The acyl-carrier protein in Neurospora crassa mitochondria is a subunit of NADH:ubiquinone reductase (complex I).

We determined the primary structure of a 9.6-kDa subunit of the respiratory chain NADH:ubiquinone reductase (complex I) from Neurospora crassa mitochondria and found a close relationship between this subunit and the bacterial or chloroplast acyl-carrier protein. The degree of sequence identity amounts to 80% in a region of 19 residues around the serine to which the phosphopantetheine is bound.

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.

Primary structure of the nuclear-encoded 18.3 kDa subunit of NADH: ubiquinone reductase (complex I) from Neurospora crassa mitochondria.

The primary structure of the nuclear-encoded 18.3 kDa subunit of the respiratory chain NADH: ubiquinone reductase (complex I) from Neurospora crassa was determined by sequencing cDNA and the N-terminus of the protein. The cDNA contains an open reading frame for a protein of 206 amino acids.

The iron-sulfur clusters in the two related forms of mitochondrial NADH: ubiquinone oxidoreductase made by Neurospora crassa.

Two related forms of the respiratory-chain complex, NADH: ubiquinone oxidoreductase (Complex I) are synthesized in the mitochondria of Neurospora crassa. Normally growing cells make a large, piericidin-A-sensitive form, which consists of some 23 different nuclear- and 6-7 mitochondrially encoded subunits. Cells grown in the presence of chloramphenicol make a small, piericidin-A-insensitive form which consists of only approximately 13 nuclear-encoded subunits.

cDNA and genomic DNA sequence of the 21.3 kDa subunit of NADH:ubiquinone reductase (complex I) from Neurospora crassa.

The primary structure of a nuclear-encoded subunit of the respiratory chain NADH:ubiquinone reductase (complex I) from Neurospora crassa was determined by sequencing cDNA, genomic DNA and the N-terminus of the protein. The sequence correlates to a protein of 200 amino acids and a molecular mass of 21349 Da. The protein is synthesized without a cleavable presequence.
