EPR signals assigned to Fe/S cluster N1c of the Escherichia coli NADH:ubiquinone oxidoreductase (complex I) derive from cluster N1a



EPR signals assigned to Fe/S cluster N1c of the Escherichia coli NADH:ubiquinone oxidoreductase (complex I) derive from cluster N1a



Biochemistry 44(5): 1653-1658



The proton-pumping NADH:ubiquinone oxidoreductase, which is also called respiratory complex 1, transfers electrons from NADH to ubiquinone via one flavin mononucleotide (FMN) and up to nine iron-sulfur clusters. A structural minimal form of complex I consisting of 14 different subunits called NuoA to NuoN (or Nqo1 to Nqo14) is found in bacteria. The isolated Escherichia coli complex I can be split into a NADH dehydrogenase fragment, a connecting fragment, and a membrane fragment.
