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_01394
Catalytic activity	NADH + quinone = NAD+ + quinol. HAMAP MF_01394
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. HAMAP MF_01394
Subcellular location	Cell inner membrane; Multi-pass membrane protein By similarity HAMAP MF_01394.
Sequence similarities	Belongs to the complex I subunit 3 family.
