Abstract


Expression of the glucoamylase-encoding gene (STA2) in Saccharomyces cerevisiae was previously shown to be regulated transcriptionally by both positive and negative factors. The objective of this work was to identify the cis-acting elements responsible for STA2 transcriptional activation as well as the transcriptional repressor effects of STA10 and MATa/MAT alpha. We identified two upstream activation regions (UAS). Three repressor regions responsive to STA10-mediated repression were identified, as well as two regions for down-regulation of STA2 expression. MATa/MAT alpha repression appears to effect STA2 expression either downstream from the translational start site or, indirectly, since no functional a1/alpha 2-responsive sequence was identified in the promoter region.
