Crystallization and preliminary X-ray data analysis of a DJ-1 homologue from Arabidopsis thaliana (AtDJ-1D).

ABSTRACT: A DJ-1 homologue protein from Arabidopsis thaliana (AtDJ-1D) belongs to the DJ-1/ThiJ/Pfpl superfamily and contains two tandem arrays of DJ-1-like sequences, but no structural information is available to date for this protein. AtDJ-1D was expressed in Escherichia coli, purified and crystallized for structural analysis. A crystal of AtDJ-1D was obtained by the hanging-drop vapour-diffusion method using 0.22 M NaCl, 0.1 M bis-tris pH 6.5, 21% polyethylene glycol 3350. AtDJ-1D crystals belonged to the monoclinic space group P2(1), with unit-cell parameters a = 56.78, b = 75.21, c = 141.68 Å, ? = 96.87°, and contained a trimer in the asymmetric unit. Diffraction data were collected to 2.05 Å resolution. The structure of AtDJ-1D has been determined using the multiple-wavelength anomalous dispersion (MAD) method.

Crystallization and preliminary X-ray analysis of cryptochrome 3 from Arabidopsis thaliana.

Project description:Cryptochromes are flavoproteins which serve as blue-light receptors in plants, animals, fungi and prokaryotes and belong to the same protein family as the catalytically active DNA photolyases. Cryptochrome 3 from the plant Arabidopsis thaliana (cry3; 525 amino acids, 60.7 kDa) is a representative of the novel cryDASH subfamily of UV-A/blue-light receptors and has been expressed as a mature FAD-containing protein in Escherichia coli without the signal sequence that directs the protein into plant organelles. The purified cryptochrome was found to be complexed to methenyltetrahydrofolate as an antenna pigment. Crystals of the cryptochrome-antenna pigment complex were obtained by vapour diffusion and display orthorhombic symmetry, with unit-cell parameters a = 76.298, b = 116.782, c = 135.024 A. X-ray diffraction data were collected to 1.9 A resolution using synchrotron radiation. The asymmetric unit comprises a cry3 dimer, the physiological role of which remains to be elucidated.

GPX3 from Arabidopsis thaliana: cloning, expression, purification, crystallization and preliminary X-ray analysis.

Project description:The Arabidopsis thaliana glutathione peroxidase 3 (GPX3) gene encodes a glutathione peroxidase with roles in H2O2 homeostasis and signalling. The GPX3 gene sequence was cloned into pGEX-6P1 and overexpressed in Escherichia coli. The GPX3 protein was purified to homogeneity in two chromatographic steps. Various lengths of the GPX3 sequence were used to obtain proteins that yielded crystals using vapour-diffusion techniques, but only GPX3ΔN36 (lacking 36 amino acids from the N-terminus) showed a good diffraction pattern. Its crystals diffracted to 2.8 Å resolution and belonged to space group P65, with unit-cell parameters a = b = 98.241, c = 42.057 Å.

Expression, purification, crystallization and preliminary X-ray diffraction analysis of Deg5 from Arabidopsis thaliana.

Project description:Arabidopsis thaliana Deg5 is an ATP-independent serine protease which resides on the luminal side of the thylakoid in chloroplasts. Deg5 and another Deg/HtrA-family protease, Deg8, have a synergistic function in the turnover of the D1 protein of photosystem II (PSII), which is prone to damage arising from high light exposure. An inactive mutant of the protein, Deg5(S266A), was overexpressed in Escherichia coli. After purification and crystallization, crystals that diffracted to 2.6?Å resolution were obtained. The crystals belonged to the monoclinic space group C2, with unit-cell parameters a = 109.1, b = 126.0, c = 83.3?Å, ? = 102.9°, and contained three molecules in the asymmetric unit. The calculated Matthews coefficient and solvent content were 3.0?Å(3)?Da(-1) and 59.0%, respectively.

Overexpression, crystallization and preliminary X-ray crystallographic analysis of release factor eRF1-1 from Arabidopsis thaliana.

Project description:Peptide release factor 1 (RF1) regulates the termination of translation in protein synthesis by recognizing the stop codons. The eukaryotic RF1s (eRF1s) from Arabidopsis thaliana and human have different stop-codon preferences even though they share high sequence similarity. Based on known RF1 structures, it has been suggested that the specificity depends on both the local structure and the domain arrangement, but the lack of a structure of Arabidopsis eRF1 hinders a detailed comparison. To reveal the mechanism of stop-codon recognition and compare it with that of human eRF1, one of the three Arabidopsis eRF1s, AteRF1-1, was studied and a preliminary X-ray crystallographic analysis is reported here. The protein was overexpressed in Escherichia coli and crystallized at room temperature using the vapour-diffusion method. Crystals were grown from 1.6 M lithium sulfate, 0.1 M Tris-HCl pH 8.0, 2%(v/v) PEG 400 and diffracted to 3.77 Å resolution. The data were processed in point group 622, with unit-cell parameters a = b = 136.6, c = 325.7 Å.

Purification, crystallization and preliminary X-ray analysis of PPD6, a PsbP-domain protein from Arabidopsis thaliana.

Project description:The PsbP protein is an extrinsic component of photosystem II that together with PsbO and PsbQ forms the thylakoid lumenal part of the oxygen-evolving complex in higher plants. In addition to PsbP, the thylakoid lumen contains two PsbP-like proteins (PPLs) and six PsbP-domain proteins (PPDs). While the functions of the PsbP-like proteins PPL1 and PPL2 are currently under investigation, the function of the PsbP-domain proteins still remains completely unknown. PPD6 is unique among the PsbP family of proteins in that it contains a conserved disulfide bond which can be reduced in vitro by thioredoxin. The crystal structure determination of the PPD6 protein has been initiated in order to elucidate its function and to gain deeper insights into redox-regulation pathways in the thylakoid lumen. PPD6 has been expressed, purified and crystallized and preliminary X-ray diffraction data have been collected. The crystals belonged to space group P2(1), with unit-cell parameters a = 47.0, b = 64.3, c = 62.0 Å, β = 94.2°, and diffracted to a maximum d-spacing of 2.1 Å.

Cloning, recombinant production, crystallization and preliminary X-ray diffraction analysis of SDF2-like protein from Arabidopsis thaliana.

Project description:The stromal-cell-derived factor 2-like protein of Arabidopsis thaliana (AtSDL) has been shown to be highly up-regulated in response to unfolded protein response (UPR) inducing reagents, suggesting that it plays a crucial role in the plant UPR pathway. AtSDL has been cloned, overexpressed, purified and crystallized using the vapour-diffusion method. Two crystal forms have been obtained under very similar conditions. The needle-shaped crystals did not diffract X-rays, while the other form diffracted to 1.95 A resolution using a synchrotron-radiation source and belonged to the hexagonal space group P6(1), with unit-cell parameters a = b = 96.1, c = 69.3 A.

Recombinant ACHT1 from Arabidopsis thaliana: crystallization and X-ray crystallographic analysis.

Project description:Thioredoxins (Trxs) play important roles in chloroplasts by linking photosynthetic light reactions to a series of plastid functions. They execute their function by regulating the oxidation and reduction of disulfide bonds. ACHT1 (atypical cysteine/histidine-rich Trx1) is a thylakoid-associated thioredoxin-type protein found in the Arabidopsis thaliana chloroplast. Recombinant ACHT1 protein was overexpressed in Escherichia coli, purified and crystallized by the vapour-diffusion method. The crystal diffracted to 1.7 Å resolution and a complete X-ray data set was collected. Preliminary crystallographic analysis suggested that the crystals belonged to space group C2221, with unit-cell parameters a = 102.7, b = 100.6, c = 92.8 Å.
