RETRACTED: Pyrophosphate modulates plant stress responses via SUMOylation
eLife, 2019 Pyrophosphate (PPi), a byproduct of macromolecule biosynthesis is maintained at low levels by soluble inorganic pyrophosphatases (sPPase) found in all eukaryotes. In plants, H+-pumping pyrophosphatases (H+-PPase) convert the substantial energy present in

Stabilization of Tc-99m radiopharmaceuticals by chemical additives [PDF]
Journal of the Serbian Chemical Society, 2001 The reliability and applicability of the preparation of the three, for nuclear medicine very important, 99mTc-radiopharmaceuticals from the inactive (technetium-cold) kit solutions were tested.

Journal of Biological Chemistry, 1985 (1R)-1-3H-labeled and (1S)-1-3H-labeled geranyl pyrophosphate and neryl pyrophosphate were prepared from the corresponding 1-3H-labeled aldehydes by a combination of enzymatic and synthetic procedures. Following admixture with the corresponding 2-14C-labeled internal standard, each substrate was converted to (+)-bornyl pyrophosphate and (-)-bornyl ...

Treatment with pyrophosphate inhibits uremic vascular calcification [PDF]
, 2011 Pyrophosphate, which may be deficient in advanced renal failure, is a potent inhibitor of vascular calcification. To explore its use as a potential therapeutic, we injected exogenous pyrophosphate subcutaneously or intraperitoneally in normal rats and ...

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Oxidative Phosphorus Chemistry Perturbed by Minerals
Life, 2022 Life is a complex, open chemical system that must be supported with energy inputs. If one fathoms how simple early life must have been, the complexity of modern-day life is staggering by comparison. A minimally complex system that could plausibly provide

Biosynthesis of Thiamin Pyrophosphate [PDF]
EcoSal Plus, 2009 The biosynthesis of thiamin pyrophosphate (TPP) in prokaryotes, as represented by the Escherichia coli and the Bacillus subtilis pathways, is summarized in this review. The thiazole heterocycle is formed by the convergence of three separate pathways.

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

The crystal structure of KScP2O7
Acta Crystallographica Section E: Crystallographic Communications, 2020 Single crystals of KScP2O7, potassium scandium diphosphate, were grown in a borate flux. The title compound crystallizes isotypically with KAlP2O7 in space-group type P21/c, Z = 4.
