NADH + H + + acceptor ⇌ NAD + + reduced acceptor. NADH dehydrogenase is a flavoprotein that contains iron-sulfur centers. NADH dehydrogenase is used in the electron transport chain for generation of ATP. The EC term NADH dehydrogenase (quinone) (EC 1.6.5.11) is defined for NADH dehydrogenases that use a quinone (excluding ubiquinone) as the ...
Also known as Complex I, this enzyme is the largest of the respiratory complexes. The structure is L-shaped with a long, hydrophobic transmembrane domain and a hydrophilic domain for the peripheral arm that includes all the known redox centres and the NADH binding site. The MT-ND2 product and the rest of the mitochondrially encoded subunits are ...
NAD + to NADH. FMN to FMNH 2. CoQ to CoQH 2.. Complex I is the first enzyme of the mitochondrial electron transport chain.There are three energy-transducing enzymes in the electron transport chain - NADH:ubiquinone oxidoreductase (complex I), Coenzyme Q – cytochrome c reductase (complex III), and cytochrome c oxidase (complex IV).

MT-ND3 is located in human mitochondrial DNA from base pair 10,059 to 10,404. [5] The MT-ND3 gene produces a 13 kDa protein composed of 115 amino acids. [9] [10] MT-ND3 is one of seven mitochondrial genes encoding subunits of the enzyme NADH dehydrogenase (ubiquinone), together with MT-ND1, MT-ND2, MT-ND4, MT-ND4L, MT-ND5, and MT-ND6.
The structure is L-shaped with a long, hydrophobic transmembrane domain and a hydrophilic domain for the peripheral arm that includes all the known redox centres and the NADH binding site. MT-ND5 and the rest of the mitochondrially encoded subunits are the most hydrophobic of the subunits of Complex I and form the core of the transmembrane region.
NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 12 is an enzyme that in humans is encoded by the NDUFA12 gene. [ 5 ] [ 6 ] [ 7 ] The NDUFA12 protein is a subunit of NADH dehydrogenase (ubiquinone) , which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain .
NADH-coenzyme Q oxidoreductase, also known as NADH dehydrogenase or complex I, is the first protein in the electron transport chain. [18] Complex I is a giant enzyme with the mammalian complex I having 46 subunits and a molecular mass of about 1,000 kilodaltons (kDa). [19]
NADH dehydrogenase [ubiquinone] iron-sulfur protein 4, mitochondrial (NDUFS4) also known as NADH-ubiquinone oxidoreductase 18 kDa subunit is an enzyme that in humans is encoded by the NDUFS4 gene. [ 5 ] [ 6 ] This gene encodes a nuclear-encoded accessory subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase ( complex I , or ...
