The atp6 gene, encoding the ATP6 subunit of F(1)F(0)-ATP synthase, has thus far been found only as an mtDNA-encoded gene. However, atp6 is absent from mtDNAs of some species, including that of Chlamydomonas reinhardtii. Analysis of C. reinhardtii expressed sequence tags revealed three overlapping sequences that encoded a protein with similarity to ATP6 proteins. PCR and 5'- and 3'-RACE were use...
RNA editing and cytoplasmic male sterility are two important phenomena in higher plant mitochondria. To determine whether correlations might exist between the two, RNA editing in different tissues of Sorghum bicolor was compared employing reverse transcription-PCR and subsequent sequence analysis. In etiolated shoots, RNA editing of transcripts of plant mitochondrial atp6, atp9, nad3, nad4, and...
Complete nucleotide sequences have been determined for atp6 from Suillus luteus and cox3 from Suillus sinuspaulianus (Boletales, Hymenomycetes, Basidiomycota), which code for ATPase subunit 6 and cytochrome oxidase subunit 3, respectively. These sequences were used to design PCR primers for the amplification of partial atp6 and cox3 sequences from other members of the Boletales and outgroup tax...
In eukaryotes, horizontal gene transfer is a rare event. Here we show that the mitochondrial genome of a lower fungus, Allomyces macrogynus, has an extra DNA segment not present in a close relative, Allomyces arbusculus. This insert consists of the C terminus of a foreign gene encoding a subunit of the ATP synthetase complex (atp6) plus an open reading frame encoding an endonuclease. The insert...
Mitochondrial DNA mutations at MT-ATP6 gene are relatively common in individuals suffering from striatal necrosis syndromes. These patients usually do not show apparent histochemical and/or biochemical signs of oxidative phosphorylation dysfunction. Because of this, MT-ATP6 is not typically analyzed in many other mitochondrial disorders that have not been previously associated to mutations in t...
Three nuclear genes, lsu-rDNA (encoding nuclear large subunit rDNA), ITS (encoding the rDNA internal transcribed spacers and 5.8 S rDNA) and rpb2 (encoding the second largest subunit of RNA polymerase II), and the mitochondrial gene atp6 (encoding the sixth subunit of ATP synthase), were sequenced from all recognized Sparassis lineages. Sparassis latifolia sp. nov. from boreal coniferous forest...
OBJECTIVE Charcot-Marie-Tooth (CMT) disease is the most common inherited neuromuscular disorder, affecting 1 in 2,500 individuals. Mitochondrial DNA (mtDNA) mutations are not generally considered within the differential diagnosis of patients with uncomplicated inherited neuropathy, despite the essential requirement of ATP for axonal function. We identified the mtDNA mutation m.9185T>C in MT-ATP...
As previously established in yeast, two sequences within mRNAs are responsible for their specific localization to the mitochondrial surface-the region coding for the mitochondrial targeting sequence and the 3'UTR. This phenomenon is conserved in human cells. Therefore, we decided to use mRNA localization as a tool to address to mitochondria, a protein that is not normally imported. For this pur...
ATP synthase 8 (ATP8) and ATPase synthase 6 (ATP6) play an important role in mitochondrial ATPase assembly. Mutations in either of these units could affect the ATP processing and the respiration chain in mitochondria. To find out if there were differences in gene diversity between Tibetan yaks and domestic cattle, we sequenced the ATP8 and ATP6 genes in 66 Tibetan yaks and 81 domestic cattle. W...
We explore the possibility of re-engineering mitochondrial genes and expressing them from the nucleus as an approach to rescue defects arising from mitochondrial DNA mutations. We have used a patient cybrid cell line with a single point mutation in the overlap region of the ATP8 and ATP6 genes of the human mitochondrial genome. These cells are null for the ATP8 protein, have significantly lower...
