Abstract
The time course of appearance of respiratory nitrate reductase in Escherichia coli after induction by nitrate was analyzed under different conditions, and the inhibitory effects of oxygen, chloramphenicol, and rifampin were compared. Oxygen appeared to inhibit the synthesis of nitrate reductase at the level of transcription. In addition, the translation or some later steps of enzyme formation were blocked.
摘要
在不同条件下分析了硝酸盐诱导后大肠杆菌中呼吸硝酸盐还原酶出现的时间进程，并比较了氧气、氯霉素和利福平的抑制作用。氧气似乎在转录水平上抑制硝酸盐还原酶的合成。此外，酶形成的翻译或一些后续步骤被阻断。
