Cloning, expression, and molecular characterization of the gene encoding an extremely thermostable [4Fe-4S] ferredoxin from the hyperthermophilic archaeon Pyrococcus furiosus.

چکیده
The gene for ferredoxin from the hyperthermophilic archaeon Pyrococcus furiosus was cloned, sequenced, and expressed in Escherichia coli. The coding region confirmed the determined amino acid sequence. Putative archaeon-type transcriptional regulatory elements were identified. The fdxA gene appears to be an independent transcriptional unit. Recombinant ferredoxin was indistinguishable from the protein purified from P. furiosus in its thermal stability and in the potentiometric and spectroscopic properties of its [4Fe-4S] cluster.

WOR5, a novel tungsten-containing aldehyde oxidoreductase from Pyrococcus furiosus with a broad substrate Specificity.
WOR5 is the fifth and last member of the family of tungsten-containing oxidoreductases purified from the hyperthermophilic archaeon Pyrococcus furiosus. It is a homodimeric protein (subunit, 65 kDa) that contains one [4Fe-4S] cluster and one tungstobispterin cofactor per subunit. It has a broad substrate specificity with a high affinity for several substituted and nonsubstituted aliphatic and a...
متن کاملThe ferredoxin-dependent conversion of glyceraldehyde-3-phosphate in the hyperthermophilic archaeon Pyrococcus furiosus represents a novel site of glycolytic regulation.
The fermentative conversion of glucose in anaerobic hyperthermophilic Archaea is a variant of the classical Embden-Meyerhof pathway found in Bacteria and Eukarya. A major difference of the archaeal glycolytic pathway concerns the conversion of glyceraldehyde-3-phosphate. In the hyperthermophilic archaeon Pyrococcus furiosus, this reaction is catalyzed by an unique enzyme, glyceraldehyde-3-phosp...

The hyperthermophilic archaea Pyrococcus furiosus and Thermococcus litoralis contain the tungstoenzymes aldehyde ferredoxin oxidoreductase, a homodimer, and formaldehyde ferredoxin oxidoreductase, a homotetramer. herein we report the cloning and sequencing of the P. furiosus gene aor (605 residues; M(r), 66,630) and the T. litoralis gene for (621 residues; M(r), 68,941).
متن کاملBiochemical adaptations of two sugar kinases from the hyperthermophilic archaeon Pyrococcus furiosus.
The hyperthermophilic archaeon Pyrococcus furiosus possesses a modified Embden-Meyerhof pathway, including an unusual ADP-dependent glucokinase (ADP-GLK) and an ADP-dependent phosphofructokinase. In the present study, we report the characterization of a P. furiosus galactokinase (GALK) and its comparison with the P. furiosus ADP-GLK. The pyrococcal genes encoding the ADP-GLK and GALK were funct...

The structural gene pfTRM1 (GenBank accession no. AF051912), encoding tRNA(guanine-26, N 2- N 2) methyltransferase (EC 2.1.1.32) of the strictly anaerobic hyperthermophilic archaeon Pyrococcus furiosus, has been identified by sequence similarity to the TRM1 gene of Saccharomyces cerevisiae (YDR120c). The pfTRM1 gene in a 3.0 kb restriction DNA fragment of P.furiosus genomic DNA has been cloned ...
