Thermobacterium acidophilus

Extracts of certain bacteria requiring 2-deoxyribonucleosides, namely, Lactobacillus helveticus, Lactobacillus delbriickii, and Thermobacterium acidophilus R 26, catalyze the transfer of the 2-deoxy-D-ribosyl group from one purine or pyrimidine to another. " 2-Deoxyribosyl -uracil, thy-... 

Enzyme preparations from Lactobacillus delbrueckii and Thermobacterium acidophilus R 26 catalyze similar transfer reactions, as do extracts of E. coli. ... 

A large number of experimental facts and a series of indirect experiments have led Brachet and Caspersson, independently of each other, to the conclusion that nucleic acids are involved in protein synthesis. The concentration of RNA in the cell is approximately proportional to the growth of Bac. lactic aerogenes, thus leading Caldwell to consider RNA as being the template itself. Jeener has shown for his part that during experimental modifications of the volumes of the nucleus and the cytoplasm of Thermobacterium acidophilus protein synthesis was quantitatively related to the level of RNA. Finally, direct experiments have shown that in various cells or fragments of cells, treatment with ribonuclease suppresses protein synthesis.
