FIGURE 3.

Rap1, Gcr1, and Abf1 transcription factor binding sites which are conserved in the glycolytic and fermentation promoters of S. cerevisiae, S. kudriavzevii, and S. eubayanus. The boxes indicate the location in the promoter of the binding sites for the Rap1 (red), Gcr1 (blue), and Abf1 (yellow) transcription factors which are experimentally shown to be functional in S. cerevisiae. The boxes contain the alignments of the three promoters at the transcription factor binding sites, conserved nucleotides are indicated in green. The Gcr1 and Rap1 sites in the ADH1 promoter were not identified in SeADH1p.
