Similar short elements in the 5′ regions of the STA2 and SGA genes from Saccharomyces cerevisiae

Abstract
The 5′ regions of the SGA and ST A2 genes, encoding the intra‐ and extracellular glucoamylases, respectively, from Saccharomyces cerevisiae have been sequenced. In addition, the transcription initiation sites have been determined. Four distinct short elements (named I to IV) were found in both genes. Element III has the consensus sequence PuCATTTAPiG with a bilateral symmetry around the central T, and is present in both genes as a direct repeat. This motive seems responsible for the coregulation of ST A2 and SGA by the repressor ST A10 gene of S. cerevisiae.
