Primary structures of two subunits of NADH: ubiquinone reductase from Neurospora crassa concerned with NADH-oxidation. Relationship to a soluble NAD-reducing hydrogenase of Alcaligenes eutrophus.
The primary structures of the nuclear-encoded 51 kDa and 78 kDa subunits of the respiratory chain NADH: ubiquinone reductase (complex I) from Neurospora crassa mitochondria were determined by sequencing cDNA and the N-terminus of the mature proteins. Both subunits are related to the soluble NAD-reducing hydrogenase of the bacterium Alcaligenes eutrophus. Sequence comparison between these subunits, the corresponding subunits of the bovine complex I and the bacterial NAD-reducing hydrogenase further confirms the binding sites of NAD(H), FMN and three iron-sulfur clusters.
