    Notes: We report the sequence analysis of a 6·8 kb DNA fragment from Saccharomyces cerevisiae chromosome VII. This sequence contains five open reading frames (ORFs) greater than 100 amino acids. There is also an incomplete ORF flanking one of the extremes, G2868, which is the 3′ end of the SCS3 gene (Hosaka et al., 1994). The translated sequence of ORF G2882 shows similarity to the human methylenetetrahydrofolate reductase (Goyette et al., 1994). ORF G2889 shows no significant homologies with the sequences compiled in databases. ORF G2893 corresponds to the gene SUP44, coding for the yeast ribosomal protein S4 (All-Robin et al., 1990). G2873 and G2896 are internal ORFs. The whole sequence of the fragment is available at the EMBL nucleotide sequence database, GenBank and Data Bank of Japan under the Accession Number X94106.

    Notes: We report the sequence analysis of a 10 kb DNA fragment of Saccharomyces cerevisiae chromosome VII. This sequence contains four complete open reading frames (ORFs) of greater than 100 amino acids. There are also two incomplete ORFs flanking the extremes: one of these, G2868, is the 5′ part of the SCS3 gene (Hosaka et al., 1994). ORFs G2853 and G2856 correspond to the genes CEG1, coding for the alfa subunit of the mRNA guanylyl transferase and a 3′ gene of unknown function previously sequenced (Shibagaki et al., 1992). G2864 is identical to SOH1 also reported (Fan and Klein, 1994). The translated sequence of G2861 is similar to the human dnaJ homolog. The nucleotide sequence reported here has been entered in the EMBL Data Library under the Accession Number X87252.

    Effect of anticalmodulin drugs on the action of yeast α factor pheromone (1986)

    Notes: Abstract Saccharomyces cerevisiae α factor pheromone arrest growth of cells of the a mating type (MAT a) at the G1 phase of the cell cycle. When treatment of MAT a cells with α factor was carried out in the presence of anticalmodulin drugs, trifluoperazine or chlorpromazine, the extent of cell growth arrest induced by α factor was reduced or even became undetectable. These results lend support to the hypothesis that calmodulin plays a role as mediator in the action of α factor on MAT a cells.

    A potassium transport mutant of Saccharomyces cerevisiae (1985)

    ISSN: 1432-072X
    Keywords: Saccharomyces cerevisiae ; Potassium transport mutant ; Rubidium transport ; Sodium transport
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A mutant in Saccharomyces cerevisiae required one hundred times more K+ than wild type for the same half maximal growth rate. Mutant cells and wild type cells grown at millimolar K+ did not show significant differences in Rb+ transport. In the mutant, a rapid K+ loss induced by azide or incubation (4 h) in K+-free medium decreased the Rb+ transport K m by one half; in the wild type, those treatments decreased the Rb+ K m twenty and one hundred times, respectively. Mutant and wild type did not show significant differences in Na+ transport and in the Na+ inhibition of Rb+ transport, either in normal-K+ cells or in K+-starved cells. The results suggest that either two systems or one system with two interacting sites mediate K+ transport in S. cerevisiae.

    Differential expression of two genes encoding isoforms of the ATPase involved in sodium efflux in Saccharomyces cerevisiae (1993)

    Notes: Summary The ENA2 gene encoding a P-type ATPase involved in Na+ and Li+ effluxes in Saccharomyces cerevisiae has been isolated. The putative protein encoded by ENA2 differs only in thirteen amino acids from the protein encoded by ENA1/PMR2. However, ENA2 has a very low level of expression and for this reason did not confer significant Li+ tolerance on a Li+ sensitive strain. ENA1 and ENA2 are the first two units of a tandem array of four highly homologous genes with probably homologous functions.

    An indirect optimization method for biochemical systems: Description of method and application to the maximization of the rate of ethanol, glycerol, and carbohydrate production in Saccharomyces cerevisiae (1997)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Three metabolic models for the production of ethanol, glycerol, and carbohydrates in yeast are optimized with respect to different production rates. While originally nonlinear, all three optimization problems are reduced in such a way that methods of linear programming can be used. The optimizations lead to profiles of enzyme activities that are compatible with the physiology of the cells, which guarantees their viability and fitness, and yield higher rates of the desired final end products than the original systems. In order to increase ethanol rate production at least three times, six enzymes must be modulated. By contrast, when the production of glycerol or carbohydrates is optimized, modulation of just one enzyme (in the case of glycerol) or two enzymes (in the case of carbohydrates) is necessary to yield significant increases in product flux rate. Comparisons of our results with those obtained from other methods show great similarities and demonstrate that both are valid methods. The choice of one or the other method depends on the question of interest. © 1997 John Wiley & Sons, Inc. Biotechnol Bioeng 55: 758-772, 1997.

    The deletion of six ORFs of unknown function from Saccharomyces cerevisiae chromosome VII reveals two essential genes: YGR195w and YGR198w (1998)

    Notes: We have deleted six different ORFs of unknown function located on the right arm of Saccharomyces cerevisiae chromosome VII; namely, YGR187c/HGH1, YGR189c, YGR194c, YGR195w, YGR196c and YGR198w. No basic phenotypes could be attributed to the strains deleted in any of genes YGR187c/HGH1, YGR189c, YGR194c and YGR196c. These deletants did not show mating, sporulation or growth defects under any of the conditions tested. However, spores bearing deletions in either the YGR195w or YGR198w genes were unable to develop into macroscopical colonies. The YGR195w gene product shows significant homology with bacterial ribonuclease PH, an enzyme hitherto undescribed in yeasts, and its deletion causes a loss of viability after one to three rounds of cell division. Overexpression of this gene, using a tetracycline-regulatable promoter system, did not cause any effect on the cells. Contrary to what has been reported for prokaryotic homologs, this enzyme could play an essential role in yeast cell biology. The product encoded by the other essential ORF, YGR198w, shows no significant homology with any protein of known function in the databases. Spores bearing the deletion usually germinate and give rise to microcolonies of 50-100 non-viable cells. © 1998 John Wiley & Sons, Ltd.

    Identification and initial characterization of the cytosolic protein Ycr77p (1995)

    Notes: The nucleotide sequence of yeast chromosome III encompassing the previously described open reading frames (ORFs) YCR80w, YCR77c and YCR78c (Oliver et al., 1992) has been updated. In the corrected sequence, these ORFs are replaced by two new ORFs, YCR80w (453 bp) and YCR77c (2391 bp). In addition, the orientation of Ycr79c is reversed to give ORF Ycr79w, which has an unaltered nt sequence. The predicted translation products do not exhibit significant homology to known proteins. ORF Ycr77p encodes an 88 kDa, cytosolic protein. A fraction of the protein is associated with small membranous structures in a salt-sensitive fashion. Initial characterization revealed that the protein is not essential for yeast viability, growth on non-fermentable carbon sources, mating and sporulation. The chromosome III DNA sequence that was used for the analysis has the Accession Number X59720 in the GenBank/EMBL database.

    Notes: The RPL44′ gene from Saccharomyces cerevisiae encoding the ribosomal protein YP1β(L44′) has been found to be linked to the STF1 gene, encoding a stabilizing factor of the F1F0-ATPase inhibitor protein from mitochondria. Evidence of this linkage comes from results obtained from Northern hybridization using a DNA probe that contains a complementary region to the 5′ end of the mRNA of RPL44′. Similarly, a data bank search has shown that RPL44, encoding ribosomal protein YP2α(L44) is linked to the rig gene that encodes ribosomal protein S21.
