  • Resonance assignment of the ribosome binding domain of E. coli ribosomal
           protein S1
    • Abstract: Abstract Ribosomal protein S1 is an essential actor for protein synthesis in Escherichia coli. It is involved in mRNA recruitment by the 30S ribosomal subunit and recognition of the correct start codon during translation initiation. E. coli S1 is a modular protein that contains six repeats of an S1 motif, which have distinct functions despite structural homology. Whereas the three central repeats have been shown to be involved in mRNA recognition, the two first repeats that constitute the N-terminal domain of S1 are responsible for binding to the 30S subunit. Here we report the almost complete 1H, 13C and 15N resonance assignment of two fragments of the 30S binding region of S1. The first fragment comprises only the first repeat. The second corresponds to the entire ribosome binding domain. Since S1 is absent from all high resolution X-ray structures of prokaryotic ribosomes, these data provide a first step towards atomic level structural characterization of this domain by NMR. Chemical shift analysis of the first repeat provides evidence for structural divergence from the canonical OB-fold of an S1 motif. In contrast the second domain displays the expected topology for an S1 motif, which rationalizes the functional specialization of the two subdomains.

  • Backbone, side chain and heme resonance assignments of the triheme
           cytochrome PpcD from Geobacter sulfurreducens
    • Abstract: Abstract Gene knock-out studies on Geobacter sulfurreducens (Gs) cells showed that the periplasmic triheme cytochrome PpcD is involved in respiratory pathways leading to the extracellular reduction of Fe(III) and U(VI) oxides. More recently, it was also shown that the gene encoding for PpcD has higher transcript abundance when Gs cells utilize graphite electrodes as sole electron donors to reduce fumarate. This sets PpcD as the first multiheme cytochrome to be involved in Gs respiratory pathways that bridge the electron transfer between the cytoplasm and cell exterior in both directions. Nowadays, extracellular electron transfer (EET) processes are explored for several biotechnological applications, which include bioremediation, bioenergy and biofuel production. Therefore, the structural characterization of PpcD is a fundamental step to understand the mechanisms underlying EET. However, compared to non-heme proteins, the presence of numerous proton-containing groups in the redox centers presents additional challenges for protein signal assignment and structure calculation. Here, we report the complete assignment of the heme proton signals together with 1H, 13C and 15N backbone and side chain assignments of the reduced form of PpcD.

  • Sequence-specific backbone 1 H, 13 C, and 15 N resonance assignments of
           human ribonuclease 4
    • Abstract: Abstract Human ribonuclease 4 (RNase 4) is the most evolutionarily conserved member of the 8 canonical human pancreatic-like RNases, showing more than 90 % identity with bovine and porcine homologues. The enzyme displays ribonucleolytic activity with a strong preference for uracil-containing RNA substrates, a feature only shared with human eosinophil derived-neurotoxin (EDN, or RNase 2) and eosinophil cationic protein (ECP, or RNase 3). It is also the shortest member of the human family, with a significantly truncated C-terminal tail. Its unique active-site pocket and high degree of conservation among vertebrates suggest that the enzyme plays a crucial biological function. Here, we report on the 1H, 13C and 15N backbone resonance assignments of RNase 4, providing means to characterize its molecular function at the atomic level by NMR.

  • Assignments of RNase A by ADAPT-NMR and enhancer
    • Abstract: Abstract We report here backbone 1H and 15N assignments for ribonuclease A obtained by using ADAPT-NMR, a fully-automated approach for combined data collection, spectral analysis and resonance assignment. ADAPT-NMR was able to assign 98 % of the resonances with 93 % agreement with traditional data collection and assignment. Further refinement of the automated results with ADAPT-NMR enhancer led to complete (100 %) assignments with 96 % agreement with assignments by the traditional approach.

  • NMR resonance assignments of the archaeal ribosomal protein L7Ae in the
           apo form and bound to a 25 nt RNA
    • Abstract: Abstract The archaeal protein L7Ae forms part of a protein complex in the ribosome that specifically recognizes and binds to kink-turn RNA. In this complex, L7Ae directly interacts with the oligonucleotide and creates a functional arrangement for site-specific 2′-O-methylation. We report the solution NMR backbone assignment of Methanocaldococcus jannaschii L7Ae (117 residues, 12.7 kDa) in the ligand-free state and when bound to a 25 nucleotide C/D box kink-turn mimic RNA.

  • 1 H, 13 C and 15 N chemical shift assignments for the cyclic-nucleotide
           binding homology domain of a KCNH channel
    • Abstract: Abstract The KCNH family of ion channels plays important roles in heart and nerve cells. The C-terminal region of the KCNH channel contains a cyclic-nucleotide binding homology domain (CNBHD) which is important for channel gating through interaction with the eag domain. To study the solution structure of CNBHD of the KCNH channel of zebrafish, we over-expressed and purified this domain from E. coli. We report the resonance assignments of the CNBHD. The assignments will allow us to perform structural and dynamic studies for this domain, which will shed light on its role in channel gating.

    • Abstract: Abstract Neuroglobin is a globin present in the brain and retina of mammals. This hexacoordinated hemoprotein binds small diatomic molecules, albeit with lower affinity compared with other globins. We report here the resonance assignment of murine met-Neuroglobine, free and in complex with cyanide.

  • 1 H, 13 C and 15 N backbone assignment of the EC-1 domain of human
    • Abstract: Abstract The Extracellular 1 (EC1) domain of E-cadherin has been shown to be important for cadherin–cadherin homophilic interactions. Cadherins are responsible for calcium-mediated cell–cell adhesion located at the adherens junction of the biological barriers (i.e., intestinal mucosa and the blood–brain barrier (BBB)). Cadherin peptides can modulate cadherin interactions to improve drug delivery through the BBB. However, the mechanism of modulating the E-cadherin interactions by cadherin peptides has not been fully elucidated. To provide a basis for subsequent examination of the structure and peptide-binding properties of the EC1 domain of human E-cadherin using solution NMR spectroscopy, the 1H, 13C and 15N backbone resonance of the uniformly labeled-EC1 were assigned and the secondary structure was determined based on the chemical shift values. These resonance assignments are essential for assessing protein–ligand interactions and are reported here.

  • 13 C, 15 N and 1 H resonance assignments of receiver domain of ethylene
           receptor ETR1
    • Abstract: Abstract Ethylene plays versatile functions in regulating plant physiology. Although the high affinity ethylene receptor and its downstream regulators have been identified, the molecular recognition of the receptor interacting domains remains to be established. It has been speculated that the cytoplasmic signaling of the ethylene receptor is a two-component regulatory system involving the conserved receiver domain (RD). Here, we report the NMR chemical shift assignments for RD from Arabidopsis thaliana ethylene receptor ETR1. Nearly complete backbone and side-chain assignments were achieved at pH 6.0 and 25 °C. The assignments and backbone dynamics revealed the secondary structure and showed that ETR1-RD is a monomer in solution. These results will make it possible to monitor downstream binding partners and elucidates our understanding of phosphotransfer in the plant two-component regulatory system in the ethylene signaling pathway.

  • 1 H, 15 N and 13 C resonance assignments and secondary structure
           prediction of Q4D059, a conserved and kinetoplastid-specific hypothetical
           protein from Trypanosoma cruzi
    • Abstract: Abstract Trypanosoma cruzi is a human parasite that causes Chagas disease, an illness affecting millions of people and without an efficient treatment available. Sequencing the pathogen genome has revealed that near half of protein-coding genes correspond to hypothetical proteins of unknown function, increasing the possibilities for novel target discovery. Q4D059 is a putative essential hypothetical protein from T. cruzi and it is specific and conserved among the trypanosomatid genomes. Here, we report the sequential backbone and side chain resonance assignments and secondary structure analysis of Q4D059, as first step for protein structure determination, function elucidation and drug screening.

  • Backbone and side-chain NMR assignments for the C-terminal domain of
           mammalian Vps28
    • Abstract: Abstract Vps28 is one of four cytosolic proteins comprising the endosomal sorting complex required for transport I (ESCRT-I). ESCRT-I is involved in sorting ubiquitinated proteins to multivesicular bodies as well as in mediating budding of retroviruses. Here, we report the backbone and side-chain assignments of the mammalian C-terminal domain of Vps28 (mVps28CTD), which is involved in interactions with other ESCRT components. We also compare the predicted secondary structures of mVps28CTD with those of the published X-ray crystal structures of Saccharomyces cerevisiae and Xenopus laevis Vps28CTD. These NMR resonance assignments will facilitate chemical shift mapping and structural determination of mammalian Vps28 interactions with other components of the endosomal sorting machinery that sorts ubiquitinated proteins for lysosomal degradation.

           the 24 kDa plectin repeat domain 6 from human protein plectin
    • Abstract: Abstract The 500 kDa protein plectin is essential for the cytoskeletal organization of most mammalian cells and it is up-regulated in some types of cancer. Here, we report nearly complete sequence-specific polypeptide backbone, 13Cβ and methyl group resonance assignments for 24 kDa human plectin(4403–4606) containing the C-terminal plectin repeat domain 6.

  • 1 H, 13 C, and 15 N backbone and side-chain chemical shift assignments for
           the 36 proline-containing, full length 29 kDa human chimera-type
    • Abstract: Abstract Galectin-3, an adhesion/growth regulatory lectin, has a unique trimodular design consisting of the canonical carbohydrate recognition domain, a collagen-like tandem-repeat section, and an N-terminal peptide with two sites for Ser phosphorylation. Structural characterization of the full length protein with its non-lectin part (115 of 250 residues total) will help understand the multi functionality of this potent cellular effector. Here, we report 1H, 13C, and 15N chemical shift assignments as determined by heteronuclear NMR spectroscopy .

  • Backbone assignments of the apo and Zn(II) protoporphyrin IX-bound states
           of the soluble form of rat heme oxygenase-1
    • Abstract: Abstract In nature, heme is a prosthetic group that is universally used as a cofactor for heme proteins. It is necessary for the execution of fundamental biological processes including electron transfer, oxidation and metabolism. However, free heme is toxic to cells, because of its capability to enhance oxidative stress, hence its cellular concentration is strictly regulated through multiple mechanisms. Heme oxygenase (HO) serves as an irreplaceable member in the heme degradation system. It is a ubiquitous protein, existing in many species including mammals, higher plants, and interestingly, certain pathogenic bacteria. In the HO reaction, HO catalyzes oxidative cleavage of heme to generate biliverdin and release carbon monoxide and ferrous iron. Because of the beneficial effects of these heme catabolism products, HO plays a key role in iron homeostasis and in defense mechanism against oxidative stress. HO is composed of an N-terminal structured region and a C-terminal membrane-bound region. Furthermore, the soluble form of HO, which is obtainable by excision of the membrane-bound region, retains its catalytic activity. Here, we present the backbone resonance assignments of the soluble form (residues 1–232) of HO-1 in the free and Zn(II) protoporphyrin IX (ZnPP)-bound states, and analyzed the structural differences between the states. ZnPP is a potent enzyme inhibitor, and the ZnPP-bound structure of HO-1 mimics the heme-bound structure. These assignments provide the structural basis for a detailed investigation of the HO-1 function.

  • 1 H, 15 N and 13 C chemical shift assignments of the homeodomain of Hoxc9
           in complex with the cell cycle regulator Geminin
    • Abstract: Abstract Homeodomain-containing transcription factors including Hox proteins play fundamental roles in the regulation of different cellular and developmental processes. These proteins all contain a homeodomain, which is a 60-amino acid DNA binding domain encoded by a 180-base pair DNA sequence. Homeodomains also serve as protein interaction targets to regulate the functions of these transcription factors or other proteins. The cell cycle regulator Geminin interacts with Hox homeodomains to inhibit the transcription activities of Hox proteins and enrolls Hox proteins in the cell proliferation process. Here we report complete chemical shift assignments of the homeodomain of Hoxc9 (Hoxc9-HD) in complex with the homeodomain binding region of Geminin (Gem-HBR), which were determined by triple resonance NMR experiments. These resonance assignments provide a basis for the structure determination of the Hoxc9-HD/Gem-HBR complex and for the further study of homeodomains in complex with other regulatory protein partners (BMRB deposits with accession number 17407).

  • H N , N H , C α , C β , and methyl group assignments of filamin
           multidomain fragments IgFLNc4–5 and IgFLNa3–5
    • Abstract: Abstract Filamins regulate the actin cytoskeleton by cross-linking actin filaments, linking the cytoskeleton to the cell membrane, and through interaction with numerous binding partners such as intracellular signalling molecules, ion channels, receptors, enzymes and transcription factors. The rod region of filamins consists of 24 immunoglubulin (Ig)-like repeats, for some of which the functional unit is a domain pair. Our aim is to study filamin Ig domain–domain interactions and quaternary arrangement as well as to locate peptide binding sites on domain assemblies. We report here the HN, NH, Cα, Cβ, and methyl group assignments of filamin A three-domain fragment IgFLNa3–5 and filamin C two-domain fragment IgFLNc4–5.

  • 1 H, 13 C and 15 N resonance assignment of the mature form of monothiol
           glutaredoxin 1 from the pathogen Trypanosoma brucei
    • Abstract: Abstract Glutaredoxins (Grx) are small proteins, conserved throughout all the kingdoms of life, which are engaged in a wide variety of biological processes. According to the number of cysteines in their active site, Grx are classified as dithiolic or monothiolic (1-C-Grx). In most organisms, 1-C-Grx are implicated in iron-sulfur cluster (FeS) metabolism and utilize glutathione as cofactor. Trypanosomatids are parasitic protozoa of the order Kinetoplastida, which cause severe diseases in humans and domestic animals. These parasites exploit a unique thiol-dependent redox system based on bis(glutathionyl)spermidine (trypanothione) rather than on glutathione. Mitochondrial 1-C-Grx1 from trypanosomes differs from orthologues in several features including the use of trypanothione as ligand for FeS binding and the presence of a parasite-specific N-terminal extension. We have recently shown that 1-C-Grx1 from Trypanosoma brucei is indispensable for parasite survival in mouse, making this protein a potential drug target candidate against trypanosomiasis. However, structural information for the full-length form of 1-C-Grx1 is still lacking. Here, we report the NMR resonance assignment of the mature form of Tb1-C-Grx1 including an N-terminal tail, paving the way to disclose the role of this intrinsically disordered region in the protein function.
