7.2.1.1 FAD complex contains one non-covalently bound FAD, one noncovalently bound riboflavin, ubiquinone-8 and a [2Fe–2S] cluster. The phosphate group is attached at the 5'-position of the ribityl as in authentic FMN and the NADH:quinone oxidoreductase contains approximately 1.7 mol covalently bound FMN per mol non-covalently bound FAD Vibrio cholerae serotype O1
7.2.1.1 riboflavin complex contains one non-covalently bound FAD, one noncovalently bound riboflavin, ubiquinone-8 and a [2Fe–2S] cluster.. The phosphate group is attached at the 5'-position of the ribityl as in authentic FMN and the NADH:quinone oxidoreductase contains approximately 1.7 mol covalently bound FMN per mol non-covalently bound FAD. Each of the single NqrB and NqrC subunits in the NADH:quinone oxidoreductase carries a single FMN Vibrio cholerae serotype O1
7.2.1.1 ubiquinone-8 complex contains one non-covalently bound FAD, one noncovalently bound riboflavin, ubiquinone-8 and a [2Fe–2S] cluster Vibrio cholerae serotype O1
7.2.1.1 [2Fe-2S]-center complex contains one non-covalently bound FAD, one noncovalently bound riboflavin, ubiquinone-8 and a [2Fe–2S] cluster Vibrio cholerae serotype O1
