General Information

General Information Comment Organism
malfunction defects in PPase activity cause severe developmental defects and/or growth arrest in several organisms. The fugu5 mutant phenotype, caused by a defect in H+-PPase activity, shows a postgerminative growth phenotype, but is rescued by complementation with the yeast cytosolic PPase IPP1, overview. Increased cytosolic PPi levels Impaired postgerminative development in fugu5 by inhibiting gluconeogenesis Arabidopsis thaliana
metabolism implication of H+-PPase in postgerminative oilseed metabolism, overview Arabidopsis thaliana
physiological function proton-translocating vacuolar PPase, H+-PPase, uses the energy of diphosphate hydrolysis to acidify the vacuole in higher plants. H+-PPase is a master regulator of cytosolic diphosphate homeostasis, another role of H+-PPase in plants is vacuolar acidification, the role of H+-PPase as a proton-pump is negligible Arabidopsis thaliana
