The filamentous fungus Aspergillus niger is widely exploited by the fermentation industry for the production of enzymes and organic acids, particularly citric acid. We sequenced the 33.9-megabase genome of A. niger CBS 513.88, the ancestor of currently used enzyme production strains. A high level of synteny was observed with other aspergilli sequenced.… (More)
Isolated yeast mitochondria incorporate added UTP into RNA. Amongst the products formed are the two rRNAs, 4S RNA and several components presumed to be mRNAs. In omega+ strains (containing an intervening sequence in the 21S rRNA gene) besides mature 21S rRNA a transcript could be detected still containing nucleotide sequences transcribed from this… (More)
The nucleotide sequence of a Spirodela chloroplast DNA fragment, which directs the synthesis of a approximately 15 kD chloroplast ribosomal protein in an E. coli cell free system, has been determined. The deduced aminoacid sequence of the open reading frame shows extensive homology with E. coli ribosomal protein L16. Primer extension analysis, S1 nuclease… (More)
We have developed a two-dimensional method for simultaneously mapping on the yeast mtDNA genome all the transcripts representing more than 0.01% of mtRNA. In two yeast strains, Saccharomyces carlsbergensis NCYC-74 and Saccharomyces cerevisiae KL14-4A, about 25 discrete transcripts were found apart from tRNAs. The mtDNAs of these strains differ by the… (More)
We show that the mitochondrial protein known as Var 1 is identical with the ribosome-associated protein previously identified as a product of mitochondrial protein synthesis. Although indirect evidence suggests that Var 1 is not involved in ribosome biosynthesis, a definite conclusion has to await further investigation.
Mitochondrial DNAs from yeast, Neurospora, rat and calf do not contain internally methylated cytosine in -CCGG- sequences.
We have constructed a physical map of Kluyveromyces lactis mtDNA using the restriction enzymes HindII and HindIII. In contrast to Saccharomyces, the genes for the large and small ribosomal RNAs are much closer to each other, being separated by a maximal distance of 2,250 base pairs.
We have characterized the ribosomal proteins from Spinacia chloroplasts using two-dimensional gel electrophoresis. The 30S and 50S subunits contain 23–25 and 36 ribosomal proteins, respectively. In contrast to prokaryotic ribosomes, chloroplast ribosomes contain at least one (and possibly two) phosphorylated ribosomal proteins. Isolated chloroplasts… (More)
