Abstract

Escherichia coli is adroit in exploiting environmental energy sources to its greatest profit. A key strategy is to channel electron transport from donor to a terminal acceptor(s) so that the voltage drop is maximal. At the level of transcription, the goal is achieved by the interaction of three global regulatory systems, Fnr, NarL/NarX and ArcB/ArcA. In addition, the regulator FhlA is involved in a cascade-controlled pathway for the formate branch of the pyruvate fermentation pathway.
