    A novel mutation that affects utilization of galactose in Saccharomyces cerevisiae (1980)
    Springer
    Current genetics 2 (1980), S. 115-120 
    Details
    ISSN: 1432-0983
    Keywords: Galactose fermentation ; Saccharomyces cerevisiae ; Regulatory mutant
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary A novel type of regulatory mutation for galactose metabolism in Saccharomyces cerevisiae is described. The mutation named gal11 was recessive, non-allelic to GAL4, GAL80, GAL2, or GAL3, and unlinked to the gene cluster of GAL1, GAL10, and GAL7. It caused a ‘coordinate’ reduction of galactokinase, galactose-1-P uridylyl transferase, and UDP-glucose 4-epimerase by a factor of more than 5, rendering the mutant cells galactose-nonfermenting. The effect of the mutation was manifested not only in cells grown on galactose but also in cells constitutively synthesizing the galactose-metabolizing enzymes.

    Transcriptional units of GAL genes in Saccharomyces cerevisiae determined by ultraviolet light mapping (1980)
    Springer
    Current genetics 2 (1980), S. 223-228 
    Details
    ISSN: 1432-0983
    Keywords: Transcriptional Units ; GAL Genes ; Saccharomyces cerevisiae ; UV mapping
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The size of the transcriptional unit of the structural genes for three galactose-metabolizing enzymes which form a cluster on chromosome II in Saccharomyces cerevisiae was studied by the ultraviolet light (UV)-mapping technique. Thus the size of the primary transcripts of GAL7 for galactose-1-phosphate uridylyl transferase, GAL10 for uridine diphosphoglucose 4-epimerase, or GAL1 for galactokinase were estimated to be 0.81 x 106, 1.1 x 106, or 1.3 x 106 respectively. In the light of these data together with the known directions of transcription of the genes, we concluded that each of three genes was transcribed from its own promoter.

    Purification of yeast histones competent for nucleosome assembly in vitro (1994)
    New York, NY [u.a.] : Wiley-Blackwell
    Yeast 10 (1994), S. 319-331 
    Details
    ISSN: 0749-503X
    Keywords: Saccharomyces cerevisiae ; histones ; nucleosome assembly ; Life and Medical Sciences ; Genetics
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Biology
    Notes: We have developed a procedure to purify nucleosomal assembly-competent histones as a mixture of H2A, H2B, H3 and H4 from isolated nuclei of the yeast Saccharomyces cerevisiae with a purity of 70-80%. The mixture contained each of the histone subunits approximately at the equi-molar ratio. Plasmid pBR322 DNA was assembled into nucleosomes with the purified yeast histones in the presence of nucleoplasmin from unfertilized eggs of the frog Xenopus laevis. The efficiency of assembly of yeast histones was comparable to that of core histones purified from HeLa cells. The length of DNA fragment wrapping around a core histone particle and the molar ratio of histone components in an assembled nucleosome particle were estimated to be 150 ± 10 bp long and H2A:H2B:H3:H4 = 1·0:0·9:0·9:1·0, respectively.
