A novel species of thermoacidophilic archaeon, Sulfolobus yangmingensis sp. nov.
A novel microbe was isolated from a geothermal vent in Yang-Ming National Park in northern Taiwan. This spherical microbe with mean cell diameter of 1.1 +/- 0.2 microns is a facultatively chemolithoautotrophic archaeon that grows on elemental sulfur and reduced sulfur compounds. The optimal pH and temperature for growth are 4.0 (pH range 2.0-6.0) and 80 degrees C (temperature range 65-95 degree...
متن کاملCleavage of double-stranded RNA by RNase HI from a thermoacidophilic archaeon, Sulfolobus tokodaii 7.
ST0753, the orthologous gene of Type 1 RNase H found in a thermoacidophilic archaeon, Sulfolobus tokodaii, was analyzed. The recombinant ST0753 protein exhibited RNase H activity in both in vivo and in vitro assays. The protein expressed in an RNase H-deficient mutant Escherichia coli strain functioned to suppress the temperature-sensitive phenotype associated with the lack of RNase H. The in v...
متن کاملNutrient utilization and transport in the thermoacidophilic archaeon Sulfolobus shibatae
Department of Biochemistry and Molecular Biology, Royal Free Hospital School of Medicine, University of London, Rowland Hill Street, London NW3 ZPF, UK Growth of the thermoacidophilic archaeon Sulfolobus shibatae was tested on a range of carbon and nitrogen sources. Optimal defined and complex growth media were developed and growth conditions in both shake flask and fermenter cultures were opti...
متن کاملA highly acid-stable and thermostable endo-beta-glucanase from the thermoacidophilic archaeon Sulfolobus solfataricus.
The thermoacidophilic archaeon Sulfolobus solfataricus P2 encodes three hypothetic endo-beta-glucanases, SSO1354, SSO1949 and SSO2534. We cloned and expressed the gene sso1949 encoding the 334 amino acids containing protein SSO1949, which can be classified as a member of glycoside hydrolase family 12. The purified recombinant enzyme hydrolyses carboxymethylcellulose as well as cello-oligomers, ...
متن کاملCopper tolerance of the thermoacidophilic archaeon Sulfolobus metallicus: possible role of polyphosphate metabolism.
It has been postulated that inorganic polyphosphate (polyP) and transport of metal-phosphate complexes could participate in heavy metal tolerance in some bacteria. To study if such a system exists in archaea, the presence of polyP was determined by the electron energy loss spectroscopy (EELS) procedure and quantified by using specific enzymic methods in Sulfolobus acidocaldarius, Sulfolobus met...
