(1) administration of exotoxin in vivo caused a marked decrease in rna polymerase activity of isolated nuclei at various concentrations of mg(2+), mn(2+) and (nh(4))(2)so(4). a similar action was recorded after addition of exotoxin to isolated nuclei from control or exotoxin-treated mice.

| heterotrophic nature of the cell-free protein-synthesizing system from the strict chemolithotroph, thiobacillus thiooxidans. | a cell-free protein-synthesizing system prepared from the strict chemolithotroph, thiobacillus thiooxidans, was similar to that of heterotrophs. the poly-u directed system had a temperature optimum of 37 c, but in the presence of spermidine (3 mm) the optimum shifted to 45 c. although growth of the chemolithotroph occurs only in acid conditions, the ph optimum for the cell-free system was ph 7.2. the endogenous-directed activity in the presence or absence of spermidine was maximal at ph 7.8. spe ... | 1974 | 4590488 |
