Comments
  • FUNCTION: NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. 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).
  • CATALYTIC ACTIVITY: NADH + quinone = NAD+ + quinol.
  • SUBUNIT: Composed of 13 different subunits. Subunits nuoA, H, J, K, L, M, N constitute the membrane sector of the complex (By similarity).
  • SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
  • SIMILARITY: Belongs to the complex I subunit 3 family.
