Structure of recombinant prolidase from Thermococcus sibiricus in space group P21221.

ABSTRACT: The crystal structure of recombinant prolidase from Thermococcus sibiricus was determined by X-ray diffraction at a resolution of 2.6?Å and was found to contain a tetramer in the asymmetric unit. A protein crystal grown in microgravity using the counter-diffusion method was used for X-ray studies. The crystal belonged to space group P21221, with unit-cell parameters a = 97.60, b = 123.72, c = 136.52?Å, ? = ? = ? = 90°. The structure was refined to an Rcryst of 22.1% and an Rfree of 29.6%. The structure revealed flexible folding of the N-terminal domain of the protein as well as high variability in the positions of the bound metal ions. The coordinates of the resulting model were deposited in the Protein Data Bank as entry 4rgz.

Influence of intermolecular contacts on the structure of recombinant prolidase from Thermococcus sibiricus.

Project description:Prolidases are peptidases that are specific for dipeptides with proline as the second residue. The structure of recombinant prolidase from the hyperthermophilic archaeon Thermococcus sibiricus (Tsprol) was determined at 2.6?Å resolution. The homodimer of Tsprol is characterized by a complete lack of interactions between the N- and C-terminal domains of the two subunits and hence can be considered to be the most open structure when compared with previously structurally studied prolidases. This structure exists owing to intermolecular coordination bonds between cadmium ions derived from the crystallization solution and histidine residues of a His tag and aspartate and glutamate residues, which link the dimers to each other. This linking leads to the formation of a crystal with a loose packing of protein molecules and low resistance to mechanical influence and temperature increase.

Expression, purification and crystallization of a thermostable short-chain alcohol dehydrogenase from the archaeon Thermococcus sibiricus.

Project description:Alcohol dehydrogenases belong to the oxidoreductase family and play an important role in a broad range of physiological processes. They catalyze the cofactor-dependent reversible oxidation of alcohols to the corresponding aldehydes or ketones. The NADP-dependent short-chain alcohol dehydrogenase TsAdh319 from the thermophilic archaeon Thermococcus sibiricus was overexpressed, purified and crystallized. Crystals were obtained using the hanging-drop vapour-diffusion method using 25%(w/v) polyethylene glycol 3350 pH 7.5 as precipitant. The crystals diffracted to 1.68 A resolution and belonged to space group I222, with unit-cell parameters a = 55.63, b = 83.25, c = 120.75 A.

Expression, purification, crystallization and preliminary crystallographic analysis of a thermostable DNA ligase from the archaeon Thermococcus sibiricus.

Project description:DNA ligases join single-strand breaks in double-stranded DNA by catalyzing the formation of a phosphodiester bond between adjacent 5'-phosphate and 3'-hydroxyl termini. Their function is essential to maintain the integrity of the genome in DNA replication, recombination and repair. A recombinant ATP-dependent DNA ligase from the hyperthermophilic anaerobic archaeon Thermococcus sibiricus was expressed in Escherichia coli and purified. Crystals were grown by vapour diffusion using the hanging-drop method with 17%(w/v) PEG 4000 and 8.5%(v/v) 2-propanol as precipitants. A diffraction experiment was performed with a single crystal, which diffracted X-rays to 3.0 Å resolution. The crystal belonged to space group P2(1)2(1)2(1), with unit-cell parameters a = 58.590, b = 87.540, c = 126.300 Å.

A Novel L-Asparaginase from Hyperthermophilic Archaeon <i>Thermococcus sibiricus</i>: Heterologous Expression and Characterization for Biotechnology Application.

Project description:L-asparaginase (L-ASNase) is a vital enzyme with a broad range of applications in medicine and food industry. Drawbacks of current commercial L-ASNases stimulate the search for better-producing sources of the enzyme, and extremophiles are especially attractive in this view. In this study, a novel L-asparaginase originating from the hyperthermophilic archaeon Thermococcus sibiricus (TsA) was expressed in Escherichia coli, purified and characterized. The enzyme is optimally active at 90 °C and pH 9.0 with a specific activity of 2164 U/mg towards L-asparagine. Kinetic parameters KM and Vmax for the enzyme are 2.8 mM and 1200 µM/min, respectively. TsA is stable in urea solutions 0-6 M and displays no significant changes of the activity in the presence of metal ions Ni2+, Cu2+, Mg2+, Zn2+ and Ca2+ and EDTA added in concentrations 1 and 10 mmol/L except for Fe3+. The enzyme retains 86% of its initial activity after 20 min incubation at 90 °C, which should be enough to reduce acrylamide formation in foods processed at elevated temperatures. TsA displays strong cytotoxic activity toward cancer cell lines K562, A549 and Sk-Br-3, while normal human fibroblasts WI-38 are almost unsensitive to it. The enzyme seems to be a promising candidate for further investigation and biotechnology application.

Cloning, recombinant production and crystallographic structure of Proliferating Cell Nuclear Antigen from radioresistant archaeon Thermococcus gammatolerans.

Project description:Thermococcus gammatolerans is a strictly anaerobic; hyperthermophilicarchaeon belongs to the order Thermococcales in the phylum Euryarchaeota. It was extracted from a hydrothermal vent from the Guaymas Basin (Gulf of California, Mexico). Different studies show that T. gammatolerans is one of the most radioresistant organisms known amongst the archaea. This makes it a unique model to study adaptations to the environment and to study DNA repair mechanisms in an organism able to tolerate harsh conditions. A key protein in these mechanisms is the Proliferation Cell Nuclear Antigen (PCNA). Its function is focused on their ability to slide along the DNA duplex and coordinating the activities of proteins mainly related to DNA edition and processing. Analysis of archaeal proteins have proven to be enormously fruitful because much of the information obtained from them can be extrapolated to eukaryotic systems, and PCNA is no exception. Here we report the cloning, recombinant expression and crystallographic structure of PCNA from T. gammatolerans (TgPCNA).

Metabolic versatility and indigenous origin of the archaeon Thermococcus sibiricus, isolated from a siberian oil reservoir, as revealed by genome analysis.

Project description:Thermococcus species are widely distributed in terrestrial and marine hydrothermal areas, as well as in deep subsurface oil reservoirs. Thermococcus sibiricus is a hyperthermophilic anaerobic archaeon isolated from a well of the never flooded oil-bearing Jurassic horizon of a high-temperature oil reservoir. To obtain insight into the genome of an archaeon inhabiting the oil reservoir, we have determined and annotated the complete 1,845,800-base genome of T. sibiricus. A total of 2,061 protein-coding genes have been identified, 387 of which are absent in other members of the order Thermococcales. Physiological features and genomic data reveal numerous hydrolytic enzymes (e.g., cellulolytic enzymes, agarase, laminarinase, and lipases) and metabolic pathways, support the proposal of the indigenous origin of T. sibiricus in the oil reservoir, and explain its survival over geologic time and its proliferation in this habitat. Indeed, in addition to proteinaceous compounds known previously to be present in oil reservoirs at limiting concentrations, its growth was stimulated by cellulose, agarose, and triacylglycerides, as well as by alkanes. Two polysaccharide degradation loci were probably acquired by T. sibiricus from thermophilic bacteria following lateral gene transfer events. The first, a "saccharolytic gene island" absent in the genomes of other members of the order Thermococcales, contains the complete set of genes responsible for the hydrolysis of cellulose and beta-linked polysaccharides. The second harbors genes for maltose and trehalose degradation. Considering that agarose and laminarin are components of algae, the encoded enzymes and the substrate spectrum of T. sibiricus indicate the ability to metabolize the buried organic matter from the original oceanic sediment.

Structure of glutaminyl cyclase from Drosophila melanogaster in space group I4.

Project description:The structure of ligand-free glutaminyl cyclase (QC) from Drosophila melanogaster (DmQC) has been determined in a novel crystal form. The protein crystallized in space group I4, with unit-cell parameters a = b = 122.3, c = 72.7 Å. The crystal diffracted to a resolution of 2 Å at the home source. The structure was solved by molecular replacement and was refined to an R factor of 0.169. DmQC exhibits a typical α/β-hydrolase fold. The electron density of three monosaccharides could be localized. The accessibility of the active site will facilitate structural studies of novel inhibitor-binding modes.

High-level expression and molecular characterization of a recombinant prolidase from Escherichia coli NovaBlue.

Project description:Long-term use of organophosphorus (OP) compounds has become an increasing global problem and a major threat to sustainability and human health. Prolidase is a proline-specific metallopeptidase that can offer an efficient option for the degradation of OP compounds. In this study, a full-length gene from Escherichia coli NovaBlue encoding a prolidase (EcPepQ) was amplified and cloned into the commercially-available vector pQE-30 to yield pQE-EcPepQ. The overexpressed enzyme was purified from the cell-free extract of isopropyl thio-?-D-galactoside IPTG-induced E. coli M15 (pQE-EcPepQ) cells by nickel-chelate chromatography. The molecular mass of EcPepQ was determined to be about 57 kDa by 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and the result of size-exclusion chromatography demonstrated that the enzyme was mainly present in 25 mM Tris-HCl buffer (pH 8.0) as a dimeric form. The optimal conditions for EcPepQ activity were 60 °C, pH 8.0, and 0.1 mM Mn2+ ion. Kinetic analysis with Ala-Pro as the substrate showed that the K m and k cat values of EcPepQ were 8.8 mM and 926.5 ± 2.0 s-1, respectively. The thermal unfolding of EcPepQ followed a two-state process with one well-defined unfolding transition of 64.2 °C. Analysis of guanidine hydrochloride (GdnHCl)-induced denaturation by tryptophan emission fluorescence spectroscopy revealed that the enzyme had a [GdnHCl]0.5,N-U value of 1.98 M. The purified enzyme also exhibited some degree of tolerance to various water/organic co-solvents. Isopropanol and tetrahydrofuran were very detrimental to the enzymatic activity of EcPepQ; however, other more hydrophilic co-solvents, such as formamide, methanol, and ethylene glycol, were better tolerated. Eventually, the non-negative influence of some co-solvents on both catalytic activity and structural stability of EcPepQ allows to adjust the reaction conditions more suitable for EcPepQ-catalyzed bioprocess.
