Characterization of an aminoacylase from the hyperthermophilic archaeon Pyrococcus furiosus.
Aminoacylase was identified in cell extracts of the hyperthermophilic archaeon Pyrococcus furiosus by its ability to hydrolyze N-acetyl-L-methionine and was purified by multistep chromatography. The enzyme is a homotetramer (42.06 kDa per subunit) and, as purified, contains 1.0 +/- 0.48 g-atoms of zinc per subunit. Treatment of the purified enzyme with EDTA resulted in complete loss of activity...
متن کاملTranscriptional and biochemical analysis of starch metabolism in the hyperthermophilic archaeon Pyrococcus furiosus.
Pyrococcus furiosus utilizes starch and its degradation products, such as maltose, as primary carbon sources, but the pathways by which these alpha-glucans are processed have yet to be defined. For example, its genome contains genes proposed to encode five amylolytic enzymes (including a cyclodextrin glucanotransferase [CGTase] and amylopullulanase), as well as two transporters for maltose and ...
متن کاملCharacterization of the reverse gyrase from the hyperthermophilic archaeon Pyrococcus furiosus.
The reverse gyrase gene rgy from the hyperthermophilic archaeon Pyrococcus furiosus was cloned and sequenced. The gene is 3,642 bp (1,214 amino acids) in length. The deduced amino acid sequence has relatively high similarity to the sequences of the Methanococcus jannaschii reverse gyrase (48% overall identity), the Sulfolobus acidocaldarius reverse gyrase (41% identity), and the Methanopynrus k...
متن کاملDefining genes in the genome of the hyperthermophilic archaeon Pyrococcus furiosus: implications for all microbial genomes.
The original genome annotation of the hyperthermophilic archaeon Pyrococcus furiosus contained 2,065 open reading frames (ORFs). The genome was subsequently automatically annotated in two public databases by the Institute for Genomic Research (TIGR) and the National Center for Biotechnology Information (NCBI). Remarkably, more than 500 of the originally annotated ORFs differ in size in the two ...
متن کاملMutational Analyses of the Enzymes Involved in the Metabolism of Hydrogen by the Hyperthermophilic Archaeon Pyrococcus furiosus
Pyrococcus furiosus grows optimally near 100°C by fermenting carbohydrates to produce hydrogen (H(2)) or, if elemental sulfur (S(0)) is present, hydrogen sulfide instead. It contains two cytoplasmic hydrogenases, SHI and SHII, that use NADP(H) as an electron carrier and a membrane-bound hydrogenase (MBH) that utilizes the redox protein ferredoxin. We previously constructed deletion strains lack...
