Resumen
Glycolysis represents the fundamental metabolic pathway for glucose catabolism across biology, and glycolytic enzymes are amongst the most abundant proteins in cells. Their expression at such levels provides a particular challenge. Here we demonstrate that the glycolytic mRNAs are localized to granules in yeast and human cells. Detailed live cell and smFISH studies in yeast show that the mRNAs are actively translated in granules, and this translation appears critical for the localization. Furthermore, this arrangement is likely to facilitate the higher level organisation and control of the glycolytic pathway. Indeed, the degree of fermentation required by cells seems intrinsically connected to the extent of
mRNA localization to granules. On this basis, we have termed the granules, Core
Fermentation (CoFe) granules. Therefore, glycolytic mRNA granules likely represent a conserved means to maintain high-level co-ordinated enzyme synthesi for a critical metabolic pathway
