The global regulator FNR (for fumarate nitrate reduction) controls the transcription of >100 genes whose products facilitate adaptation of Escherichia coli to growth under O2-limiting conditions. Previous Mössbauer studies have shown that anaerobically purified FNR contains a [4Fe-4S]2+ cluster that, on exposure to oxygen, is converted into a [2Fe-2S]2+ cluster, a process that decreases DNA bin...
We report the generation and characterization of an intermediate in a mutant form of the toluene/o-xylene monooxygenase hydroxylase component from Pseudomonas stutzeri OX1. The reaction of chemically reduced I100W variant in the presence of the coupling protein, ToMOD, with dioxygen was monitored by stopped-flow UV/visible spectroscopy. Rapid-freeze quench (RFQ) samples were also generated for ...
