Cloning, expression, purification, crystallization and preliminary X-ray crystallographic study of DHNA synthetase from Geobacillus kaustophilus.

ABSTRACT: The aerobic Gram-positive bacterium Geobacillus kaustophilus is a bacillus species that was isolated from deep-sea sediment from the Mariana Trench. 1,4-Dihydroxy-2-naphthoate (DHNA) synthetase plays a vital role in the biosynthesis of menaquinone (vitamin K(2)) in this bacterium. DHNA synthetase from Geobacillus kaustophilus was crystallized in the orthorhombic space group C222(1), with unit-cell parameters a = 77.01, b = 130.66, c = 131.69 A. The crystal diffracted to a resolution of 2.2 A. Preliminary studies and molecular-replacement calculations reveal the presence of three monomers in the asymmetric unit.

Crystallization and preliminary X-ray crystallographic analysis of L-arabinose isomerase from thermophilic Geobacillus kaustophilus.

Project description:L-arabinose isomerase (AI), which catalyzes the isomerization of L-arabinose to L-ribulose, can also convert D-galactose to D-tagatose, a natural sugar replacer, which is of commercial interest in the food and healthcare industries. Intriguingly, mesophilic and thermophilic AIs showed different substrate preferences and metal requirements in catalysis and different thermostabilities. However, the catalytic mechanism of thermophilic AIs still remains unclear. Therefore, thermophilic Geobacillus kaustophilus AI (GKAI) was overexpressed, purified and crystallized, and a preliminary X-ray diffraction data set was obtained. Diffraction data were collected from a GKAI crystal to 2.70?Å resolution. The crystal belonged to the monoclinic space group C2, with unit-cell parameters a = 224.12, b = 152.95, c = 91.28?Å, ? = 103.61°. The asymmetric unit contained six molecules, with a calculated Matthews coefficient of 2.25?Å(3)?Da(-1) and a solvent content of 45.39%. The three-dimensional structure determination of GKAI is currently in progress by molecular replacement and model building.

Crystallization, characterization and preliminary X-ray crystallographic analysis of GK2848, a putative carbonic anhydrase of Geobacillus kaustophilus.

Project description:GK2848, a hypothetical protein from the thermophilic organism Geobacillus kaustophilus, was cloned and overexpressed in Escherichia coli. The protein was purified to homogeneity using Ni-NTA affinity-column and gel-filtration chromatography. The purified protein was crystallized using the sitting-drop vapour-diffusion method. The crystals diffracted to a resolution of 2.70 Å and belonged to the orthorhombic space group P2(1)2(1)2. GK2848 bears sequence homology to carbonic anhydrases of various bacterial species, indicating that it belongs to the carbonic anhydrase family of proteins. A subsequent carbonic anhydrase activity assay of GK2848 using the Wilbur-Anderson method confirmed its function as a carbonic anhydrase. A preliminary structure solution was obtained by molecular replacement using MOLREP. Mutation and biochemical characterization of the protein are in progress. The structure and functional analysis of GK2848 might provide valuable information on a novel class of carbonic anhydrases, as none of its homologous structures have been characterized.

Crystallization and preliminary crystallographic analysis of the phosphotriesterase-like lactonase from Geobacillus kaustophilus.

Project description:GK1506 from the thermophilic bacterium Geobacillus kaustophilus is a member of the phosphotriesterase-like lactonases, which can catalyze the hydrolysis of a broad range of compounds with different chemical properties. It is of particular interest because of its high thermostability and its dual activity towards organophosphate compounds and some lactones. These properties make GK1506 an attractive target for future enzyme engineering and use in practical applications. In order to resolve the crystal structure of GK1506 and to gain a better understanding of its biological function, recombinant GK1506 was expressed, purified and crystallized using 0.1?M HEPES pH 7.6, 12%(w/v) PEG 8000, 8%(v/v) ethylene glycol at 291?K. A 2.6?Å resolution native data set was collected from a single flash-cooled crystal (100?K) using 10%(v/v) glycerol as a cryoprotectant. These crystals belonged to space group P2(1), with unit-cell parameters a=51.444, b=80.453, c=92.615?Å, ?=99.29°. Two molecules were assumed to be present per asymmetric unit, which gives a Matthews coefficient of 2.7?Å3?Da(-1).

Cloning, expression, purification, crystallization and preliminary X-ray crystallographic analyses of threonyl-tRNA synthetase editing domain from Aeropyrum pernix.

Project description:The proofreading function of aminoacyl-tRNA synthetases is crucial in maintaining the fidelity of protein synthesis. Most archaeal threonyl-tRNA synthetases (ThrRSs) possess a unique proofreading domain unrelated to their eukaryotic/bacterial counterpart. The crystal structure of this domain from the archaeon Pyrococcus abysii in complex with its cognate and noncognate substrate analogues had given insights into its catalytic and discriminatory mechanisms. To probe further into the mechanistic and evolutionary aspects of this domain, work has been extended to another archaeon Aeropyrum pernix. The organism possesses two proteins corresponding to threonyl-tRNA synthetase, i.e. ThrRS1 and ThrRS2, encoded by two different genes, thrS1 and thrS2, respectively. ThrRS1 is responsible for aminoacylation and ThrRS2 for proofreading activity. Here the purification, crystallization and preliminary X-ray crystallographic investigation of the N-terminal proofreading domain of ThrRS2 from A. pernix is reported. The crystals belong to either the P4(1)2(1)2 or P4(3)2(1)2 space group and consist of one monomer per asymmetric unit.

Cloning, expression, purification, crystallization and preliminary X-ray crystallographic study of the putative SAICAR synthetase (PH0239) from Pyrococcus horikoshii OT3.

Project description:The study of proteins involved in de novo biosynthesis of purine nucleotides is central in the development of antibiotics and anticancer drugs. In view of this, a protein from the hyperthermophile Pyrococcus horikoshii OT3 was isolated, purified and crystallized using the microbatch method. Its primary structure was found to be similar to that of SAICAR synthetase, which catalyses the seventh step of de novo purine biosynthesis. A diffraction-quality crystal was obtained using Hampton Research Crystal Screen II condition No. 34, consisting of 0.05 M cadmium sulfate hydrate, 0.1 M HEPES buffer pH 7.5 and 1.0 M sodium acetate trihydrate, with 40%(v/v) 1,4-butanediol as an additive. The crystal belonged to space group P3(1), with unit-cell parameters a = b = 95.62, c = 149.13 A. Assuming the presence of a hexamer in the asymmetric unit resulted in a Matthews coefficient (V(M)) of 2.3 A(3) Da(-1), corresponding to a solvent content of about 46%. A detailed study of this protein will yield insights into structural stability at high temperatures and should be highly relevant to the development of antibiotics and anticancer drugs targeting the biosynthesis of purine nucleotides.

Purification, crystallization and preliminary X-ray diffraction studies of the ATP-binding subunit of an ABC transporter from Geobacillus kaustophilus.

Project description:ATP-binding cassette (ABC) transporters, also known as traffic ATPases, form a large family of integral membrane proteins responsible for the translocation of a variety of chemically diverse substrates across the lipid bilayers of cellular membranes of both prokaryotes and eukaryotes by the hydrolysis of ATP. The ATP-binding subunit of an ABC transporter from Geobacillus kaustophilus, a homodimeric enzyme, was overexpressed in Escherichia coli and purified. Crystals were obtained using the microbatch-under-oil method at 291 K. X-ray diffraction data to 1.6 Å resolution were collected on SPring-8 beamline BL26B1. The crystals belonged to the orthorhombic space group I222, with unit-cell parameters a=54.94, b=78.63, c=112.96 Å. Assuming the presence of a dimer in the asymmetric unit gave a crystal volume per protein weight (VM) of 2.32 Å3 Da(-1) and a solvent content of 47%; this was consistent with the results of a dynamic light-scattering experiment, which showed a dimeric state of the protein in solution. Molecular-replacement trials using the crystal structure of HisP from the Salmonella typhimurium ATP-binding subunit of an ABC transporter as a search model did not provide a satisfactory solution, indicating that the two ATP-binding subunits of ABC transporters have substantially different structures.

Cloning, purification, crystallization and preliminary X-ray crystallographic analysis of MCAT from Staphylococcus aureus.

Project description:Malonyl-CoA:acyl-carrier protein transacylase (MCAT), encoded by the fabd gene, is a key enzyme in type II fatty-acid biosynthesis. It is responsible for transferring the malonyl group from malonyl-CoA to the holo acyl-carrier protein (ACP). Since the type II system differs from the type I system that mammals use, it has received enormous attention as a possible antibiotic target. In particular, only a single isoform of MCAT has been reported and a continuous coupled enzyme assay has been developed. MCAT from Staphylococcus aureus was overexpressed in Escherichia coli and the protein was purified and crystallized. Diffraction data were collected to 1.2 A resolution. The crystals belonged to space group P2(1), with unit-cell parameters a = 41.608, b = 86.717, c = 43.163 A, alpha = gamma = 90, beta = 106.330 degrees . The asymmetric unit contains one SaMCAT molecule.

Cloning, expression, purification, crystallization and preliminary X-ray analysis of Thermus aquaticus succinyl-CoA synthetase.

Project description:Succinyl-CoA synthetase (SCS) is an enzyme of the citric acid cycle and is thus found in most species. To date, there are no structures available of SCS from a thermophilic organism. To investigate how the enzyme adapts to higher temperatures, SCS from Thermus aquaticus was cloned, overexpressed, purified and crystallized. Attempts to crystallize the enzyme were thwarted by proteolysis of the beta-subunit and preferential crystallization of the truncated form. Crystals of full-length SCS were grown after the purification protocol was modified to include frequent additions of protease inhibitors. The resulting crystals, which diffract to 2.35 A resolution, are of the protein in complex with Mn2+-GDP.

Cloning, expression, purification, crystallization and preliminary X-ray crystallographic analysis of bacterioferritin A from Mycobacterium tuberculosis.

Project description:Bacterioferritins (Bfrs) comprise a subfamily of the ferritin superfamily of proteins that play an important role in bacterial iron storage and homeostasis. Bacterioferritins differ from ferritins in that they have additional noncovalently bound haem groups. To assess the physiological role of this subfamily of ferritins, a greater understanding of the structural details of bacterioferritins from various sources is required. The gene encoding bacterioferritin A (BfrA) from Mycobacterium tuberculosis was cloned and expressed in Escherichia coli. The recombinant protein product was purified by affinity chromatography on a Strep-Tactin column and crystallized with sodium chloride as a precipitant at pH 8.0 using the vapour-diffusion technique. The crystals diffracted to 2.1 A resolution and belonged to space group P4(2), with unit-cell parameters a = 123.0, b = 123.0, c = 174.6 A.
