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 By similarity. |
| 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 By similarity. |
| Subcellular location | Mitochondrion inner membrane By similarity. Note: Matrix and cytoplasmic side of the mitochondrial inner membrane By similarity. |
| Post-translational modification | Acetylation of Lys-84 is observed in liver mitochondria from fasted mice but not from fed mice. |
| Sequence similarities | Belongs to the complex I 75 kDa subunit family. Contains 1 2Fe-2S ferredoxin-type domain. |
