Inorganic Pyrophosphatases: Study of Interest
(Scientific Research Publishing, 2017)
Inorganic pyrophosphatases are enzymes that catalyze the hydrolysis of inorganic pyrophosphate to orthophosphate. These enzymes are divided into two groups: the soluble pyrophosphatases and the membrane pyrophosphatases. ...

Vacuolar H+-Pyrophosphatase AVP1 is Involved in Amine Fungicide Tolerance in Arabidopsis thaliana and Provides Tridemorph Resistance in Yeast
(Frontiers Media, 2016)
Amine fungicides are widely used as crop protectants. Their success is believed to be related to their ability to inhibit postlanosterol sterol biosynthesis in fungi, in particular sterol-Δ8,Δ7-isomerases and sterol-Δ14- ...

Widespread occurrence of non-phosphorylating glyceraldehyde-3-phosphate dehydrogenase among gram-positive bacteria
(Sociedad Española de Microbiología, 2005)
The non-phosphorylating glyceraldehyde 3-phosphate dehydrogenase (GAPDHN, NADP+-specific, EC 1.2.1.9) is present in green eukaryotes and some Streptococcus strains. The present report describes the results of activity and ...

N-terminal chimaeras with signal sequences enhance the functional expression and alter the subcellular localization of heterologous membrane-bound inorganic pyrophosphatases in yeast
(Portland Press, 2010)
Expression of heterologous multispanning membrane proteins in Saccharomyces cerevisiae is a difficult task. Quite often, the use of multicopy plasmids where the foreign gene is under the control of a strong promoter does ...

Functional complementation of an Escherichia coli gap mutant supports an amphibolic role for NAD(P)-dependent glyceraldehyde-3-phosphate dehydrogenase of Synechocystis sp. strain PCC 6803
(American Society for Microbiology, 1997)
The gap-2 gene, encoding the NAD(P)-dependent D-glyceraldehyde-3-phosphate dehydrogenase (GAPDH2) of the cyanobacterium Synechocystis sp. strain PCC 6803, was cloned by functional complementation of an Escherichia coli ...

Functional complementation of yeast cytosolic pyrophosphatase by bacterial and plant H -translocating pyrophosphatases
(National Academy of Sciences, 2002)
Two types of proteins that hydrolyze inorganic pyrophosphate (PPi), very different in both amino acid sequence and structure, have been characterized to date: soluble and membrane-bound proton-pumping pyrophosphatases ...

Descripción ultraestructural de Euglena pailasensis (Euglenozoa) del Volcán Rincón de la Vieja, Guanacaste, Costa Rica
(Universidad de Costa Rica, 2004)
The euglenoids are unicellular eukaryotic flagellates living in a diversity of soils and aquatic environments and ecosystems. This study describes the ultrastructure of an euglenoid isolated from the surface of a boiling ...

Differential regulation of soluble and membrane-bound inorganic pyrophosphatases in the photosynthetic bacterium Rhodospirillum rubrum provides insights into pyrophosphate-based stress bioenergetics
(American Society for Microbiology, 2004)
Soluble and membrane-bound inorganic pyrophosphatases (sPPase and H -PPase, respectively) of the purple nonsulfur bacterium Rhodospirillum rubrum are differentially regulated by environmental growth conditions. Both ...

Enzymatic systems of inorganic pyrophosphate bioenergetics in photosynthetic and heterotrophic protists: remmants or metabolic cornerstones?
(Springer, 2001)
An increasing body of biochemical and genetic evidence suggests that inorganic pyrophosphate (PPi) plays an important role in protist bioenergetics. In these organisms, two types of inorganic pyrophosphatases [EC 3.6.1.1, ...
