| SO_4506 | ifcA | SO_4506 | SO_1421 | Iron-sulfur cluster-binding protein. | Periplasmic tetraheme flavocytochrome IfcA; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily. | 0.890 |
| SO_4506 | nuoCD | SO_4506 | SO_1019 | Iron-sulfur cluster-binding protein. | NADH-ubiquinone oxidoreductase subunit CD NuoCD; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family. | 0.999 |
