How do metabolic stresses trigger catabolic autophagy for cell survival? A study now reveals that the metabolite sensor Pho81 integrates into and activates the kinase activity of the Atg1 complex for pexophagy triggered by phosphate starvation. This demonstrates the plasticity of the autophagy-initiating Atg1 complex.
