    Notes: Summary The 5′-flanking region of the Saccharomyces cerevisiae catalase T gene (CTT1) and the part of the gene coding for the N-terminus of catalase T were sequenced. 5′-Ends of transcripts of the region were located by S1 nuclease mapping and primer extension. To analyse control elements in the upstream region, a CTT1-lacZ gene fusion was constructed. Deletion analysis was carried out within a part of the 5′-flanking region showing homology to the upstream region of the yeast CYC1 gene. Like the CTT1 gene, this gene is controlled by heme, oxygen and glucose. The results obtained show that the CTT1 gene is positively controlled by heme. Tentative evidence has been obtained for the involvement of upstream sequences homologous to USA1 and USA2 of the CYC1 gene in heme control. Further, a negative site has been located between the upstream activator sites and the transcription start. Within this negative region a ten base-pair sequence was detected that shows high homology to a sequence located within a negative control region of the CYC1 gene and some homology to the negative control elements of the S. cerevisiae CAR1 and CAR2 genes.

    Stress signaling in yeast (1995)
    New York, NY : Wiley-Blackwell

    Notes: In the yeast Saccharomyces cerevisiae three positive transcriptional control elements are activated by stress conditions: heat shock elements (HSEs), stress response elements (STREs) and AP-1 responsive elements (AREs). HSEs bind heat shock transcription factor (HSF), which is activated by stress conditions causing accumulation of abnormal proteins. STREs mediate transcriptional activation by multiple stress conditions. They are controlled by high osmolarity via the HOG signal pathway, which comprises a MAP kinase module and a two-component system homologous to prokaryotic signal transducers. AREs bind the transcription factor Yap1p. The three types of control elements seem to have overlapping, but distinct functions. Some stress proteins encoded by HSE-regulated genes are necessary for growth of yeast under moderate stress, products of STRE-activated genes appear to be important for survival under severe stress and ARE-controlled genes may mainly function during oxidative stress and in the response to toxic conditions, such as caused by heavy metal ions.

    Control of peroxisome proliferation in Saccharomyces cerevisiae by ADR1, SNF1 (CAT1, CCR1) and SNF4 (CAT3)Dedicated to Profesor Wilhelm Fleischhacker on the occasion of his 60th birthday. (1992)

    Notes: The Saccharomyces cerevisiae ADR1 gene has recently been demonstrated to control transcription of several genes encoding peroxisomal proteins or proteins necessary for peroxisome formation. Therefore, the effect of two other genes (SNF1 (CAT1, CCR1) and SNF4 (CAT3)) known to control derepression of glucose-repressible genes was studied. Levels of transcripts of genes encoding catalase A, fatty acid β-oxidation enzymes and of the PAS1 gene are reduced in snf1 and snf4 mutants of ethanol as well as on oleic acid medium. By immunogold labelling with an antibody directed against peroxisomal thiolase, clusters of peroxisomes were detected in wild-types cells, whereas smaller single peroxisomes were observed in adr1 mutant cells. Results of immunofluorescence experiments are consistent with these observations. No peroxisomes were detected in snf1 and snf4 mutants by immunogold labelling as well as by imunofluorescence.
