SYSTEMATIC NAME
IUBMB Comments
diphosphate phosphohydrolase
Specificity varies with the source and with the activating metal ion. The enzyme from some sources may be identical with EC 3.1.3.1 (alkaline phosphatase) or EC 3.1.3.9 (glucose-6-phosphatase). A form of this enzyme with a molecular mass of about 90 kDa is found in tonoplasts of plants and fungi, where it imports protons from the cytosol into the vacuolar lumen.

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
malfunction
A8MQH1
the fugu5 mutant is defective in AVP1, i.e. vacuolar H+-pyrophosphatase, due to point mutations A709T, A553T, or E272K, and fails to support heterotrophic growth after germination. Exogenous supplementation of succinate or the specific removal of the cytosolic diphosphate by the heterologous expression of the cytosolic inorganic diphosphatase1, IPP1, gene from Saccharomyces cerevisiae rescues fugu5 phenotypes. Compared with the wild-type and AVP1Pro:IPP1 transgenic lines, hypocotyl elongation in the fugu5 mutant is severely compromised in the dark but recovers upon exogenous supply of succinate to the growth media. The peroxisomal beta-oxidation activity, dry seed contents of storage lipids, and their mobilization are unaffected in fugu5

the soluble pyrophosphatasem RNA exists in great copy numbers in cells of Methanosaeta thermophila
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
physiological function

the soluble inorganic diphosphatases recycle the pyrophosphate produced by many biosynthetic reactions, and may play a role in the plant adaptation to phosphorus deficiency
physiological function

P31414
vacuolar H+ -ATPases are a specific class of multisubunit pumps that play an essential role in the generation of proton gradients across eukaryotic endomembranes. The plant proton-pumping inorganic pyrophosphatase functionally complements the vacuolar ATPase transport activity and confers bafilomycin resistance when recombinantly expressed in yeast
