General annotation (Comments)
| Function | Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone By similarity. This is the largest subunit of complex I and it is a component of the iron-sulfur (IP) fragment of the enzyme. It may form part of the active site crevice where NADH is oxidized. |
| Catalytic activity | NADH + ubiquinone = NAD+ + ubiquinol. NADH + acceptor = NAD+ + reduced acceptor. |
| Cofactor | Binds 1 2Fe-2S cluster per subunit By similarity. Binds 2 4Fe-4S clusters per subunit By similarity. |
| Subunit structure | Complex I is composed of 45 different subunits. Ref.7 |
| Subcellular location | |
| Involvement in disease | Mitochondrial complex I deficiency (MT-C1D) [MIM:252010]: A disorder of the mitochondrial respiratory chain that causes a wide range of clinical manifestations from lethal neonatal disease to adult-onset neurodegenerative disorders. Phenotypes include macrocephaly with progressive leukodystrophy, non-specific encephalopathy, cardiomyopathy, myopathy, liver disease, Leigh syndrome, Leber hereditary optic neuropathy, and some forms of Parkinson disease. |
| Sequence similarities | Belongs to the complex I 75 kDa subunit family. Contains 1 2Fe-2S ferredoxin-type domain. |
