Figure 1From: Stability analysis of the GAL regulatory network in Saccharomyces cerevisiae and Kluyveromyces lactisThe galactose signalling pathway. The external galactose signal controls the transcriptional activity of the GAL genes. Galactose can shuttle between the cytoplasm and the nucleus. The galactose bound stage of the protein Gal3p is Gal3p*. The pointed arrows indicate activation whereas the blunt arrows indicate inhibition.Back to article page
