Rgt1inYeastGlucoseInductionPathway
Yeast sense glucose in their environment and alter gene expression to match their nutritional needs. In a glucose-rich environment, glycolysis is activated, glucose transport is increased and gluconeogenesis repressed to use glucose to make energy. In a glucose-poor environment these processes are regulated in the opposite direction. Rgt1 is a yeast transcription factor that helps to regulate glucose metabolism, resp......阅读全文
