Crystallization and preliminary X-ray crystallographic studies of swine CD8?.

ABSTRACT: CD8?? homodimers or CD8?? heterodimers form on the T-cell surface, where they are essential as co-receptors for MHC class I molecules in activation of the CTL response. To date, swine have been found to show the highest percentage of lymphocytes with surface expression of CD8?. Crystallographic analysis of swine CD8? (sCD8?) to 1.8?Å resolution revealed that the crystals belonged to space group P3(2)21, with unit-cell parameters a = 80.97, b = 80.97, c = 95.19?Å. The Matthews coefficient and the solvent content were calculated to be 3.23?Å(3)?Da(-1) and 61.89%, respectively. These results may aid further structural and functional analyses of sCD8?.

CD8αα homodimers or CD8αβ heterodimers form on the T-cell surface, where they are essential as co-receptors for MHC class I molecules in activation of the CTL response. To date, swine have been found to show the highest percentage of lymphocytes with surface expression of CD8α. Crystallographic analysis of swine CD8α (sCD8α) to 1.8 Å resolution revealed that the crystals belonged to space group P3(2)21, with unit-cell parameters a = 80.97, b = 80.97, c = 95.19 Å.

Complex assembly, crystallization and preliminary X-ray crystallographic studies of the swine major histocompatibility complex molecule SLA-1*1502.

Project description:In order to illustrate the structure of the swine MHC class I (SLA-I) molecule and to evaluate the cytotoxic T lymphocyte (CTL) response against porcine reproductive and respiratory syndrome virus (PRRSV), the ternary complex of the SLA-I molecule termed SLA-1*1502 with ?(2)-microglobulin and the CTL epitope TMPPGFELY (PRRSV-NSP9(TY9)) derived from PRRSV nonstructural protein 9 (residues 198-206) was assembled and crystallized. The crystal diffracted X-rays to 2.2 Å resolution and belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 66.1, b = 74.1, c = 98.6 Å; it contained one molecule in the asymmetric unit. The Matthews coefficient and the solvent content were calculated to be 2.74 Å(3) Da(-1) and 55.17%, respectively. The results will be helpful in obtaining insight into the structural basis of the presentation of viral epitopes by SLA-I.

Purification, crystallization and preliminary X-ray crystallographic studies of Drep2 CIDE domain.

Project description:Drep2 is a novel nuclease from the fruit fly that might have a similar function in apoptosis to DFF40 and DFF45, which are primary players in apoptotic DNA fragmentation. Drep2 contains a conserved CIDE domain of ∼90 amino-acid residues that is involved in protein-protein interaction. In this study, the Drep2 CIDE domain was purified and crystallized by the hanging-drop vapour-diffusion method. X-ray diffraction data were then collected to a resolution of 2.3 Å. The crystals were found to belong to the orthorhombic space group P212121, with unit-cell parameters a = 50.28, b = 88.70, c = 113.37 Å.

Crystallization and preliminary X-ray crystallographic studies of pig heart carbonyl reductase.

Project description:Pig heart carbonyl reductase (PHCR), which belongs to the short-chain dehydrogenase/reductase (SDR) family, has been crystallized by the hanging-drop vapour-diffusion method. Two crystal forms (I and II) have been obtained in the presence of NADPH. Form I crystals belong to the tetragonal space group P4(2), with unit-cell parameters a = b = 109.61, c = 94.31 A, and diffract to 1.5 A resolution. Form II crystals belong to the tetragonal space group P4(1)2(1)2, with unit-cell parameters a = b = 120.10, c = 147.00 A, and diffract to 2.2 A resolution. Both crystal forms are suitable for X-ray structure analysis at high resolution.

Purification, crystallization and preliminary X-ray crystallographic studies of Rv3899c from Mycobacterium tuberculosis.

Project description:Rv3899c, a hypothetical protein from Mycobacterium tuberculosis that is conserved within the mycobacteria, is predicted to be secreted and has been found in culture filtrates. Here, Rv3899c has been cloned, expressed in Escherichia coli and purified using standard chromatographic techniques. The hanging-drop vapour-diffusion method with PEG 3350 as a precipitant was used to crystallize the protein. N-terminal sequencing results showed that the amino-acid sequence of the crystallized protein began with GATAG, indicating that it is a fragment containing residues 184-410 of Rv3899c. Rv3899c184-410 crystals exhibited the symmetry of space group P2(1)2(1)2(1), with unit-cell parameters a=49.88, b=54.72, c=75.52?Å, ?=?=?=90°, and diffracted to a resolution of 1.90?Å.

Purification, crystallization and preliminary x-ray crystallographic studies of RAIDD Death-Domain (DD).

Project description:Caspase-2 activation by formation of PIDDosome is critical for genotoxic stress induced apoptosis. PIDDosome is composed of three proteins, RAIDD, PIDD, and Caspase-2. RAIDD is an adaptor protein containing an N-terminal Caspase-Recruiting-Domain (CARD) and a C-terminal Death-Domain (DD). Its interactions with Caspase-2 and PIDD through CARD and DD respectively and formation of PIDDosome are important for the activation of Caspase-2. RAIDD DD cloned into pET26b vector was expressed in E. coli cells and purified by nickel affinity chromatography and gel filtration. Although it has been known that the most DDs are not soluble in physiological condition, RAIDD DD was soluble and interacts tightly with PIDD DD in physiological condition. The purified RAIDD DD alone has been crystallized. Crystals are trigonal and belong to space group P3(1)21 (or its enantiomorph P3(2)21) with unit-cell parameters a = 56.3, b = 56.3, c = 64.9 A and gamma = 120 degrees . The crystals were obtained at room temperature and diffracted to 2.0 A resolution.

Crystallization and preliminary X-ray crystallographic studies of the PYD domain of human NALP3.

Project description:The NALP3 inflammasome is a macromolecular complex that is responsible for the innate immune response against infection by bacterial and viral pathogens. The NALP3 inflammasome is composed of three protein components: NALP3, ASC and caspase 1. Interaction between NALP3 and ASC via PYD domains is critical for the assembly of the NALP3 inflammasome. In this study, human NALP3 PYD, corresponding to amino acids 3-110, was overexpressed in Escherichia coli using engineered C-terminal His tags. NALP3 PYD was then purified to homogeneity and crystallized at 293 K. Finally, X-ray diffraction data were collected to a resolution of 1.7 Å from a crystal belonging to the primitive monoclinic space group P2(1), with unit-cell parameters a = 42.03, b = 60.14, c = 51.61 Å, ? = 107.40°.
