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 2Fe-2S cluster Potential. |
| Subunit structure | Complex I is composed of at least 49 different subunits. This is a component of the flavoprotein-sulfur (FP) fragment of the enzyme. |
| Subcellular location | Mitochondrion inner membrane By similarity. Note: Matrix and cytoplasmic side of the mitochondrial inner membrane By similarity. |
| Sequence similarities | Belongs to the complex I 24 kDa subunit family. |
| Sequence caution | The sequence AAC78260.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAB80751.1 differs from that shown. Reason: Erroneous gene model prediction. |
