Thermostable aldolase from Thermus aquaticus.
Data are presented on the purification and properties of the thermostable fructose-1,6-diphosphate aldolase of Thermus aquaticus, a nonsporulating, extreme thermophile. The enzyme shows little activity at temperatures below 60 C and optimal activity at about 95 C. The enzyme was purified 43-fold by diethylaminoethyl cellulose column chromatography and Sephadex G-200 gel filtration. The enzyme i...
متن کاملProperties of Thermus ruber Strains Isolated from Icelandic Hot Springs and DNA:DNA Homology of Thermus ruber and Thermus aquaticus.
Seventeen pink-pigmented strains of the genus Thermus were isolated from samples collected from thermal areas of Iceland. The strains were examined by using phenotypic characterization and DNA:DNA homology and were compared with recognized strains. Visually, the strains could be divided into three groups based on their pigmentation; however, spectroscopic studies of the pigments indicated littl...

15 صفحه اولOligomerization of a MutS mismatch repair protein from Thermus aquaticus.
The MutS DNA mismatch protein recognizes heteroduplex DNAs containing mispaired or unpaired bases. We have examined the oligomerization of a MutS protein from Thermus aquaticus that binds to heteroduplex DNAs at elevated temperatures. Analytical gel filtration, cross-linking of MutS protein with disuccinimidyl suberate, light scattering, and matrix-assisted laser desorption/ionization time-of-f...
متن کاملCharacterization of functionally active subribosomal particles from Thermus aquaticus.
Peptidyl transferase activity of Thermus aquaticus ribosomes is resistant to the removal of a significant number of ribosomal proteins by protease digestion, SDS, and phenol extraction. To define the upper limit for the number of macromolecular components required for peptidyl transferase, particles obtained by extraction of T. aquaticus large ribosomal subunits were isolated and their RNA and ...
