The H+-Translocating Inorganic Pyrophosphatase From Arabidopsis thaliana Is More Sensitive to Sodium Than Its Na+-Translocating Counterpart From Methanosarcina mazei

Frontiers in Plant Science, 2020
Overexpression of membrane-bound K+-dependent H+-translocating inorganic pyrophosphatases (H+-PPases) from higher plants has been widely used to alleviate the sensitivity toward NaCl in these organisms, a strategy that had been previously tested in ...

Self-incompatibility in Papaver targets soluble inorganic pyrophosphatases in pollen

Nature, 2006
In higher plants, sexual reproduction involves interactions between pollen and pistil. A key mechanism to prevent inbreeding is self-incompatibility through rejection of incompatible ('self') pollen. In Papaver rhoeas, S proteins encoded by the stigma interact with incompatible pollen, triggering a Ca2+-dependent signalling network resulting in pollen ...

Comparative biochemical and functional studies of family I soluble inorganic pyrophosphatases from photosynthetic bacteria [PDF]

The FEBS Journal, 2007
Soluble inorganic pyrophosphatases (inorganic diphosphatases, EC 3.6.1.1) were isolated and characterized from three phylogenetically diverse cyanobacteria − Synechocystis sp. PCC 6803, Anabaena sp. PCC 7120, and Pseudanabaena sp. PCC 6903 – and one anoxygenic photosynthetic bacterium, Rhodopseudomonas viridis (purple nonsulfur).

Studies on the biosynthesis of cholesterol: XII. synthesis of allyl pyrophosphates from mevalonate and their conversion into squalene with liver enzymes*

Journal of Lipid Research, 1960
The biosynthesis of allyl pyrophosphates (the pyrophosphates of dimethylallyl alcohol, geraniol, and of farnesol) from dl-mevalonate-2-C14 and from (-)5-phosphomevalonate-2-C14 with soluble liver enzymes in the presence of ATP and Mg++ is described.

Evidence for the role of vacuolar soluble pyrophosphatase and inorganic polyphosphate in Trypanosoma cruzi persistence [PDF]

Molecular Microbiology, 2013
SummaryTrypanosoma cruzi infection leads to development of a chronic disease but the mechanisms that the parasite utilizes to establish a persistent infection despite activation of a potent immune response by the host are currently unknown. Unusual characteristics of T.

Biolistics transformation of callus and cell suspension cultures of Capsicum annuum L. ‘Serrano’ is useful for in vitro studies of the relative contents of secondary metabolites

Acta Agrobotanica, 2019
Capsicum annuum is a crop species of economic importance able to produce capsaicinoids, capsinoids, and pigments with nutritional and medicinal value. Methods to propagate and transform this species have been reported, but most are phenotype dependent ...

Inorganic pyrophosphatase in uncultivable hemotrophic mycoplasmas: identification and properties of the enzyme from Mycoplasma suis

BMC Microbiology, 2010
Background Mycoplasma suis belongs to a group of highly specialized hemotrophic bacteria that attach to the surface of host erythrocytes. Hemotrophic mycoplasmas are uncultivable and the genomes are not sequenced so far.

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

Synthesis of pyrophosphate by chromatophores of Rhodospirillum rubrum in the light and by soluble yeast inorganic pyrophosphatase in water-organic solvent mixtures [PDF]

European Journal of Biochemistry, 1985
Chromatophores of Rhodospirillum rubrum contain a membrane-bound pyrophosphatase that synthesizes pyrophosphate when an electrochemical H+ gradient is formed across the chromatophore membrane upon illumination. In this report it is shown that MgCl2 and Pi have different effects on the synthesis of pyrophosphate in the light depending on whether initial
