Purification, crystallization and preliminary X-ray crystallographic analysis of the human heat-shock protein 40 Hdj1 and its C-terminal peptide-binding domain.

ABSTRACT: Hsp40 is a co-chaperone of Hsp70 that correctly folds polypeptides that exist in non-native forms. The C-terminal peptide-binding domain (CTD) of the human Hsp40 Hdj1 has been purified and crystallized. In the presence of the C-terminal octapeptide of human Hsp70, four types of crystals, types I-B, II, III and IV, were grown and diffracted to 1.85, 2.51, 2.10 and 2.80?Å resolution, respectively. In the absence of the octapeptide, type I-A crystals of the CTD were grown that diffracted to 2.05?Å resolution. The full-length Hdj1 was also purified and crystallized (type V crystals); the crystal diffracted to 3.90?Å 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.

Purification, crystallization and preliminary X-ray crystallographic analysis of squid heavy meromyosin.

Project description:All muscle-based movement is dependent upon carefully choreographed interactions between the two major muscle components, myosin and actin. Regulation of vertebrate smooth and molluscan muscle contraction is myosin based (both are in the myosin II class), and requires the double-headed form of myosin. Removal of Ca2+ from these muscles promotes a relatively compact conformation of the myosin dimer, which inhibits its interaction with actin. Although atomic structures of single myosin heads are available, the structure of any double-headed portion of myosin, including the ∼375 kDa heavy meromyosin (HMM), has only been visualized at low (∼20 Å) resolution by electron microscopy. Here, the growth of three-dimensional crystals of HMM with near-atomic resolution (up to ∼5 Å) and their X-ray diffraction are reported for the first time. These crystals were grown in off-state conditions, that is in the absence of Ca2+ and the presence of nucleotide analogs, using HMM from the funnel retractor muscle of squid. In addition to the crystallization conditions, the techniques used to isolate and purify this HMM are also described. Efforts at phasing and improving the resolution of the data in order to determine the structure are ongoing.

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.

Purification, crystallization and preliminary X-ray crystallographic analysis of PBP4 from Listeria monocytogenes.

Project description:Penicillin-binding proteins (PBPs), which catalyze peptidoglycan synthesis, have been extensively studied as a well established target of antimicrobial agents, including ?-lactam derivatives. However, remarkable resistance to ?-lactams has developed among pathogenic bacteria since the clinical use of penicillin began. Recently, the glycosyltransferase (GT) domain of class A PBPs has been proposed as an attractive target for antibiotic development as moenomycin-bound GT-domain structures have been determined. In this study, a class A PBP4 from Listeria monocytogenes was overexpressed, purified and crystallized using the hanging-drop vapour-diffusion method. Diffraction data were collected to 2.1 Å resolution using synchrotron radiation. The crystal belonged to the primitive orthorhombic space group P2(1)2(1)2, with unit-cell parameters a = 84.6, b = 127.8, c = 54.9 Å. The structural information will contribute to the further development of moenomycin-derived antibiotics possessing broad-spectrum activity.

Purification, crystallization and preliminary X-ray crystallographic analysis of TssL from Vibrio cholerae.

Project description:The type VI secretion system (T6SS) is a macromolecular complex that is conserved in Gram-negative bacteria. The T6SS secretes effector proteins into recipient cells in a contact-dependent manner in order to accomplish cooperative and competitive interactions with the cells. Although the composition and mechanism of the T6SS have been intensively investigated across many Gram-negative bacteria, to date structural information on T6SS components from the important pathogen Vibrio cholerae has been rare. Here, the cloning, purification, crystallization and preliminary X-ray crystallographic analysis of the cytoplasmic domain of TssL, an inner membrane protein of the T6SS, from V. cholerae are reported. Diffraction data were collected to 1.5?Å resolution using synchrotron radiation. The crystal belonged to the hexagonal space group P61, with unit-cell parameters a = 78.4, b = 78.4, c = 49.5?Å. The successful structural characterization of TssL from V. cholerae will contribute to understanding the role of the membrane-associated subunits of the T6SS in more detail.

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.
