Gene Disruptions-The LEU2 gene of S. cerevisiae was integrated at various sites in the CANl locus by one-step gene disruption method (Rothstein, ). After subcloning of the kb long BamHI-Chin fragment of the CANl gene (see Fig. 1) in pUC18 (pWH), this plasmid was digested with DNase in the presence of manganese.

In each case the fusion protein has OMP decarboxylase activity as assayed by.   In addition, we evaluated the effect of S. cerevisiae MIG1 protein on this promoter. 2. Materials and methods Strains, transformation and culture conditions. S. cerevisiae strains WA (MATa SUC2 ade can his,15 leu, trp ura) and IMb (MATa his4 leu, sta° STA10) were from our collection.

  An integrated GAL1-lacZ fusion provided a useful phenotypic marker for the gal80 − regulatory mutation in Saccharomyces minimal glucose plates containing a β-galactosidase indicator, a GAL80 strain containing the fusion gave white colonies, whereas a gal80 − strain gave blue colonies. This color difference was used to isolate the GAL80 gene from a plasmid . Disruption of the ORF YGLc was also made in (MATa /α ura3‐52/URA3 his3Δ1/HIS3 leu2‐3,/LEU2 trp1‐/TRP1). For routine cultures, S. cerevisiae was grown on glucose complete medium (YPD): 1% yeast extract, 2% peptone and 2% glucose. Glycerol complete medium (YPG) contained 3% (v/v) of glycerol instead of glucose. A new reporter system has been developed for quantifying gene expression in the yeast Saccharomyces cerevisiae. The system relies on two different reporter genes, Renilla and firefly luciferase, to evaluate regulated gene expression. The gene encoding Renilla luciferase is fused to a constitutive promoter (PGK1 or SPT15) and integrated into the yeast genome at the CAN1 locus as a control. In the present study, data from functional analysis of a septin component Cdc11 containing four different epitopes shed light on the usefulness of the tagging vectors for rapid analysis of gene function in S. cerevisiae. 2 Materials and methods Strains and culture condition. Table 1 lists the yeast strains and plasmids used in this study.
