Abstract excerpt
Loss of the major isoform of phosphoglucomutase (PGM) causes an accumulation of glucose 1-phosphate when yeast cells are grown with galactose as the carbon and energy source. Remarkably, the pgm2Delta strain also exhibits a severe imbalance in intracellular Ca(2+) homeostasis when grown under these conditions. In the present study, we examined how the pgm2Delta mutation alters yeast Ca(2+) homeostasis in greater...
