Organic solutes in hyperthermophilic archaea.
We examined the accumulation of organic solutes under optimum growth conditions in 12 species of thermophilic and hyperthermophilic Archaea belonging to the Crenarchaeota and Euryarchaeota. Pyrobaculum aerophilum, Thermoproteus tenax, Thermoplasma acidophilum, and members of the order Sulfolobales accumulated trehalose. Pyrococcus furiosus accumulated di-myo-inositol-1,1(prm1)(3,3(prm1))-phosph...
متن کاملPhylogenomics of hyperthermophilic Archaea and Bacteria.
The location of hyperthermophilic organisms in the tree of life has been the source of many exciting discussions during the last two decades. It inspired not only novel hypotheses for the early evolution of the organisms, but also the isolation of many new species of Archaea and Bacteria from hot environments, as well as microbial genome sequencing and phylogenomic analyses. In view of the new ...
متن کاملThe question of DNA repair in hyperthermophilic archaea.
Hyperthermophilic archaea grow at temperatures that destabilize the primary structure of DNA and in evolutionary terms they are highly divergent from other well studied microorganisms. These prokaryotes should therefore require DNA damage repair to be unusually effective, and could employ novel mechanisms for this repair. Recent genome sequence analyses and biochemical and genetic assays sugges...
متن کاملAlcohol dehydrogenases from thermophilic and hyperthermophilic archaea and bacteria.
Many studies have been undertaken to characterise alcohol dehydrogenases (ADHs) from thermophiles and hyperthermophiles, mainly to better understand their activities and thermostability. To date, there are 20 thermophilic archaeal and 17 thermophilic bacterial strains known to have ADHs or similar enzymes, including the hypothetical proteins. Some of these thermophiles are found to have multipl...
متن کاملA First Analysis of Metallome Biosignatures of Hyperthermophilic Archaea
To date, no experimental data has been reported for the metallome of hyperthermophilic microorganisms although their metal requirements for growth are known to be unique. Here, experiments were conducted to determine (i) cellular trace metal concentrations of the hyperthermophilic Archaea Methanococcus jannaschii and Pyrococcus furiosus, and (ii) a first estimate of the metallome for these hype...
