| Protein existence | Evidence at transcript level |
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. |
| Catalytic activity | NADH + ubiquinone = NAD+ + ubiquinol. NADH + acceptor = NAD+ + reduced acceptor. |
| Cofactor | Binds 1 FMN Potential. Binds 1 4Fe-4S cluster Potential. |
| Subunit structure | Complex I is composed of about 45 different subunits. This is a component of the flavoprotein-sulfur (FP) fragment of the enzyme By similarity. |
| Subcellular location | Mitochondrion inner membrane; Peripheral membrane protein; Matrix side By similarity. |
| Sequence similarities | Belongs to the complex I 51 kDa subunit family. |
