Cloning and expression of a Saccharomyces diastaticus glucoamylase gene in Saccharomyces cerevisiae and Schizosaccharomyces pombe.
A recombinant plasmid pool of the Saccharomyces diastaticus genome was constructed in plasmid YEp13 and used to transform a strain of Saccharomyces cerevisiae. Six transformants were obtained which expressed amylolytic activity. The plasmids each contained a 3.9-kilobase (kb) BamHI fragment, and all of these fragments were cloned in the same orientations and had identical restriction maps, whic...
متن کاملA recombination repair gene of Schizosaccharomyces pombe, rhp57, is a functional homolog of the Saccharomyces cerevisiae RAD57 gene and is phylogenetically related to the human XRCC3 gene.
To identify Schizosaccharomyces pombe genes involved in recombination repair, we identified seven mutants that were hypersensitive to both methyl methanesulfonate (MMS) and gamma-rays and that contained mutations that caused synthetic lethality when combined with a rad2 mutation. One of the mutants was used to clone the corresponding gene from a genomic library by complementation of the MMS-sen...
متن کاملA homolog of mammalian antizyme is present in fission yeast Schizosaccharomyces pombe but not detected in budding yeast Saccharomyces cerevisiae
MOTIVATION The antizymes (AZ) are proteins that regulate cellular polyamine pools in metazoa. To search for remote homologs in single-celled eukaryotes, we used computer software based on hidden Markov models. The most divergent homolog detected was that of the fission yeast Schizosaccharomyces pombe. Sequence identities between S.POMBE: AZ and known AZs are as low as 18-22% in the most conserv...
متن کاملGlycoprotein molecules in the walls of Schizosaccharomyces pombe wild-type cells and a morphologically altered mutant resistant to papulacandin B.
Schizosaccharomyces pombe cell walls contain two major glycoprotein species, I and II, with molecular masses of 2 x 10(6) and 5 x 10(5) Da respectively, as determined by gel filtration chromatography and PAGE. The ratio of sugar to protein is higher in species I than in species II. Much of the sugar in both glycoproteins (about 85% in wild-type cells) is O-linked to the peptide moiety. The morp...
متن کاملInvolvement of rhp23, a Schizosaccharomyces pombe homolog of the human HHR23A and Saccharomyces cerevisiae RAD23 nucleotide excision repair genes, in cell cycle control and protein ubiquitination.
A functional homolog (rhp23) of human HHR23A and Saccharomyces cerevisiae RAD23 was cloned from the fission yeast Schizosaccharomyces pombe and characterized. Consistent with the role of Rad23 homologs in nucleotide excision repair, rhp23 mutant cells are moderately sensitive to UV light but demonstrate wild-type resistance to gamma-rays and hydroxyurea. Expression of the rhp23, RAD23 or HHR23A...
