An overview of the yeast glucose signalling and metabolic pathways. Signalling events are indicated in solid black, metabolic reactions in solid grey lines. Dashed black lines imply glucose signals activating the signalling components, dashed grey lines summarise metabolic reactions, e.g. glycolysis and gluconeogenesis. The metabolic pathways synthesising the storage carbohydrates glycogen and trehalose are depicted in detail. † indicates that the deletion mutant is lethal.
