The interleukin-4-inducing principle from Schistosoma mansoni eggs (IPSE/alpha-1) is a major immunogenic component of schistosomes. It potently triggers the release of interleukin-4 from
basophilic granulocytes in an IgE-dependent manner, suggesting a key function in the modulation of the host’s immune response
to Schistosoma mansoni infection. Here we present the near complete assignment of an IPSE/alpha-1 variant, IPSEΔNLS, which comprises the core domain
of the protein. 相似文献

Galectin-1 is an important regulator of leukocyte function and tumor angiogenesis. Recently, this lectin has been identified
as a molecular target for the potent angiogenesis inhibitor anginex. Here, we report 1H, 13C, and 15N chemical shift assignments for human galectin-1 as determined by using heteronuclear triple resonance NMR spectroscopy. 相似文献

1H, 15N and 13C chemical shift assignments for the winged helix domains of two archeal MCM C-termini

High-fidelity replication guarantees the stable inheritance of genetic information stored in the DNA of living organisms. The minichromosome maintenance (MCM) complex functions as replicative DNA-unwinding helicase and has been identified as one key player in the replication process of archea and eukarya. Despite the availability of considerable structural information on archeal MCMs, such information was missing for their C-terminal domain. In order to obtain more detailed structural information, we assigned the NMR chemical shifts for backbone and side chain nuclei for the MCM C-terminal winged helix domains of the archeal species Methanothermobacter thermautrophicus and Sulfolobus solfataricus. 相似文献

The agglutinin-like-sequence (ALS) family of adhesion proteins are a key virulence factor for C. albicans. These proteins have been implicated in several functions, notably adhesion and invasion of different cell types, as well as binding to peptides and proteins in the cell surface and extracellular matrix. In order to understand their binding mechanism and en route to a full structural determination by NMR, here we report the resonance assignments of backbone atoms plus Ile, Leu and Val methyls for residues 18–329 of ALS1, which comprises the 33.5 kDa binding domain. 相似文献

Human interferon-stimulated gene 15 protein (ISG15), also called ubiquitin cross-reactive protein (UCRP), is the first identified
ubiquitin-like protein containing two ubiquitin-like domains fused in tandem. The active form of ISG15 is conjugated to target
proteins via the C-terminal glycine residue through an isopeptide bond in a manner similar to ubiquitin. The biological role
of ISG15 is strongly associated with the modulation of cell immune function, and there is mounting evidence suggesting that
many viral pathogens evade the host innate immune response by interfering with ISG15 conjugation to both host and viral proteins
in a variety of ways. Here we report nearly complete backbone 1HN, 15N, 13C′, and 13Cα, as well as side chain 13Cβ, methyl (Ile-δ1, Leu, Val), amide (Asn, Gln), and indole N–H (Trp) NMR resonance assignments for the 157-residue human ISG15
protein. These resonance assignments provide the basis for future structural and functional solution NMR studies of the biologically
important human ISG15 protein. 相似文献

NOXO1 (Nox Organizer 1) is a homolog of the NAPDH oxidase protein p47
phox
. NADPH oxidases transfer electrons from NADPH to molecular oxygen, generating the superoxide anion. NOXO1 contains an N-terminal
PX (phox homology) domain and is one of several PX domain-containing proteins found in the cytosolic subunits of the NADPH
oxidase complex. These PX domains bind to membrane lipids and target the protein to membranes, recruiting other cytosolic
components to the membrane bound components and aiding formation of a active enzyme complex. This recruitment represents a
level of regulation of these oxidases. Here we report the backbone assignments of NOXO1β PX. 相似文献

The ζ-COP is one subunit of the COP I coatomer, which mediates the protein trafficking from the cis-Golgi complex to the endoplasmic
reticulum and also functions in the intra-Golgi trafficking. The NMR assignments of the ζ-COP are essential for its solution
structure determination. 相似文献

Vta1 and Vps60 are two ESCRT associated proteins, their direct interaction enhances Vps4 ATPase activity. The N-terminal domain of Vta1 (residues 1–167aa, named as Vta1NTD) contains two tandem MIT domains, which specifically recognize Vps60 and Did2 but not other ESCRT-III subunits. The fragment Vps60 (128–186aa) was reported to display full activity of Vps60, which stimulates Vps4 ATPase in a Vta1-dependent manner. To study the structural basis for the interaction between Vta1 and Vps60, as a first step, here, we report the resonance assignments of the sequential backbone atoms and the side chains of the residues in the two components of Vta1NTD/Vps60128–186 complex at pH 7.0 and 20 °C (BMRB No. 18521). 相似文献

Human regenerating (Reg) genes belong to the C-type lectin superfamily and express secretory proteins in various tissues. Reg Iα, also named lithostathine, has multiple roles in numerous biological events such as cytokines, anti-apoptotic factors and the calcium carbonate crystals inhibitor. Under physiological pH, Reg Iα becomes largely insoluble after a self-proteolysis process, and the N-terminally truncated form readily polymerizes into fibrils, which leads to neurodegenerative diseases. Reg Iα may form protofibril via lateral hydrophobic interactions with a native-like conformation. The structural basis from the native to fibril form, as well as the carbohydrate binding sites on Reg Iα, remain unknown. Here we present the NMR backbone and side-chain assignments of Reg Iα for use in further NMR investigations. 相似文献

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. 相似文献

Alpha(1)-antitrypsin is a 45-kDa (394-residue) serine protease inhibitor synthesized by hepatocytes, which is released into the circulatory system and protects the lung from the actions of neutrophil elastase via a conformational transition within a dynamic inhibitory mechanism. Relatively common point mutations subvert this transition, causing polymerisation of α(1)-antitrypsin and deficiency of the circulating protein, predisposing carriers to severe lung and liver disease. We have assigned the backbone resonances of α(1)-antitrypsin using multidimensional heteronuclear NMR spectroscopy. These assignments provide the starting point for a detailed solution state characterization of the structural properties of this highly dynamic protein via NMR methods. 相似文献

Galectins are multifunctional proteins with carbohydrate/protein-binding properties and distinct expression profiles. Homodimeric galectin-7 (p53-induced gene 1) is a potent pro-apoptotic effector with clinical relevance. Here, we report (1)H, (13)C, and (15)N chemical shift assignments for human galectin-7 dimer as determined by using heteronuclear, triple resonance NMR spectroscopy. 相似文献

GrxS14 is a monothiol Glutaredoxin (Grx) from Populus tremula × tremuloides, which has a CGFS active site. GrxS14 is located in the chloroplasts and has been found to occur ether as an apo form or
as a holo form with a [2Fe-2S] cluster. The holo form contains two monomers of apo GrxS14 bridged by the iron sulphur center,
in the presence of two external glutathione molecules (Bandyopadhyay et al. 2008). The NMR assignments of the GrxS14 are essential for its solution structure determination. 相似文献

β-Lactamases inactivate β-lactam antibiotics by hydrolysis of their endocyclic β-lactam bond and are a major cause of antibiotic resistance in pathogenic bacteria. The zinc dependent metallo-β-lactamase enzymes are of particular concern since they are located on highly transmissible plasmids and have a broad spectrum of activity against almost all β-lactam antibiotics. We present here essentially complete (>96 %) backbone and sidechain sequence-specific NMR resonance assignments for the Bacillus cereus subclass B1 metallo-β-lactamase, BcII, and for its complex with R-thiomandelic acid, a broad spectrum inhibitor of metallo-β-lactamases. These assignments have been used as the basis for determination of the solution structures of the enzyme and its inhibitor complex and can also be used in a rapid screen for other metallo-β-lactamase inhibitors. 相似文献
