Crystallization and preliminary X-ray diffraction analysis of the invertase from Saccharomyces cerevisiae.

ABSTRACT: Saccharomyces cerevisiae invertase (ScInv) is an enzyme encoded by the SUC2 gene that releases ?-fructose from the nonreducing termini of various ?-D-fructofuranoside substrates. Its ability to produce 6-kestose by transglycosylation makes this enzyme an interesting research target for applications in industrial biotechnology. The native enzyme, which presents a high degree of oligomerization, was crystallized by vapour-diffusion methods. The crystals belonged to space group P3(1)21, with unit-cell parameters a=268.6, b=268.6, c=224.4?Å. The crystals diffracted to 3.3?Å resolution and gave complete data sets using a synchrotron X-ray source.

Saccharomyces cerevisiae invertase (ScInv) is an enzyme encoded by the SUC2 gene that releases β-fructose from the nonreducing termini of various β-D-fructofuranoside substrates. Its ability to produce 6-kestose by transglycosylation makes this enzyme an interesting research target for applications in industrial biotechnology. The native enzyme, which presents a high degree of oligomerization, was crystallized by vapour-diffusion methods. The crystals belonged to space group P3(1)21, with unit-c ...[more]

Crystallization and preliminary X-ray diffraction analysis of motif N from Saccharomyces cerevisiae Dbf4.

Project description:The Cdc7-Dbf4 complex plays an instrumental role in the initiation of DNA replication and is a target of replication-checkpoint responses in Saccharomyces cerevisiae. Cdc7 is a conserved serine/threonine kinase whose activity depends on association with its regulatory subunit, Dbf4. A conserved sequence near the N-terminus of Dbf4 (motif N) is necessary for the interaction of Cdc7-Dbf4 with the checkpoint kinase Rad53. To understand the role of the Cdc7-Dbf4 complex in checkpoint responses, a fragment of Saccharomyces cerevisiae Dbf4 encompassing motif N was isolated, overproduced and crystallized. A complete native data set was collected at 100 K from crystals that diffracted X-rays to 2.75 A resolution and structure determination is currently under way.

Crystallization and preliminary X-ray diffraction data of alpha-galactosidase from Saccharomyces cerevisiae.

Project description:Saccharomyces cerevisiae alpha-galactosidase is a highly glycosylated extracellular protein that catalyzes the hydrolysis of alpha-galactosidic linkages in various glucids. Its enzymatic activity is of interest in many food-related industries and has biotechnological applications. Glycosylated and in vitro deglycosylated protein samples were both assayed for crystallization, but only the latter gave good-quality crystals that were suitable for X-ray crystallography. The crystals belonged to space group P42(1)2, with unit-cell parameters a = b = 101.24, c = 111.52 A. A complete diffraction data set was collected to 1.95 A resolution using a synchrotron source.

Expression, purification, crystallization and preliminary X-ray diffraction analysis of mitochondrial thioredoxin Trx3 from Saccharomyces cerevisiae.

Project description:There are three thioredoxin isoforms in the yeast Saccharomyces cerevisiae: two cytosolic/nuclear thioredoxins, Trx1 and Trx2, and one mitochondrial thioredoxin, Trx3. In the present work, S. cerevisiae Trx3 overexpressed in Escherichia coli was purified and crystallized. The Trx3 crystals were obtained by the hanging-drop vapour-diffusion method. A data set diffracting to 2.0 A resolution was collected from a single crystal. The crystal belongs to space group P3(1), with unit-cell parameters a = b = 49.57, c = 94.55 A, alpha = beta = 90, gamma = 120 degrees. The asymmetric unit is assumed to contain two subunits of Trx3, with a V(M) value of 2.62 A(3) Da(-1) and a solvent content of 53%.

Crystallization and preliminary X-ray analysis of isomaltase from Saccharomyces cerevisiae.

Project description:Isomaltase from Saccharomyces cerevisiae is an oligo-1,6-glucosidase that preferentially hydrolyzes isomaltose, with little activity towards isomaltotriose or longer oligosaccharides. An amino-acid sequence analysis of the isomaltase revealed that it belongs to glucoside hydrolase family 13. Recombinant isomaltase was purified and crystallized by the hanging-drop vapour-diffusion method with PEG 3350 as the precipitant. The crystals belonged to space group C2, with unit-cell parameters a = 95.67, b = 115.42, c = 61.77 A, beta = 91.17 degrees . X-ray diffraction data were collected to 1.35 A resolution from a single crystal on a synchrotron-radiation source.

Crystallization and preliminary X-ray diffraction analysis of the beta subunit Yke2 of the Gim complex from Saccharomyces cerevisiae.

Project description:The Gim complex (GimC) from Saccharomyces cerevisiae is a heterohexameric protein complex, also known as prefoldin (PFD), which binds and stabilizes unfolded target polypeptides and subsequently delivers them to chaperonins for completion of folding. In this study, the crystallization and preliminary X-ray analysis of one of the beta subunits of the Gim complex (Yke2) from S. cerevisiae are described. The purified protein was crystallized by the vapour-diffusion method, producing two types of crystals that belonged to the orthorhombic space group C222 or the primitive monoclinic space group P2(1). The unit-cell parameters for the C-centred orthorhombic crystal were a = 48.2, b = 168.86, c = 131.81 A and the unit-cell parameters for the primitive monoclinic crystal were a = 47.83, b = 134.90, c = 81.50 A, beta = 100.71 degrees . The Yke2 crystals diffracted to 4.2 and 3.1 A resolution, respectively, on a rotating-anode generator under cryoconditions. This is the first report concerning the crystallization of a beta subunit of a eukaryotic prefoldin.

Crystallization and preliminary X-ray diffraction crystallographic study of tRNA m(1)A58 methyltransferase from Saccharomyces cerevisiae.

Project description:In Saccharomyces cerevisiae, TRM6 and TRM61 compose a tRNA methyltransferase which catalyzes the methylation of the N1 of adenine at position 58 in tRNAs, especially initiator methionine tRNA. TRM61 is the subunit that binds S-adenosyl-L-methionine and both subunits contribute to target tRNA binding. In order to elucidate the catalytic mechanism of TRM6-TRM61 and the mode of interaction between the two subunits, expression, purification, crystallization and X-ray diffraction analysis of the TRM6-TRM61 complex were performed in this study. The crystals diffracted to 2.80 Å resolution and belonged to the trigonal space group P3(1)21 or P3(2)21, with unit-cell parameters a = b = 139.14, c = 101.62 Å.

Purification, crystallization and preliminary X-ray analysis of glutathione peroxidase Gpx3 from Saccharomyces cerevisiae.

Project description:The glutathione peroxidase Gpx3 from the yeast Saccharomyces cerevisiae has been overexpressed, purified and crystallized. Both gel-filtration and dynamic light-scattering (DLS) results indicate that Gpx3 is a monomer in solution at a concentration of about 2 mg ml(-1), whereas glutathione peroxidases are normally tetrameric or dimeric. X-ray diffraction data from a single crystal of Gpx3 have been collected to 2.6 A resolution. The crystals are triclinic and belong to space group P1, with unit-cell parameters a = 38.187, b = 43.372, c = 56.870 A, alpha = 71.405, beta = 73.376, gamma = 89.633 degrees. There are two Gpx3 monomers in a crystallographic asymmetric unit. Preliminary analyses show that the yeast Gpx3 is quite different from those of mammals.

Crystallization and preliminary X-ray crystallographic analysis of sterol transcription factor Upc2 from Saccharomyces cerevisiae.

Project description:Upc2, a zinc-cluster transcription factor, is a regulator of ergosterol biosynthesis in yeast. In response to sterol levels, the transcriptional activity of Upc2 is controlled by the C-terminal domain. In this study, the C-terminal regulatory domain of Upc2 from Saccharomyces cerevisiae was purified and crystallized by the vapour-diffusion method. To improve the diffraction quality of Upc2 crystals, a Upc2 fusion protein in which 11 residues of the variable loop (residues 715-725) were replaced by T4 lysozymes in Upc2 (Upc2-T4L) was engineered. The Upc2-T4L crystals diffracted to 2.9 Å resolution using synchrotron radiation. The crystal was trigonal, belonging to space group P3(2) with unit-cell parameters a = 67.2, b = 67.2, c = 257.5 Å. The Matthews coefficient was determined to be 3.41 Å(3) Da(-1) with two molecules in the asymmetric unit. Initial attempts to solve the structure by the single-anomalous dispersion technique using selenomethionine were successful.
