• 論文の詳細を見る

• Cellular DNA and RNA syntheses in the strains carrying a mutation in relA gene in combination with a mutation in either dnaK or dnaJ gene were examined. RNA synthesis was relaxed in either combination both in the presence and in the absence of an exess amount of L-valine. However, DNA syntheses remained inhibited under the same conditions, suggesting that the thermosensitive DNA synthesis and RNA synthesis which are coexhibited in the dnaK(Ts) and dnaJ(Ts) mutants are not directly related each other. Thus the relaxed RNA synthesis in the double mutants did not reflect on the restoration of their thermoresistant DNA synthesis.
