Characterization
In Escherichia coli, the switch between aerobic and anaerobic metabolism is partly regulated the transcriptional regulator FNR. This protein has a dual function: it activates genes involved in anaerobic metabolism and represses genes involved in aerobic metabolism. FNR expression is constitutive, but its activity is directly affected by the presence of oxygen which oxidizes of an essential [4Fe-4S] cluster. The expression of the ndh gene is repressed by FNR in anaerobic conditions.
