| linear mitochondrial dnas from yeasts: telomeres with large tandem repetitions. | the terminal structure of the linear mitochondrial dna (mtdna) from the yeast candida parapsilosis was investigated. this mtdna, 30 kb long, has symmetrical ends forming inverted terminal repeats. these repeats are made up of a variable number of tandemly repeating units of 738 bp each; the terminal nucleotide corresponds to a precise position within the last repeat unit sequence. the ends had an open structure accessible to enzymes, with a 5' single-stranded extension of about 110 nucleotides. ... | 1995 | 7715605 |
| extragenomic double-stranded dna circles in yeast with linear mitochondrial genomes: potential involvement in telomere maintenance. | although the typical mitochondrial dna (mtdna) is portrayed as a circular molecule, a large number of organisms contain linear mitochondrial genomes classified by their telomere structure. the class of mitochondrial telomeres identified in three yeast species, candida parapsilosis, pichia philodendra and candida salmanticensis, is characterized by inverted terminal repeats each consisting of several tandemly repeating units and a 5' single-stranded extension. the molecular mechanisms of the orig ... | 2000 | 11071936 |
| t-loops in yeast mitochondria. | mitochondria of several yeast species contain a linear dna genome possessing specific terminal dna structures dubbed mitochondrial telomeres. several tandemly repeated units and a 5' single-stranded extension characterize mitochondrial telomeres in candida parapsilosis, pichia philodendra and candida salmanticensis. resemblance of this type of mitochondrial telomeres to typical nuclear telomeres suggests that they might form t-loop structures. therefore we adopted a protocol for stabilization of ... | 2002 | 16120298 |
| mitochondrial genomes of yeasts of the yarrowia clade. | candida alimentaria, candida deformans, candida galli, and candida phangngensis have been recently reported to be the close relatives of yarrowia lipolytica. to explore this clade of yeasts, we sequenced the mitochondrial genome (mtdna) of these four species and compared it with the mtdna of y. lipolytica. the five mtdnas exhibit a similar architecture and a high level of similarity of protein coding sequences. genome sizes are variable, ranging from 28 017 bp in c. phangngensis to 48 508 bp in ... | 2011 | 22188421 |
| description of groenewaldozyma gen. nov. for placement of candida auringiensis, candida salmanticensis and candida tartarivorans. | dna sequence analyses have demonstrated that species of the polyphyletic anamorphic ascomycete genus candida may be members of described teleomorphic genera, members of the candida tropicalis clade upon which the genus candida is circumscribed, or members of isolated clades that represent undescribed genera. from phylogenetic analysis of gene sequences from nuclear large subunit rrna, mitochondrial small subunit rrna and cytochrome oxidase ii, candida auringiensis (nrrl y-17674(t), cbs 6913(t)), ... | 2016 | 27142089 |
