title: Mitochondrial genome of Saccharomyces douglasii: genes coding for components of the protein synthetic apparatus.
abstract: Mitochondrial genes coding for some components of the protein synthetic apparatus in S. douglasii have been studies in detail. A region containing stretches of high homology to the S. cerevisiae tRNA synthesis locus (TSL) and the tRNA(fmet) gene has been identified and sequenced. The organization of this region was very similar to that present in S. cerevisiae, including the presence of a possible transcription starting signal. The S. douglasii TSL gene is shorter due to several deletions which, however, do not involve the regions coding for RNA domains know to be required for the catalytic activity of mitochondrial RNAse P. The S. douglasii LSU rRNA gene has been shown to contain a typical group I intron highly homologous to its S. cerevisiae counterpart, except for the absence of the open reading frame which in S. cerevisiae codes for I-SceI endonuclease.
