Figure 1

A β-galactosidase expression system in yeast. The E. coli β-galactosidase gene is under the control of gall-gal 10 UASg and the cycl promoter. In glucose medium, this gene is not expressed and remains repressed, while activated in galactose medium by the expression of chromosomal proteins Gal4 and Gal80. The Gal4-Gal80 complex disrupts nucleosomes and binds DNA at UASg to activate transcription.
