The distribution of enzymes involved in oxidative Stickland reactions among archaea was estimated using BLAST searches (BLOSUM62) with the protein sequences of acetate-CoA ligase (EC 6.2.1.13, ACS), ketoisovalerate oxidoreductase (EC 1.2.7.7, BC-OR) and indolepyruvate oxdoreductase (EC 1.2.7.8, AR-OR) from Pyrococcus furiosus (Pfu) and Sulfolobus solfataricus (Sso) against all archaea. Positive results are indicated by a '+' (homologue found, e-value < 1e-20) and negative results by a '-' (no ...

The calculation of amino acid uptake rates for cells of Sulfolobus solfataricus P2 grown on caseinhydrolysate was performed based on the relative consumption of individual amino acids from the growth medium and the previously published absolute concentration of amino acids in the used growth medium.

Protein, RNA and DNA content during the logarithmic growth phase were investigated in this study. The values represent the average of at least three independent experiments. Errors represent the standard deviation between the experiments.
