Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of AHP2, a signal transmitter protein from Arabidopsis thaliana.

Project description:Histidine-containing phosphotransfer proteins from Arabidopsis thaliana (AHP1-5) act as intermediates between sensor histidine kinases and response regulators in a signalling system called multi-step phosphorelay (MSP). AHP proteins mediate and potentially integrate various MSP-based signalling pathways (e.g. cytokinin or osmosensing). However, structural information about AHP proteins and their importance in MSP signalling is still lacking. To obtain a deeper insight into the structural basis of AHP-mediated signal transduction, the three-dimensional structure of AHP2 was determined. The AHP2 coding sequence was cloned into pRSET B expression vector, enabling production of AHP2 fused to an N-terminal His tag. AHP2 was expressed in soluble form in Escherichia coli strain BL21 (DE3) pLysS and then purified to homogeneity using metal chelate affinity chromatography and anion-exchange chromatography under reducing conditions. Successful crystallization in a buffer which was optimized for thermal stability yielded crystals that diffracted to 2.5 Å resolution.

SnRK2.6/OST1 from Arabidopsis thaliana: cloning, expression, purification, crystallization and preliminary X-ray analysis of K50N and D160A mutants.

Project description:The SnRK2.6 (SNF1-related kinase 2.6) gene from Arabidopsis thaliana encodes the serine/threonine protein kinase SnRK2.6/OST1 (OPEN STOMATA 1). It plays a central role in the drought-tolerance mechanism. OST1 is in fact the main positive effector in the hydric stress response. The SnRK2.6 gene was cloned into the pGEX4T1 plasmid, mutated and expressed in Escherichia coli, allowing purification to homogeneity in two chromatographic steps. Various OST1 mutants yielded crystals using vapour-diffusion techniques, but only one mutant showed a good diffraction pattern. Its crystals diffracted to 2.8 Å resolution and belonged to space group P222(1), with unit-cell parameters a=77.7, b=99.4, c=108.4 Å. A promising molecular-replacement solution was found using the structure of the kinase domain of the yeast AMP-activated protein kinase SNF1 (PDB entry 3hyh) as the search model.

Cloning, purification, crystallization and preliminary X-ray analysis of the receiver domain of the histidine kinase CKI1 from Arabidopsis thaliana.

Project description:The receiver domain (RD) of a sensor histidine kinase (HK) catalyses the transphosphorylation reaction during the action of HKs in hormonal and abiotic signalling in plants. Crystals of the recombinant RD of the Arabidopsis thaliana HK CYTOKININ-INDEPENDENT1 (CKI1(RD)) have been obtained by the hanging-drop vapour-diffusion method using ammonium sulfate as a precipitant and glycerol as a cryoprotectant. The crystals diffracted to approximately 2.4 A resolution on beamline BW7B of the DORIS-III storage ring. The diffraction improved significantly after the use of a non-aqueous cryoprotectant. Crystals soaked in Paratone-N diffracted to at least 2.0 A resolution on beamline BW7B and their mosaicity decreased more than tenfold. The crystals belonged to space group C222(1), with unit-cell parameters a = 54.46, b = 99.82, c = 79.94 A. Assuming the presence of one molecule of the protein in the asymmetric unit gives a Matthews coefficient V(M) of 2.33 A(3) Da(-1). A molecular-replacement solution has been obtained and structure refinement is in progress.

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.

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.

Cloning, purification, crystallization and preliminary X-ray studies of human ?1-microglobulin.

Project description:?(1)-Microglobulin (?(1)m) is one of the phylogenetically most widespread lipocalins and is distributed in various organs and tissues, including liver, heart, eye, kidney, brain, lung, pancreas and skeletal muscle. ?(1)m has been found to exert multifarious functions, including interacting with IgA, albumin and prothrombin, binding strongly to haem and exhibiting reductase activity. Nevertheless, little structural information is available regarding these functions of ?(1)m. Since determination of three-dimensional structure is a powerful means of functional characterization, X-ray crystallography was used to accomplish this task. Here, the expression, purification, crystallization and preliminary crystallographic analysis of human ?(1)m are reported. The crystal belonged to space group P4(3), with unit-cell parameters a = b = 36.45, c = 112.68 Å, and diffracted to a resolution of 2.0 Å. The crystals are most likely to contain one molecule in the asymmetric unit, with a V(M) value of 1.63 Å(3) Da(-1).

Purification, crystallization and preliminary X-ray crystallographic analysis of Arabidopsis thaliana dynamin-related protein 1A GTPase-GED fusion protein.

Project description:Plant-specific dynamin-related proteins play crucial roles in cell-plate formation, endocytosis or exocytosis, protein sorting to the vacuole and plasma membrane and the division of mitochondria and chloroplasts. In order to determine the crystal structure and thus to obtain a better understanding of the biological functions and mechanisms of dynamin-related proteins in plant cells, the GTPase domain of Arabidopsis thaliana dynamin-related protein 1A (AtDRP1A) fused to its GTPase effector domain (GED) was crystallized in a nucleotide-associated form using polyethylene glycol 3350 as precipitant. The hexagonal crystals (space group P6(1)) had unit-cell parameters a = b = 146.2, c = 204.3 Å, and diffraction data were collected to 3.6 Å resolution using synchrotron radiation. Four molecules, comprising two functional dimers, are assumed per asymmetric unit, corresponding to a Matthews coefficient of 3.9 Å(3) Da(-1) according to the molecular weight of 39 kDa.
