Abstract Polypeptide synthesis at high temperature directed by single strand DNA as a messenger was investigated using cell-free extracts of an extremely thermophilic bacterium, Thermus thermophilus strain HB27, and a hyperthermophilic, acidophilic archaeon, Sulfolobus tokodaii strain 7. Aminoglycoside antibiotics enhanced the reaction; neomycin stimulated it most effectively when the extract of the thermophilic bacterium was used, and paromomycin was the best among the antibiotics tested for the extract of the hyperthermophilic archaeon. A common correlation was found between the stimulation of DNA-directed polypeptide synthesis and the misreading rate in RNA-directed polypeptide synthesis. Spermine stimulated the reaction directed by DNA like in the case of poly(Phe) synthesis directed by poly (rU). The cell-free systems can be used for direct production of proteins from genes in high throughput studies on the structural genomics of thermophilus.
