Poly P links energy and phosphate metabolism in a 'phosphate-energy-network'

Copyright information:Taken from "Systematic screening of polyphosphate (poly P) levels in yeast mutant cells reveals strong interdependence with primary metabolism"Genome Biology 2006;7(11):R109-R109.Published online 15 Nov 2006PMCID:PMC1794592. Enzymatic reactions between the main phosphate/energy pools, ATP and poly P (shown by black arrows) are (at least partly) hypothesized. Flow to different organic phosphate/energy pools is indicated by the gray arrows. In contrast to ATP, poly P is less directly interconnected with the other phosphate pools and, therefore, its levels fluctuate more.
