Identification of Phosphorylation Sites Altering Pollen Soluble Inorganic Pyrophosphatase Activity [PDF]
Protein phosphorylation regulates numerous cellular processes. Identifying the substrates and protein kinases involved is vital to understand how these important posttranslational modifications modulate biological function in eukaryotic cells. Pyrophosphatases catalyze the hydrolysis of inorganic phosphate (PPi) to inorganic phosphate Pi, driving ...

Potato spindle tuber viroid (PSTVd) is a small non-protein-coding RNA pathogen that can induce disease symptoms in a variety of plant species. How PSTVd induces disease symptoms is a long standing question. It has been suggested that PSTVd-derived small RNAs (sRNAs) could direct RNA silencing of a targeted host gene(s) resulting in symptom development.

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

A Novel Polyphosphate-Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii. [PDF]
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

Low soil available phosphorus level reduces cotton fiber length via osmoregulation
IntroductionPhosphorus (P) deficiency hinders cotton (Gossypium hirustum L.) growth and development, seriously affecting lint yield and fiber quality. However, it is still unclear how P fertilizer affects fiber length.MethodsTherefore, a two-year (2019 ...

A novel calcium‐dependent soluble inorganic pyrophosphatase from the trypanosomatid Leishmania major [PDF]
A single‐copy gene IPP encoding a putative soluble inorganic pyrophosphatase (LmsPPase, EC 3.6.1.1) was identified in the genome of the parasite protozoan Leishmania major. The full‐length coding sequence (ca. 0.8 kb) was obtained from genomic DNA by polymerase chain reaction (PCR) and cloned into an Escherichia coli expression vector, and was ...

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

The cytosolic level of inorganic pyrophosphate (PPi) is finely regulated, with PPi hydrolyzed primarily by the vacuolar H+-pyrophosphatase (H+-PPase, VHP1/FUGU5/AVP1) and secondarily by five cytosolic soluble pyrophosphatases (sPPases; PPa1–PPa5) in ...

Orthophosphate – pyrophosphate exchange catalyzed by soluble and membrane‐bound inorganic pyrophosphatases [PDF]
A comparative study of the orthophosphate—pyrophosphate exchange reaction catalyzed by the soluble pyrophosphatase from baker's yeast and by the membrane‐bound pyrophosphatase of Rhodospirillum rubrum chromatophores was performed.In both systems the rate of exchange increased when the pH of the medium was raised from 6.0 to 7.8 and when the MgCl2 ...
