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 ...

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, ...
