Purification, crystallization and preliminary X-ray diffraction studies of Rab11 in complex with Rab11-FIP2.

ABSTRACT: The small GTPase Rab11 regulates the recycling of endosomes back to the plasma membrane. In its active GTP-bound form, Rab11 binds a novel set of effectors termed the Rab11 family of interacting proteins (Rab11-FIPs) which contain a conserved C-terminal Rab-binding domain (RBD) of unknown structure. Here, a complex of Rab11 with the RBD of Rab11-FIP2 has been purified and crystallized in the trigonal space group P3(1)21, with unit-cell parameters a = 64.99, b = 64.99, c = 112.59 angstroms. Static light-scattering analyses of the molecular weight of the complex in solution are consistent with two copies of Rab11 and two copies of Rab11-FIP2 in the complex.

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.

Purification, crystallization and preliminary X-ray diffraction of human S100A15.

Project description:Human S100A15 is a novel member of the S100 family of EF-hand calcium-binding proteins and was recently identified in psoriasis, where it is significantly upregulated in lesional skin. The protein is implicated as an effector in calcium-mediated signal transduction pathways. Although its biological function is unclear, the association of the 11.2 kDa S100A15 with psoriasis suggests that it contributes to the pathogenesis of the disease and could provide a molecular target for therapy. To provide insight into the function of S100A15, the protein was crystallized to visualize its structure and to further the understanding of how the many similar calcium-binding mediator proteins in the cell distinguish their cognate target molecules. The S100A15 protein has been cloned, expressed and purified to homogeneity and produced two crystal forms. Crystals of form I are triclinic, with unit-cell parameters a = 33.5, b = 44.3, c = 44.8 angstroms, alpha = 71.2, beta = 68.1, gamma = 67.8 degrees and an estimated two molecules in the asymmetric unit, and diffract to 1.7 angstroms resolution. Crystals of form II are monoclinic, with unit-cell parameters a = 82.1, b = 33.6, c = 52.2 angstroms, beta = 128.2 degrees and an estimated one molecule in the asymmetric unit, and diffract to 2.0 angstroms resolution. This structural analysis of the human S100A15 will further aid in the phylogenic comparison between the other members of the S100 protein family, especially the highly homologous paralog S100A7.

Purification, crystallization, preliminary X-ray diffraction and molecular-replacement studies of catfish (Clarias magur) haemoglobin.

Project description:Haemoglobin is an interesting physiologically significant protein composed of specific functional prosthetic haem and globin moieties. In recent decades, there has been substantial interest in attempting to understand the structural basis and functional diversity of fish haemoglobins (Hbs). Towards this end, purification, crystallization, preliminary X-ray diffraction and molecular-replacement studies have been carried out on Clarias magur Hb. Crystals were grown by the hanging-drop vapour-diffusion method using PEG 2000 and NaCl as precipitants. The crystals belonged to the primitive monoclinic system P2, with unit-cell parameters a=98.35, b=56.63, c=112.88?Å, ?=100.22°; a complete data set was collected to a resolution of 2.4?Å. The Matthews coefficient of 2.42?Å3?Da(-1) for the crystal indicated the presence of two ?2?2 tetramers in the asymmetric unit.

Purification, crystallization and preliminary X-ray diffraction studies on avian haemoglobin from pigeon (Columba livia).

Project description:Haemoglobin is a physiologically significant metalloprotein that is involved in the exchange of gases for sustaining life. The respiratory system of birds is unique and complex compared with that of mammals. Many investigations of avian haemoglobins have revealed the presence of inositol pentaphosphate (IP5), a principal allosteric effector that is involved in regulation of their function. Structural investigations of avian haemoglobins are presently not adequate to explain their function. Efforts have been made in this direction in order to understand the oxygen-binding affinity involved in adapting to hypoxia in avian haemoglobins. Fresh whole blood was collected from pigeon (Columba livia) and purified using a DEAE cellulose anion-exchange chromatographic column. Crystallization of pigeon haemoglobin was accomplished using the hanging-drop vapour-diffusion method using PEG 3350 as a precipitant in 50 mM sodium acetate buffer pH 5.5 with 1 M NaCl. Data collection was carried out using a MAR345 image-plate detector system. The crystals diffracted to 2 A resolution. Pigeon haemoglobin crystallizes in a triclinic space group, with two whole biological molecules in the asymmetric unit and with unit-cell parameters a = 55.005, b = 65.528, c = 104.370 A, alpha = 78.742, beta = 89.819, gamma = 65.320 degrees .

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.

Cloning, purification, crystallization and preliminary X-ray diffraction studies of Escherichia coli PapD-like protein (EcpD).

Project description:Many Gram-negative bacteria are characterized by hair-like proteinaceous appendages on their surface known as fimbriae. In uropathogenic strains of Escherichia coli, fimbriae mediate attachment by binding to receptors on the host cell, often contributing to virulence and disease. E. coli PapD-like protein (EcpD) is a periplasmic chaperone that plays an important role in the proper folding and guiding of Yad fimbrial proteins to the outer membrane usher protein in a process known as pilus biogenesis. EcpD is essential for pilus biogenesis in uropathogenic E. coli and plays an important role in virulence. In the present study, EcpD was cloned, overexpressed, purified and crystallized by the hanging-drop vapour-diffusion method. The crystals diffracted to 1.67 Å resolution and belonged to the orthorhombic space group C222(1), with unit-cell parameters a = 100.3, b = 127.6, c = 45.9 Å. There was a single molecule in the asymmetric unit and the corresponding Matthews coefficient was calculated to be 3.02 Å(3) Da(-1), with 59% solvent content. Initial phases were determined by molecular replacement.
