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 کاملHyperthermophilic dehydrogenase enzymes.
Archaeal dehydrogenases are often found to be of a specific class of dehydrogenase which has low sequence identity to the equivalent bacterial and eukaryotic counterparts. This paper focuses on two different types of hyperthermophilic dehydrogenase enzyme that have been cloned and over-expressed in Escherichia coli. The crystallographic structures of the apo form of GAPDH (glyceraldehyde-3-phos...
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...
متن کاملPCR-based identification of hyperthermophilic archaea of the family Thermococcaceae.
A method for rapid detection and identification of hyperthermophilic archaea of the family Thermococcaceae based on PCR amplification of 16S rRNA gene fragments with primers TcPc 173F (5'-TCCCCCATAGGYCTGRGGTACTGGAAGGTC-3') and TcPc 589R (5'-GCCGTGRGATTTCGCCAGGGACTTACGGGC-3') was developed and used for identification of new isolates.
