Overproduction, purification, crystallization and preliminary X-ray analysis of the peroxiredoxin domain of a larger natural hybrid protein from Thermotoga maritima.

ABSTRACT: Thermotoga maritima contains a natural hybrid protein constituted of two moieties: a peroxiredoxin domain at the N-terminus and a nitroreductase domain at the C-terminus. The peroxiredoxin (Prx) domain has been overproduced and purified from Escherichia coli cells. The recombinant Prx domain, which is homologous to bacterial Prx BCP and plant Prx Q, folds properly into a stable protein that possesses biological activity. The recombinant protein was crystallized and synchrotron data were collected to 2.9 A resolution. The crystals belonged to the tetragonal space group I422, with unit-cell parameters a = b = 176.67, c = 141.20 A.

Project description:Adenosine triphosphate (ATP) binding cassette transporters (ABC transporters) are ATP hydrolysis-dependent transmembrane transporters. Here, the overproduction, purification and crystallization of the putative ABC transporter ATP-binding protein TM0222 from Thermotoga maritima are reported. The protein was crystallized in the hexagonal space group P6(4)22, with unit-cell parameters a = b = 148.49, c = 106.96 A, gamma = 120.0 degrees . Assuming the presence of two molecules in the asymmetric unit, the calculated V(M) is 2.84 A(3) Da(-1), which corresponds to a solvent content of 56.6%. A three-wavelength MAD data set was collected to 2.3 A resolution from SeMet-substituted TM0222 crystals. Data sets were collected on the BL38B1 beamline at SPring-8, Japan.

The unit-cell parameters of the crystals were a = b = 123.2, c = 35.6 A. Microseeding and further optimization yielded crystals with an X-ray diffraction limit of 2.36 A. A single 70 degrees data set was collected and processed, resulting in an overall R(merge) and a completeness of 9.5% and 99.3%, respectively.

Overexpression, crystallization, and preliminary X-ray crystallographic analysis of shikimate dehydrogenase from Thermotoga maritima.

Project description:Shikimate dehydrogenase (SDH), which catalyses the NADPH-dependent reduction of 3-dehydroshikimate to shikimate in the shikimate pathway, is an attractive target for the development of herbicides and antimicrobial agents. Previous structural studies showed that SDH exists in two conformations, an open form and a closed form, and it is believed that the conformational state is crucial to understanding a catalytic mechanism. To facilitate further structural comparisons among SDHs, structural analysis of an SDH from Thermotoga maritima encoded by the Tm0346 gene has been initiated. SDH from T. maritima has been overexpressed in Escherichia coli and crystallized at 296?K using ammonium sulfate as a precipitant. Crystals of T. maritima SDH diffracted to 1.45?Å resolution and belonged to orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a=54.21, b=62.45 and c=68.68?Å. The asymmetric unit contains a monomer, with a corresponding VM of 2.01?Å3?Da(-1) and a solvent content of 38.9% by volume.

Crystallization and preliminary X-ray diffraction analysis of the S-adenosylhomocysteine hydrolase (SAHH) from Thermotoga maritima.

Project description:S-Adenosylhomocysteine hydrolase (SAHH) catalyzes the reversible conversion of S-adenosylhomocysteine into adenosine and homocysteine. The SAHH from Thermotoga maritima (TmSAHH) was expressed in Escherichia coli and the recombinant protein was purified and crystallized. TmSAHH crystals belonging to space group C2, with unit-cell parameters a=106.3, b=112.0, c=164.9?Å, ?=103.5°, were obtained by the sitting-drop vapour-diffusion method and diffracted to 2.85?Å resolution. Initial phase determination by molecular replacement clearly indicated that the crystal contains one homotetramer per asymmetric unit. Further refinement of the crystal structure is in progress.

Expression, purification, crystallization and preliminary X-ray diffraction analysis of Thermotoga neapolitana beta-glucosidase B.

Project description:Beta-glucosidases belong to families 1, 3 and 9 of the glycoside hydrolases and act on cello-oligosaccharides. Family 1 and 3 enzymes are retaining and are reported to have transglycosylation activity, which can be used to produce oligosaccharides and glycoconjugates.

Crystals of selenomethionine-substituted protein have also been grown. The crystals belong to space group C222(1), with unit-cell parameters a = 74.9, b = 127.0, c = 175.2 A. Native data have been collected to 2.4 A resolution and the structure has been solved to 2.7 A using the selenomethionine MAD method. Model building and refinement of the structure are under way.

Overproduction, purification, crystallization and preliminary X-ray diffraction analysis of Trypanosoma brucei gambiense glycerol kinase.

Project description:In the bloodstream forms of human trypanosomes, glycerol kinase (GK; EC 2.7.1.30) is one of the nine glycosomally compartmentalized enzymes that are essential for energy metabolism. In this study, a recombinant Trypanosoma brucei gambiense GK (rTbgGK) with an N-terminal cleavable His(6) tag was overexpressed, purified to homogeneity and crystallized by the sitting-drop vapour-diffusion method using PEG 400 as a precipitant. A complete X-ray diffraction data set to 2.75 A resolution indicated that the crystals belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 63.84, b = 121.50, c = 154.59 A. The presence of two rTbgGK molecules in the asymmetric unit gives a Matthews coefficient (V(M)) of 2.5 A(3) Da(-1), corresponding to 50% solvent content.

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.

Purification, crystallization, crystallographic analysis and phasing of the CRISPR-associated protein Csm2 from Thermotoga maritima.

Project description:The clusters of regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated proteins (Cas) system consists of an intriguing machinery of proteins that confer bacteria and archaea with immunity against phages and plasmids via an RNA-guided interference mechanism. Here, the cloning, recombinant expression in Escherichia coli BL21 (DE3), purification, crystallization and preliminary X-ray diffraction analysis of Csm2 from Thermotoga maritima are reported. Csm2 is thought to be a component of an important protein complex of the type IIIA CRISPR-Cas system, which is involved in the CRISPR-Cas RNA-guided interference pathway. The structure of Csm2 was solved via cadmium single-wavelength anomalous diffraction (Cd-SAD) phasing. Owing to its involvement in the CRISPR-Cas system, the crystal structure of this protein could be of importance in elucidating the mechanism of type IIIA CRISPR-Cas systems in bacteria and archaea.
