| Abstract: | Summary Mn++-stimulated poly(A) synthetase activity of dialyzed ammonium sulfate fraction (0–50% saturation) of nuclear extracts from rat liver is dependent on salt addition to the incubation mixture. The corresponding soluble cytoplasmic activity is inhibited by the salt concentration required for nuclear activity. |
