Abstract excerpt
The alternative nitrogenase of Rhodobacter capsulatus is expressed only under conditions of nitrogen and molybdenum depletion. The analysis of anfA-lacZ fusions demonstrated that this dual control occurred at the level of transcription of anfA, which encodes a transcriptional activator specific f...
