Regulation of RNA synthesis in higher plant cells by the action of a nucleoside triphosphatase

The influence of nucleoside triphosphates in relation to divalent cations on RNA synthesis of cells from a suspension culture from parsley was investigated. The data obtained from experiments with isolated nuclei and with an in vitro system with highly purified RNA polymerase I were compared with a...

Description
Summary:The influence of nucleoside triphosphates in relation to divalent cations on RNA synthesis of cells from a suspension culture from parsley was investigated. The data obtained from experiments with isolated nuclei and with an in vitro system with highly purified RNA polymerase I were compared with a chromatin-bound nucleoside triphosphatase activity within the nucleus. The results might suggest a regulatory role of the nucleoside triphosphatase activity in RNA synthesis.
