Expression, purification and preliminary X-ray diffraction studies of RebC.

ABSTRACT: The flavin-dependent monooxygenase RebC is a key enzyme in the biosynthesis of the indolocarbazole rebeccamycin. The synthesis of rebeccamycin is of great interest as it has been shown to be a natural antitumour agent. The enzyme has been recombinantly expressed in Escherichia coli and purified to homogeneity. Hanging-drop vapour diffusion in combination with microseeding was used to obtain suitable crystals for X-ray diffraction. Data were collected to 2.4 A; the crystals belonged to space group P2(1), with unit-cell parameters a = 63.08, b = 77.85, c = 63.94 A, alpha = gamma = 90, beta = 108.11 degrees .

Cloning, expression, purification and preliminary X-ray diffraction studies of a novel AB? toxin.

Project description:AB? toxins are key virulence factors found in a range of pathogenic bacteria. AB? toxins consist of two components: a pentameric B subunit that targets eukaryotic cells by binding to glycans located on the cell surface and a catalytic A subunit that disrupts host cellular function following internalization. To date, the A subunits of AB? toxins either have RNA-N-glycosidase, ADP-ribosyltransferase or serine protease activity. However, it has been suggested that a novel AB? toxin produced by clinical isolates of Escherichia coli and Citrobacter freundii has an A subunit with metalloproteinase activity. Here, the expression, purification and crystallization of this novel AB? toxin from E. coli (EcxAB) and the collection of X-ray data to 1.9 Å resolution are reported.

Expression, purification and preliminary X-ray diffraction studies of VERNALIZATION1(208-341) from Arabidopsis thaliana.

Project description:VERNALIZATION1 (VRN1) is required in the model plant Arabidopsis thaliana for the epigenetic suppression of the floral repressor FLC by prolonged cold treatment. Stable suppression of FLC accelerates flowering, a physiological process known as vernalization. VRN1 is a 341-residue DNA-binding protein that contains two plant-specific B3 domains (B3a and B3b), a putative nuclear localization sequence (NLS) and two putative PEST domains. VRN1(208-341) includes the second B3 domain and a region upstream that is highly conserved in the VRN1 orthologues of other dicotyledonous plants. VRN1(208-341) was crystallized by the hanging-drop method in 0.05 M sodium acetate pH 6.0 containing 1.0 M NaCl and 18%(w/v) PEG 3350. Preliminary X-ray diffraction data analysis revealed that the VRN1(208-341) crystal diffracted to 2.1 A and belonged to space group C2, with unit-cell parameters a = 105.2, b = 47.9, c = 61.2 A, alpha = 90.0, beta = 115.4, gamma = 90.0 degrees . Assuming that two molecules occupy the asymmetric unit, a Matthews coefficient of 2.05 A(3) Da(-1) and a solvent content of 40.1% were calculated.

Expression, purification, crystallization and preliminary X-ray diffraction studies of phosphoglycerate mutase from Staphylococcus aureus NCTC8325.

Project description:Phosphoglycerate mutase (PGM) is a key enzyme in carbohydrate metabolism. It takes part in both glycolysis and gluconeogenesis. PGM from pathogenic Staphylococcus aureus (NCTC8325) was cloned in pQE30 expression vector overexpressed in Escherichia coli M15 (pREP4) cells and purified to homogeneity. The protein was crystallized from two different conditions, (i) 0.1?M HEPES pH 7.5, 20%(w/v) polyethylene glycol 10,000 and (ii) 0.2?M NaCl, 0.1?M bis-tris pH 6.5, 25%(w/v) polyethylene glycol 3350, at 25°C by the sitting-drop vapour-diffusion method. Crystals grown at pH 7.5 diffracted to 2.5?Å resolution and belonged to the orthorhombic space group P2(1)2(1)2, with unit-cell parameters a = 77.0, b = 86.11, c = 94.07?Å. Crystals from the second condition at pH 6.5 diffracted to 2.00?Å resolution. These crystals belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 73.21, b = 81.75, c = 89.18?Å. X-ray diffraction data have been collected and processed to the maximum resolution to determine the structure of PGM. The structure has been solved by molecular replacement and structure refinement is now in progress.

Expression, purification and preliminary X-ray diffraction studies of the transcriptional factor PyrR from Bacillus halodurans.

Project description:The PyrR transcriptional regulator is widely distributed in bacteria. This RNA-binding protein is involved in the control of genes involved in pyrimidine biosynthesis, in which uridyl and guanyl nucleotides function as effectors. Here, the crystallization and preliminary X-ray diffraction analysis of two crystal forms of Bacillus halodurans PyrR are reported. One of the forms belongs to the monoclinic space group P2(1) with unit-cell parameters a = 59.7, b = 87.4, c = 72.1 A, beta = 104.4 degrees , while the other form belongs to the orthorhombic space group P22(1)2(1) with unit-cell parameters a = 72.7, b = 95.9, c = 177.1 A. Preliminary X-ray diffraction data analysis and molecular-replacement solution revealed the presence of four and six monomers per asymmetric unit; a crystallographic tetramer is formed in both forms.

Purification, crystallization and preliminary X-ray diffraction studies of parakeet (Psittacula krameri) haemoglobin.

Project description:Birds often show efficient oxygen management in order to meet the special demands of their metabolism. However, the structural studies of avian haemoglobins (Hbs) are inadequate for complete understanding of the mechanism involved. Towards this end, purification, crystallization and preliminary X-ray diffraction studies have been carried out for parakeet Hb. Parakeet Hb was crystallized as the met form in low-salt buffered conditions after extracting haemoglobin from crude blood by microcentrifugation and purifying the sample by column chromatography. Good-quality crystals were grown from 10% PEG 3350 and a crystal diffracted to about 2.8 A resolution. Preliminary diffraction data showed that the Hb crystal belonged to the monoclinic system (space group C2), with unit-cell parameters a = 110.68, b = 64.27, c = 56.40 A, beta = 109.35 degrees . Matthews volume analysis indicated that the crystals contained a half-tetramer in the asymmetric unit.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction studies of NAD synthetase from methicillin-resistant Staphylococcus aureus.

Project description:Staphylococcus aureus is an important human and animal pathogen that causes a wide range of infections. The prevalence of multidrug-resistant S. aureus strains in both hospital and community settings makes it imperative to characterize new drug targets to combat S. aureus infections. In this context, enzymes involved in NAD metabolism and synthesis are significant drug targets as NAD is a central player in several cellular processes. NAD synthetase catalyzes the last step in the biosynthesis of nicotinamide adenine dinucleotide, making it a crucial intermediate enzyme linked to the biosynthesis of several amino acids, purine and pyrimidine nucleotides, coenzymes and antibiotics.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction studies of N-acetylneuraminate lyase from methicillin-resistant Staphylococcus aureus.

Project description:The enzyme N-acetylneuraminate lyase (EC 4.1.3.3) is involved in the metabolism of sialic acids. Specifically, the enzyme catalyzes the retro-aldol cleavage of N-acetylneuraminic acid to form N-acetyl-D-mannosamine and pyruvate. Sialic acids comprise a large family of nine-carbon amino sugars, all of which are derived from the parent compound N-acetylneuraminic acid. In recent years, N-acetylneuraminate lyase has received considerable attention from both mechanistic and structural viewpoints and has been recognized as a potential antimicrobial drug target. The N-acetylneuraminate lyase gene was cloned from methicillin-resistant Staphylococcus aureus genomic DNA, and recombinant protein was expressed and purified from Escherichia coli BL21?(DE3). The enzyme crystallized in a number of crystal forms, predominantly from PEG precipitants, with the best crystal diffracting to beyond 1.70?Å resolution in space group P2?. Molecular replacement indicates the presence of eight monomers per asymmetric unit. Understanding the structural biology of N-acetylneuraminate lyase in pathogenic bacteria, such as methicillin-resistant S. aureus, will provide insights for the development of future antimicrobials.
