Enzyme Information
| 1.6.99.3 |
NADH dehydrogenase.
based on mapping to UniProt P49821
NADH + acceptor = NAD(+) + reduced acceptor.
-!- After preparations have been subjected to certain treatments cytochrome c may act as acceptor. -!- Under normal conditions, two protons are extruded from the cytoplasm or the intramitochondrial or stromal compartment. -!- Present in a mitochondrial complex as EC 7.1.1.2. -!- Formerly EC 1.6.2.1.
|
| 7.1.1.2 |
NADH:ubiquinone reductase (H(+)-translocating).
based on mapping to UniProt P49821
NADH + ubiquinone + 5 H(+)(In) = NAD(+) + ubiquinol + 4 H(+)(Out).
-!- The complex is present in mitochondria and aerobic bacteria. -!- Breakdown of the complex can release EC 1.6.99.3. -!- In photosynthetic bacteria, reversed electron transport through this enzyme can reduce NAD(+) to NADH. -!- Formerly EC 1.6.5.3.
