Scientists have shown for the first time how specific metabolites produced by autophagy are utilized by a cell. They discovered that in budding yeast adapting to respiratory growth, autophagy — an intracellular recycling system — recycles the amino acid serine to trigger growth through mitochondrial one-carbon metabolism. This study shows how the recycling function of autophagy is crucial for adaptation to fluctuating environmental conditions.
