Abstract
The photosynthetic bacterium Rhodobacter capsulatus has been shown to carry out nitrogenase "switch-off," a rapid, reversible inhibition of in vivo activity. Here, we demonstrate that highly nitrogen-limited cultures of both the wild-type strain and a draT draG mutant are capable of nitrogenase switch-off while moderately nitrogen-limited cultures show instead a "magnitude" response, with a decrease in in vivo nitrogenase activity that is proportional to the amount of added NH4+.
摘要
光合细菌荚膜红细菌已被证明能进行固氮酶“关闭”，即对体内活性进行快速、可逆的抑制。在此，我们证明野生型菌株和draT draG突变体的高度氮限制培养物都能够进行固氮酶关闭，而中度氮限制培养物则表现出“量值”反应，体内固氮酶活性的降低与添加的NH4+量成比例。
