Crystallization and preliminary X-ray crystallographic analysis of the GluR0 ligand-binding core from Nostoc punctiforme.

ABSTRACT: GluR0 from Nostoc punctiforme (NpGluR0) is a bacterial homologue of the ionotropic glutamate receptor. The ligand-binding core of NpGluR0 was crystallized at 294 K using the hanging-drop vapour-diffusion method. The L-glutamate-complexed crystal belongs to space group C222(1), with unit-cell parameters a = 78.0, b = 145.1, c = 132.1 A. The crystals contain three subunits in the asymmetric unit, with a VM value of 2.49 A3 Da(-1). The diffraction limit of the L-glutamate complex data set was 2.1 A using synchrotron X-ray radiation at beamline BL-4A of the Pohang Accelerator Laboratory (Pohang, Korea).

Crystallization and preliminary X-ray crystallographic analysis of ligand-free and arginine-bound forms of Thermotoga maritima arginine-binding protein.

Project description:The arginine-binding protein from Thermotoga maritima (TmArgBP) is an arginine-binding component of the ATP-binding cassette (ABC) transport system in this hyperthermophilic bacterium. This protein is endowed with an extraordinary stability towards thermal and chemical denaturation. Its structural characterization may provide useful insights for the clarification of structure-stability relationships and for the design of new biosensors. Crystallization trials were set up for both arginine-bound and ligand-free forms of TmArgBP and crystals suitable for crystallographic investigations were obtained for both forms. Ordered crystals of the arginine adduct of TmArgBP could only be obtained by using the detergent LDAO as an additive to the crystallization medium. These crystals were hexagonal, with unit-cell parameters a = 78.2, c = 434.7 Å, and diffracted to 2.7 Å resolution. The crystals of the ligand-free form were orthorhombic, with unit-cell parameters a = 51.8, b = 91.9, c = 117.9 Å, and diffracted to 2.25 Å resolution.

Crystallization and preliminary X-ray crystallographic analysis of the oxysterol-binding protein Osh3 from Saccharomyces cerevisiae.

Project description:Oxysterol-binding protein (OSBP) related proteins (ORPs) are conserved from yeast to humans and are implicated in regulation of sterol homeostasis and in signal transduction pathways. Osh3 of Saccharomyces cerevisiae is a pleckstrin-homology (PH) domain-containing ORP member that regulates phosphoinositide metabolism at endoplasmic reticulum-plasma membrane contact sites. The N-terminal PH domain of Osh3 was purified and crystallized as a lysozyme fusion and the resulting crystal diffracted to 2.3?Å resolution. The crystal belonged to the monoclinic space group C2, with unit-cell parameters a=98.03, b=91.31, c=84.13?Å, ?=81.41°. With two molecules in the asymmetric unit, the Matthews coefficient was 3.13?Å3?Da(-1). Initial attempts to solve the structure by molecular-replacement techniques using T4 lysozyme as a search model were successful. The C-terminal OSBP-related domain (OBD) of Osh3 was crystallized by the vapour-diffusion method and the resulting crystal diffracted to 1.5?Å resolution. The crystal was orthorhombic, belonging to space group P2(1)2(1)2(1), with unit-cell parameters a=41.57, b=87.52, c=100.58?Å. With one molecule in the asymmetric unit, the Matthews coefficient was 2.01?Å3?Da(-1).

Crystallization and preliminary X-ray crystallographic analysis of the membrane-binding haemprotein nitrophorin 7 from Rhodnius prolixus.

Project description:Nitrophorins (nitric oxide transport proteins) are haemproteins originating from the blood-feeding insect Rhodnius prolixus. They consist of an eight-stranded ?-barrel, which classifies them into the lipocalin family. Nitrophorin 7 (NP7) and the E27V mutant protein NP7(E27V) were crystallized at 277?K using the vapour-diffusion method with PEG as the precipitating agent. Data sets for wild-type NP7 and NP7(E27V) were collected to 1.80 Å resolution from single crystals at 100 K using synchrotron radiation. The crystals belonged to space group P2(1), with unit-cell parameters a = 38, b = 67, c = 39 Å, ? = 117°. The crystal contained one molecule per asymmetric unit, with a Matthews coefficient (V(M)) of 2.11 Å(3) Da(-1); the solvent content was estimated to be 41.8%.

Crystallization and preliminary X-ray crystallographic analysis of an ice-binding protein (FfIBP) from Flavobacterium frigoris PS1.

Project description:Ice growth in a cold environment is fatal for polar organisms, not only because of the physical destruction of inner cell organelles but also because of the resulting chemical damage owing to processes such as osmotic shock. The properties of ice-binding proteins (IBPs), which include antifreeze proteins (AFPs), have been characterized and IBPs exhibit the ability to inhibit ice growth by binding to specific ice planes and lowering the freezing point. An ice-binding protein (FfIBP) from the Gram-negative bacterium Flavobacterium frigoris PS1, which was isolated from the Antarctic, has recently been overexpressed. Interestingly, the thermal hysteresis activity of FfIBP was approximately 2.5?K at 50?µM, which is ten times higher than that of the moderately active IBP from Arctic yeast (LeIBP). Although FfIBP closely resembles LeIBP in its amino-acid sequence, the antifreeze activity of FfIBP appears to be much greater than that of LeIBP. In an effort to understand the reason for this difference, an attempt was made to solve the crystal structure of FfIBP. Here, the crystallization and X-ray diffraction data of FfIBP are reported. FfIBP was crystallized using the hanging-drop vapour-diffusion method with 0.1?M sodium acetate pH 4.4 and 3?M sodium chloride as precipitant. A complete diffraction data set was collected to a resolution of 2.9?Å. The crystal belonged to space group P4(1)22, with unit-cell parameters a = b = 69.4, c = 178.2?Å. The asymmetric unit contained one monomer.

Crystallization and preliminary X-ray crystallographic analysis of Sulfolobus solfataricus thioredoxin reductase.

Project description:A thermostable thioredoxin reductase isolated from Sulfolobus solfataricus (SsTrxR) has been successfully crystallized in the absence and in the presence of NADP. Two different crystal forms have been obtained. Crystals of the form that yields higher resolution data (1.8 A) belong to space group P2(1)2(1)2(1), with unit-cell parameters a = 76.77, b = 120.68, c = 126.85 A. The structure of the enzyme has been solved by MAD methods using the anomalous signal from the Se atoms of selenomethionine-labelled SsTrxR.

Crystallization and preliminary X-ray crystallographic analysis of a bacterial Asn-transamidosome.

Project description:Most canonical aminoacyl-tRNAs are synthesized directly by their cognate aminoacyl-tRNA synthetases (aaRSs), but glutaminyl-tRNA(Gln) and asparaginyl-tRNA(Asn) are synthesized indirectly by two-step processes. These processes are catalyzed by the transamidosome, a large ribonucleoprotein particle composed of GatA, GatB, GatC, aaRS and tRNA. In this study, the Asn-transamidosome from Pseudomonas aeruginosa was reconstructed and crystallized by mixing purified GatCAB complex, AspRS and tRNA(Asn). The crystal of the Asn-transamidosome belonged to space group P2?, with unit-cell parameters a=93.3, b=186.0, c=287.8?Å, ?=93.3°, and diffracted to 3.73?Å resolution. Preliminary X-ray crystallographic analysis showed that the asymmetric unit contained two Asn-transamidosomes, each composed of two GatCABs, one AspRS dimer and two tRNAAsns, indicating that the construction of the current Asn-transamidosome differs from that of Thermus thermophilus.
