title: Transcriptional control of yeast phosphoglycerate mutase-encoding gene.
abstract: Yeast genes encoding enzymes of the glycolytic pathway are highly expressed due to transcriptional control elements in their promoters. We provide data on such elements in the 5'-noncoding sequences of the Saccharomyces cerevisiae GPM1 gene, encoding phosphoglycerate mutase. Using fusions to the lacZ reporter gene, a detailed deletion analysis was performed. A palindromic sequence was shown to function as an upstream activation site (UAS) and two upstream repressing sites (URS1 and URS2) were located. Western and Northern blot analyses were used to substantiate the data obtained in enzymatic measurements. The regulatory sequences were shown to be functional in the heterologous CYC1 promoter. In addition, a promoter region was detected which mediated general glycolytic control by the GCR1 regulatory factor.
