pGAL1/10 - bidirectional inducible promoters from Saccharomyces cerevisiae
The GAL1 and GAL10 promoters are two tightly linked, yet functionally distinct, promoters found in the yeast Saccharomyces cerevisiae. They regulate the expression of genes involved in galactose metabolism. The GAL1 promoter drives the expression of the GAL1 gene, which encodes galactokinase, an enzyme responsible for the phosphorylation of galactose. The GAL10 promoter controls the GAL10 gene, encoding UDP-glucose-4-epimerase, another key enzyme in the galactose metabolic pathway (1). Both promoters are induced in the presence of galactose and repressed by glucose through the action of regulatory proteins such as Gal4p and Gal80p. The upstream activating sequences (UAS) located between the two promoters are critical for the activation of both promoters, and Gal4p binds these UAS elements to initiate transcription when galactose is present.
