pawar; Deepshikha Verma; Rajeev Raman; Yogendra Sharma; Kandala V. R. Chary
      Abstract: The bacterial immunoglobulin-like (Big) domain is one of the prevalent domain types, which facilitates cell–cell adhesion by assembling into multi-domain architectures. We selected a four Big_2 domain protein (named ‘Arig’) from a Gram positive, Paenarthrobacter aurescens TC1 (known earlier as Arthrobacter aurescens TC1). In an attempt to characterize structural and ligand-binding features of individual Big_2 domains, we have cloned, overexpressed, isolated and purified the second Big_2 domain of Arig along with a few of its adjacent Big_2 domain residues (residue 143 to 269) referred to as ‘Arig2’. The 13C/15N-doubly-labeled His-tagged Arig2 (133 residues long) showed an ordered conformation as revealed by the well dispersed 2D [15N-1H]-HSQC spectrum. Subsequently, a suite of heteronuclear 3D NMR experiments has enabled almost complete 1H, 13C and 15N NMR resonance assignments of Arig2.

  • 1 H, 13 C and 15 N NMR chemical shift assignments of A. thaliana RCD1 RST
    • Authors: Helena Tossavainen; Maarit Hellman; Julia P. Vainonen; Jaakko Kangasjärvi; Perttu Permi
      Abstract: The A. thaliana RCD1 (radical-induced cell death1) protein is a cellular signaling hub protein which interacts with numerous plant transcription factors from different families. It consists of three conserved domains and intervening unstructured regions, the C-terminal RST domain being responsible for the interactions with the transcription factors. It has been shown that many partner proteins interact with RCD1 RST via their intrinsically disordered regions, and that the domain is able to house partners with divergent folds. We aim to structurally characterize the RCD1 RST domain and its complexes [complex with DREB2A]. Here we report the 1H, 15N and 13C chemical shift assignments of the backbone and sidechain atoms for RCD1 (468–589) containing the RST (510–567) domain.

  • 1 H, 13 C, and 15 N backbone chemical shift assignments of 4E-BP1 44–87
           and 4E-BP1 44–87 bound to eIF4E
    • Authors: Naotaka Sekiyama; Andras Boeszoermenyi; Haribabu Arthanari; Gerhard Wagner; Mélissa Léger-Abraham
      Abstract: The eukaryotic translational initiation factor 4G (eIF4G) interacts with the cap-binding protein eIF4E through a consensus binding motif, Y(X)4LΦ (where X is any amino acid and Φ is a hydrophobic residue). 4E binding proteins (4E-BPs), which also contain a Y(X)4LΦ motif, regulate the eIF4E/eIF4G interaction. The non- or minimally-phosphorylated form of 4E-BP1 binds eIF4E, preventing eIF4E from interacting with eIF4G, thus inhibiting translation initiation. 4EGI-1, a small molecule inhibitor of the eIF4E/eIF4G interaction that is under investigation as a novel anti-cancer drug, has a dual activity; it disrupts the eIF4E/eIF4G interaction and stabilizes the binding of 4E-BP1 to eIF4E. Here, we report the complete backbone NMR resonance assignment of an unliganded 4E-BP1 fragment (4E-BP144–87). We also report the near complete backbone assignment of the same fragment in complex to eIF4E/m7GTP (excluding the assignment of the last C-terminus residue, D87). The chemical shift data constitute a prerequisite to understanding the mechanism of action of translation initiation inhibitors, including 4EGI-1, that modulate the eIF4E/4E-BP1 interaction.

  • H N , N, C α and C β assignments of the two periplasmic domains of
           Neisseria meningitidis DsbD
    • Authors: Roxanne P. Smith; Biswaranjan Mohanty; Martin L. Williams; Martin J. Scanlon; Begoña Heras
      Abstract: DsbD is a disulfide bond reductase present in the inner membrane of many Gamma-Proteobacteria. In the human pathogen Neisseria meningitidis, DsbD is required for viability and represents a potential target for the development of antibiotics. Here we report the chemical shift assignments (HN, N, Cα and Cβ) for the reduced and oxidized forms of the two periplasmic domains of N. meningitidis DsbD, n-NmDsbD and c-NmDsbD. The backbone amide resonances in all four forms were completely assigned, and the secondary structures for the core regions of the proteins were calculated using 13Cαβ shifts. The reduced and oxidized forms of each domain have similar secondary shifts suggesting they retain the same fold. We anticipate that these data will provide an important basis for studying the interaction between n-NmDsbD and c-NmDsbD, which is required for electron transfer across the bacterial cytoplasmic membrane.

  • Backbone NMR assignments of tryparedoxin, the central protein in the
           hydroperoxide detoxification cascade of African trypanosomes, in the
           oxidized and reduced form
    • Authors: Annika Wagner; Erika Diehl; R. Luise Krauth-Siegel; Ute A. Hellmich
      Abstract: Tryparedoxin (Tpx) is a pivotal protein in the redox-metabolism of trypanosomatid parasites. Tpx has previously been identified as a potential target for drug development in the fight against human African sleeping sickness caused by Trypanosoma brucei. Tpx belongs to the thioredoxin superfamily and acts as an oxidoreductase in the parasite’s cytoplasm. It contains a WCPPC active site motif, which enables the protein to undergo thiol-disulfide exchange. To promote future protein-drug interaction analyses, we report the 1H, 13C and 15N backbone chemical shift assignments for both the oxidized and reduced states of Tpx. The redox state of the protein has a significant impact on the chemical shifts of the residues at the active site of the protein, especially on the two redox active site cysteines. The NMR assignments presented here will be a prerequisite for investigating drug binding to Tpx in molecular detail and to drive further drug optimization.

  • 1 H, 13 C, and 15 N backbone and sidechain resonance assignments of a
           monomeric variant of E. coli deoxyribose-5-phosphate aldolase
    • Authors: Marianne Schulte; Matthias Stoldt; Philipp Neudecker; Jӧrg Pietruszka; Dieter Willbold; Vineet Panwalkar
      Abstract: Deoxyribose-5-phosphate aldolase (DERA) catalyses the reversible conversion of 2-deoxyribose-5-phosphate (dR5P) into glyceraldehyde-3-phosphate (G3P) and acetaldehyde. For industrial applications, this enzyme is used in organic synthesis for aldol reactions between acetaldehyde as a donor and a wide range of aldehydes as acceptors. Here, we present a near complete set of sequence-specific 1H, 13C and 15N resonance assignments of a 28 kDa monomeric variant of the Escherichia coli DERA. These assignments provide the basis for ongoing structural and dynamic analysis of DERA substrate specificity.

  • 1 H, 13 C and 15 N backbone chemical shift assignments of camelid
           single-domain antibodies against active state µ-opioid receptor
    • Authors: Remy Sounier; Yinshan Yang; Joanna Hagelberger; Sébastien Granier; Hélène Déméné
      Abstract: Nanobodies are single chain antibodies that have become a highly valuable and versatile tool for biomolecular and therapeutic research. One application field is the stabilization of active states of flexible proteins, among which G-protein coupled receptors represent a very important class of membrane proteins. Here we present the backbone and side-chain assignment of the 1H, 13C and 15N resonances of Nb33 and Nb39, two nanobodies that recognize and stabilize the µ-opioid receptor to opioids in its active agonist-bound conformation. In addition, we present a comparison of their secondary structures as derived from NMR chemical shifts.

  • NMR resonance assignments of the FKBP domain of human aryl hydrocarbon
           receptor-interacting protein-like 1 (AIPL1) in complex with a farnesyl
           ligand
    • Authors: Liping Yu; Ravi P. Yadav; Nikolai O. Artemyev
      Abstract: Aryl hydrocarbon receptor-interacting protein-like 1 (AIPL1) is a specialized chaperone of phosphodiesterase 6, a key effector enzyme in the phototransduction cascade. The FKBP domain of AIPL1 is known to bind the farnesyl moiety of PDE6. Mutations in AIPL1, including many missense mutations in the FKBP domain, have been associated with Leber congenital amaurosis, a severe blinding disease. Here, we report the backbone and sidechain assignments of the N-terminal FKBPΔloop (with a loop deletion) of AIPL1 in complex with a farnesyl ligand. We also compare the predicted secondary structures of FKBPΔloop with those of a highly homologous AIP FKBP. These results show that the FKBP domains of AIP and AIPL1 have similar folds, but display subtle differences in structure and dynamics. Therefore, these assignments provide a framework for further elucidation of the mechanism of farnesyl binding and the function of AIPL1 FKBP.

  • 1 H, 13 C and 15 N backbone and side-chain resonance assignments of the
           ZnF-UBP domain of USP20/VDU2
    • Authors: Yuanyuan Yang; Yi Wen; Naixia Zhang
      Abstract: Deubiquitinase USP20/VDU2 has been identified as a regulator of multiple proteins including hypoxia-inducible factor (HIF)-1α, β2-adrenergic receptor, and tumor necrosis factor receptor associated factor 6 etc. It contains four structural domains, including an N-terminal zinc-finger ubiquitin binding domain (ZnF-UBP) that potentially helps USP20 to recruit its ubiquitin substrates. Here we report the 1H, 13C and 15N backbone and side-chain resonance assignments of the ZnF-UBP domain of USP20/VDU2. The BMRB accession number is 26901. The secondary structural elements predicted from the NMR data reveal a global fold consisting of three α-helices and four β-strands. The complete assignments can be used to explore the protein dynamics of the USP20 ZnF-UBP and its interactions with monoubiquitin and ubiquitin chains.

  • NMR assignments and ligand-binding studies on a two-domain family GH19
           chitinase allergen from Japanese cedar ( Cryptomeria japonica ) pollen
    • Authors: Tomoya Takashima; Takayuki Ohnuma; Tamo Fukamizo
      Abstract: A two-domain family GH19 chitinase from Japanese cedar (Cryptomeria japonica) pollen, CJP-4, which consists of an N-terminal CBM18 domain and a GH19 catalytic domain, is known to be an important allergen, that causes pollinosis. We report here the resonance assignments of the NMR spectrum of CJP-4. The backbone resonances were almost completely assigned, and the secondary structure was estimated based on the chemical shift values. The addition of a chitin dimer to the enzyme solution perturbed the chemical shifts of the resonances of amino acid residues forming a long extended binding site spanning from the CBM18 domain to the GH19 catalytic domain.

  • 13 C and 15 N chemical shift assignments of mammalian Y145Stop prion
           protein amyloid fibrils
    • Authors: Theint Theint; Philippe S. Nadaud; Krystyna Surewicz; Witold K. Surewicz; Christopher P. Jaroniec
      Abstract: The Y145Stop prion protein (PrP23-144), which has been linked to the development of a heritable prionopathy in humans, is a valuable in vitro model for elucidating the structural and molecular basis of amyloid seeding specificities. Here we report the sequential backbone and side-chain 13C and 15N assignments of mouse and Syrian hamster PrP23-144 amyloid fibrils determined by using 2D and 3D magic-angle spinning solid-state NMR. The assigned chemical shifts were used to predict the secondary structures for the core regions of the mouse and Syrian hamster PrP23-144 amyloids, and the results compared to those for human PrP23-144 amyloid, which has previously been analyzed by solid-state NMR techniques.

  • 1 H, 15 N, 13 C backbone resonance assignments of human soluble catechol O
           -methyltransferase in complex with S -adenosyl- l -methionine and
           3,5-dinitrocatechol
    • Authors: Sylwia Czarnota; Nicola J. Baxter; Matthew J. Cliff; Jonathan P. Waltho; Nigel S. Scrutton; Sam Hay
      Abstract: Catechol O-methyltransferase (COMT) is an enzyme that plays a major role in catechol neurotransmitter deactivation. Inhibition of COMT can increase neurotransmitter levels, which provides a means of treatment for Parkinson’s disease, schizophrenia and depression. COMT exists as two isozymes: a soluble cytoplasmic form (S-COMT), expressed in the liver and kidneys and a membrane-bound form (MB-COMT), found mostly in the brain. Here we report the backbone 1H, 15N and 13C chemical shift assignments of S-COMT in complex with S-adenosyl-l-methionine, 3,5-dinitrocatechol and Mg2+. Assignments were obtained by heteronuclear multidimensional NMR spectroscopy. In total, 97 % of all backbone resonances were assigned in the complex, with 205 out of a possible 215 residues assigned in the 1H-15N TROSY spectrum. Prediction of solution secondary structure from a chemical shift analysis using the TALOS+ webserver is in good agreement with published X-ray crystal structures.

  • Backbone chemical shift assignments and secondary structure analysis of
           the U1 protein from the Bas-Congo virus
    • Authors: Garry W. Buchko; Matthew C. Clifton; Ellen G. Wallace; Kateri A. Atkins; Peter J. Myler
      Abstract: The Bas-Congo virus (BASV) is the first rhabdovirus associated with a human outbreak of acute hemorrhagic fever. The single-stranded, negative-sense RNA genome of BASV contains the five core genes present in all rhabdoviral genomes plus an additional three genes, annotated U1, U2, and U3, with weak (<21%) sequence similarity only to a handful of genes observed in a few other rhabdoviral genomes. The function of the rhabdoviral U proteins is unknown, but, they are hypothesized to play a role in viral infection or replication. To better understand this unique family of proteins, a construct containing residues 27–203 of the 216-residue U1 protein (BASV-U1*) was prepared. By collecting data in 0.5 M urea it was possible to eliminate transient association enough to enable the assignment of most of the observable 1HN, 1Hα, 15N, 13Cα, 13Cβ, and 13C´ chemical shifts for BASV-U1* that will provide a foundation to study its solution properties. The analyses of these chemical shifts along with 15N-edited NOESY data enabled the identification of the elements of secondary structure present in BASV-U1*.

  • Backbone resonance assignments of the F-actin binding domain of mouse
           αN-catenin
    • Abstract: α-Catenin is a filamentous actin (F-actin) binding protein that links the classical cadherin–catenin complex to the actin cytoskeleton at adherens junctions (AJs). Its C-terminal F-actin binding domain is required for regulating the dynamic interaction between AJs and the actin cytoskeleton during tissue development. Thus, obtaining the molecular details of this interaction is a crucial step towards understanding how α-catenin plays critical roles in biological processes, such as morphogenesis, cell polarity, wound healing and tissue maintenance. Here we report the backbone atom (1HN, 15N, 13Cα, 13Cβ and 13C′) resonance assignments of the C-terminal F-actin binding domain of αN-catenin.

  • NMR assignments for the insertion domain of bacteriophage Sf6 coat protein
    • Abstract: The P22 bacteriophage group is a subgroup of the λ phage supercluster, comprised of the three major sequence types Sf6, P22, and CUS-3, based on their capsid proteins. Our goal is to investigate the extent to which structure–function relationships are conserved for the viral coat proteins and I-domains in this subgroup. Sf6 is a phage that infects the human pathogen Shigella flexneri. The coat protein of Sf6 assembles into a procapsid, which further undergoes maturation during DNA packaging into an infectious virion. The Sf6 coat protein contains a genetically inserted domain, termed the I-domain, similar to the ones present in the P22 and CUS-3 coat proteins. Based on the P22 example, I-domains play important functional roles in capsid assembly, stability, viability, and size-determination. Here we report the 1H, 15N, and 13C chemical shift assignments for the I-domain of the Sf6 phage coat protein. Chemical shift-based secondary structure prediction and hydrogen-bond patterns from a long-range HNCO experiment indicate that the Sf6 I-domain adopts a 6-stranded β-barrel fold like those of P22 and CUS-3 but with important differences, including the absence of the D-loop that is critical for capsid assembly and the addition of a novel disordered loop region.

  • Backbone assignment of the binary complex of the full length Sulfolobus
           solfataricus DNA polymerase IV and DNA
    • Authors: Eunjeong Lee; Jason D. Fowler; Zucai Suo; Zhengrong Wu
      Abstract: Sulfolobus solfataricus DNA polymerase IV (Dpo4), a model Y-family DNA polymerase, bypasses a wide range of DNA lesions in vitro and in vivo. In this paper, we report the backbone chemical shift assignments of the full length Dpo4 in its binary complex with a 14/14-mer DNA substrate. Upon DNA binding, several β-stranded regions in the isolated catalytic core and little finger/linker fragments of Dpo4 become more structured. This work serves as a foundation for our ongoing investigation of conformational dynamics of Dpo4 and future determination of the first solution structures of a DNA polymerase and its binary and ternary complexes.
