Revisiting yeast trehalose metabolism

Establishing the function of trehalose in yeast cells has led us, over the years, through a long path-from simple energy storage carbohydrate, then a stabilizer and protector of membranes and proteins, through a safety valve against damage caused by oxygen radicals, up to regulator of the glycolytic path. In addition, trehalose biosynthesis has been proposed as a target for novel drugs against several pathogens. Since this pathway is entirely...
