With its high-energy phosphate bonds, adenosine triphosphate (ATP) is the main intracellular energy carrier. It also functions in most signaling pathways, as a phosphate donor or a precursor for cyclic adenosine monophosphate. We show here that inositol pyrophosphates participate in the control of intracellular ATP concentration. Yeasts devoid of inositol pyrophosphates have dysfunctional mitochondria but, paradoxically, contain four times as much ATP because of increased glycolysis. We… CONTINUE READING
