WebGal4 recognizes genes with UAS G, an upstream activating sequence, and activates them. In yeast cells, the principal targets are GAL1 ( galactokinase ), GAL10 ( UDP-glucose 4-epimerase ), and GAL7 ( galactose-1-phosphate uridylyltransferase ), three enzymes required for galactose metabolism. WebWe found that the GAL genes are controlled by a transcriptional cascade. Thus, GAL4, which encodes an activator of the GAL genes, is repressed by MIG1, a zinc finger …
