Description:
Fumarate and nitrate reduction (FNR) regulatory proteins are O2-sensing bacterial transcription factors that control the switch between aerobic and anaerobic metabolism. Under anaerobic conditions [4Fe-4S]2+-FNR exists as a DNA-binding homodimer. In response to elevated oxygen levels, the [4Fe-4S]2+ cluster undergoes a rapid conversion to a [2Fe-2S]2+ cluster, resulting in a...
