NQO contains 14 central subunits and up to 32 accessory subunits. NQO contains FMN and 8 to 9 iron-sulfur clusters. Seven of the iron-sulfur clusters form a linear electron transfer chain between the FMN and quinone. For more details see NADH:ubiquinone oxidoreductase. Disease Relevance Structural highlights
