H+-Translocating Membrane-Bound Pyrophosphatase from Rhodospirillum rubrum Fuels Escherichia coli Cells via an Alternative Pathway for Energy Generation

open access: yesMicroorganisms, 2023
Inorganic pyrophosphatases (PPases) catalyze an essential reaction, namely, the hydrolysis of PPi, which is formed in large quantities as a side product of numerous cellular reactions.

The inorganic pyrophosphatase activity of erythrocytes in favism

open access: yesThe Turkish Journal of Pediatrics, 1961
Inorganic pyrophosphatase activity of erythrocytes was found to be decreased in subjects affected by the glucose-6-phosphate dehydrogenase deficiency. During the acute hemolytic episode of favism, pyrophosphatase activity shows a further critical fall.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates. [PDF]

open access: yesFEBS Lett
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Escherichia coli DnaE Polymerase Couples Pyrophosphatase Activity to DNA Replication. [PDF]

open access: yesPLoS ONE, 2016
DNA Polymerases generate pyrophosphate every time they catalyze a step of DNA elongation. This elongation reaction is generally believed as thermodynamically favoured by the hydrolysis of pyrophosphate, catalyzed by inorganic pyrophosphatases.

Mutagenesis Reveals That the OsPPa6 Gene Is Required for Enhancing the Alkaline Tolerance in Rice

open access: yesFrontiers in Plant Science, 2019
Alkaline stress (AS) is one of the abiotic stressful factors limiting plant’s growth and development. Inorganic pyrophosphatase is usually involved in a variety of biological processes in plant in response to the abiotic stresses.

PPA1, an energy metabolism initiator, plays an important role in the progression of malignant tumors

open access: yesFrontiers in Oncology, 2022
Inorganic pyrophosphatase (PPA1) encoded by PPA1 gene belongs to Soluble Pyrophosphatases (PPase) family and is expressed widely in various tissues of Homo sapiens, as well as significantly in a variety of malignancies.

Inactivation of yeast inorganic pyrophosphatase by organic solvents

open access: yesAnais da Academia Brasileira de Ciências, 2004
A number of application for enzymes in organic solvents have been developed in chemical processing, food related conversions and analyses. The only unsolved problem related to nonaqueous enzymology is the notion that enzymes in organic solvent are mostly

Reconstitution of Biological Molecular Generators of Electric Current Inorganic Pyrophosphatase

open access: yes, 2020
Proteoliposomes have been reconstituted from soy‐bean phospholipids (asolectin) and inorganic pyrophosphatase isolated from Rhodospirillum rubrum chromatophores.

Enhancement of the rate of pyrophosphate hydrolysis by nonenzymatic catalysts and by inorganic pyrophosphatase. [PDF]

open access: yesJ Biol Chem, 2011
To estimate the proficiency of inorganic pyrophosphatase as a catalyst, 31P NMR was used to determine rate constants and thermodynamics of activation for the spontaneous hydrolysis of inorganic pyrophosphate (PPi) in the presence and absence of Mg2+ at ...
