General annotation (Comments)
| Function | 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 By similarity. HAMAP MF_01351 |
| Catalytic activity | NADH + quinone = NAD+ + quinol. HAMAP MF_01351 |
| Cofactor | Binds 2 4Fe-4S clusters per subunit By similarity. HAMAP MF_01351 |
| Subunit structure | NDH-1 is composed of 14 different subunits. Subunits NuoA, H, J, K, L, M, N constitute the membrane sector of the complex By similarity. |
| Subcellular location | Cell inner membrane; Peripheral membrane protein Potential HAMAP MF_01351. |
| Sequence similarities | Belongs to the complex I 23 kDa subunit family. Contains 2 4Fe-4S ferredoxin-type domains. |
