The ATP synthase subunit 9 gene of Aspergillus nidulans: sequence and transcription. 1986

M Ward, and G Turner

We have determined the nucleotide sequence of the Aspergillus nidulans nuclear gene oliC31, which encodes subunit 9 of mitochondrial ATP synthase. The open reading frame contains no introns and specifies a predicted protein of 143 amino acids comprising a pre-sequence of 62 residues and a mature protein of 81 residues. The amino acid homology with the equivalent Neurospora crassa protein is 50% for the pre-sequence and 80% for the mature protein. A comparison with this and other imported mitochondrial proteins has revealed conserved regions which may be important for transport or subsequent processing. Multiple transcription initiation and polyadenylation sites have been identified. The promoter region of the oliC31 gene is characterised by long pyrimidine-rich tracts preceding the transcription initiation sites.

UI	MeSH Term	Description	Entries
D008928	Mitochondria	Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes.

D003062	Codon	A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (CODON, TERMINATOR). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, TRANSFER) complementary to all codons. These codons are referred to as unassigned codons (CODONS, NONSENSE).
