Expression, purification, crystallization and preliminary X-ray crystallographic analysis of the extracellular olfactomedin domain of gliomedin.

ABSTRACT: Gliomedin (GLDN) is one of the essential proteins in the development of the nodes of Ranvier in the vertebrate peripheral nervous system. An olfactomedin (OLF) domain is located at the GLDN extracellular C-terminus and is involved in the accumulation of neuronal plasma membrane voltage-gated sodium channels in the nodes by interacting with neurofascin and NrCAM. No structures of OLF domains have previously been reported. Here, the crystallization of the rat GLDN OLF domain, which was expressed in an insect-cell system, is reported. The crystal diffracted to 1.55?Å resolution and belonged to space group P2?, with unit-cell parameters a=37.5, b=141.7, c=46.0?Å, ?=110.6°, and had two molecules in the asymmetric unit.

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.

Expression, purification, crystallization and preliminary X-ray crystallographic analysis of human ?-galactosidase.

Project description:?-D-Galactosidase (?-Gal) is an exoglycosidase that cleaves ?-galactosides from glycoproteins, sphingolipids and keratan sulfate. This study reports the expression, purification, crystallization and preliminary X-ray crystallographic analysis of human lysosomal ?-Gal. The sitting-drop vapour-diffusion method was used to crystallize ?-Gal in complexes with its product galactose and with the inhibitor 1-deoxygalactonojirimycin. The resulting crystals were isomorphous and belonged to space group P2(1). The crystals of the ?-Gal-galactose and the ?-Gal-inhibitor complexes had unit-cell parameters a = 94.8, b = 116.1, c = 140.3 Å, ? = 92.2° and a = 94.8, b = 116.0, c = 140.3 Å, ? = 92.2°, respectively. Diffraction data were collected to 1.8 Å resolution for both crystals.

Expression, purification, crystallization and preliminary X-ray analysis of the olfactomedin domain from the sea urchin cell-adhesion protein amassin.

Project description:A family of animal proteins is emerging which contain a conserved protein motif known as an olfactomedin (OLF) domain. Novel extracellular protein-protein interactions occur through this domain. The OLF-family member amassin, from the sea urchin Strongylocentrotus purpuratus, has previously been identified to mediate a rapid cell-adhesion event resulting in a large aggregation of coelomocytes, the circulating immune cells. In this work, heterologous expression and purification of the OLF domain from amassin was carried out and initial crystallization trials were performed. A native data set has been collected, extending to 2.7 A under preliminary cryoconditions, using an in-house generator. This work leads the way to the determination of the first structure of an OLF domain.

Cloning, expression, purification, crystallization and preliminary X-ray diffraction crystallographic study of human synaptotagmin 5 C2A domain.

Project description:Synaptotagmin acts as the Ca(2+) sensor for neural and endocrine exocytosis. Synaptotagmin 5 has been demonstrated to play a key role in the acquisition of cathepsin D and the vesicular proton ATPase and in Ca(2+)-dependent insulin exocytosis. The C2 domains modulate the interaction of synaptotagmin with the phospholipid bilayer of the presynaptic terminus and effector proteins such as the SNARE complex. This study reports the cloning, expression in Escherichia coli, purification, crystallization and preliminary X-ray analysis of the C2A domain of human synaptotagmin 5 with an N-terminal His(6) tag. The crystals diffracted to 1.90 Å resolution and belonged to the hexagonal space group P6(5), with unit-cell parameters a = b = 93.97, c = 28.05 Å. A preliminary model of the protein structure has been built and refinement of the model is ongoing.

Purification, crystallization and preliminary X-ray crystallographic analysis of the CIDE-N domain of Fsp27.

Project description:Fsp27, a member of the CIDE protein family which is selectively expressed in adipocytes, has emerged as a novel regulator for unilocular lipid droplet (LD) formation, lipid metabolism, differentiation of adipocytes and insulin sensitivity. An LD is a subcellular compartment that is used by adipocytes for the efficient storage of fats. The CIDE-N domain of Fsp27 functions as a recruitment platform that induces the correct configuration of the Fsp27 CIDE-C domain to facilitate LD fusion. This study reports the high-yield expression of the mouse Fsp27 CIDE-N domain in Escherichia coli; a two-step purification protocol with high efficiency was established and crystallographic analysis was performed. The purity of the recombinant Fsp27 was >95% as assessed by SDS-PAGE. Crystals were obtained at 291 K using 28% polyethylene glycol 4000 as a precipitant. Diffraction data were collected to 1.92 Å resolution and the crystal belonged to space group P6(5), with unit-cell parameters a=b=63.3, c=37.4 Å, α=β=90, γ=120°. The components of the crystal were identified by ion-trap LC/MS/MS spectrometric analysis. The structure has been solved by molecular replacement and refinement is in progress.

Expression, purification, crystallization and preliminary X-ray crystallographic analysis of Zucchini from Drosophila melanogaster.

Project description:PIWI-interacting RNAs (piRNAs) bind PIWI proteins and silence transposons to maintain the genomic integrity of germ cells. Zucchini (Zuc), a phospholipase D superfamily member, is conserved among animals and is implicated in piRNA biogenesis. However, the underlying mechanism by which Zuc participates in piRNA biogenesis remains elusive. Drosophila melanogaster Zuc (DmZuc) was expressed in Escherichia coli, purified and crystallized. X-ray diffraction data were collected to 1.75?Å resolution. The crystal belonged to space group P2(1), with unit-cell parameters a=55.0, b=71.2, c=56.3?Å, ?=107.9°.

Expression, purification, crystallization and preliminary X-ray crystallographic analysis of tomato β-galactosidase 4.

Project description:Plant β-galactosidases play important roles in carbohydrate-reserve mobilization, cell-wall expansion and degradation, and turnover of signalling molecules during ripening. Tomato β-galactosidase 4 (TBG4) not only has β-galactosidase activity but also has exo-β-(1,4)-galactanase activity, and prefers β-(1,4)-galactans longer than pentamers as its substrates; most other β-galactosidases only have the former activity. Recombinant TBG4 protein expressed in the yeast Pichia pastoris was crystallized by the sitting-drop vapour-diffusion method using PEG 10,000 as a precipitant. The crystals belonged to the orthorhombic space group P212121, with unit-parameters a = 92.82, b = 96.30, c = 159.26 Å, and diffracted to 1.65 Å resolution. Calculation of the Matthews coefficient suggested the presence of two monomers per asymmetric unit (VM = 2.2 Å(3) Da(-1)), with a solvent content of 45%.
