Polyphosphates and Complement Activation [PDF]

Frontiers in Medicine, 2019
To sustain life in environments that are fraught with risks of life-threatening injury, organisms have developed innate protective strategies such that the response to wounds is rapid and localized, with the simultaneous recruitment of molecular ...

Adenosine triphosphate as a modulator of protein interactions and stability. [PDF]

FEBS Open Bio
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 ...

Polyphosphate and acidocalcisomes [PDF]

Biochemical Society Transactions, 2016
Inorganic polyphosphate (polyP) accumulates in acidocalcisomes, acidic calcium stores that have been found from bacteria to human cells. Proton pumps, such as the vacuolar proton pyrophosphatase (V-H+-PPase or VP1), the vacuolar proton ATPase (V-H+-ATPase) or both, maintain their acidity.

Antimicrobial Effect of Low-Fluoride Toothpastes Containing Polyphosphate and Polyols: An In Vitro Assessment of Inhibition Zones

Antibiotics, 2023
This study evaluated the antimicrobial effect of toothpastes containing 200 ppm fluoride (200F), xylitol (X, 16%), erythritol (E, 4%), and sodium trimetaphosphate (TMP, 0.25%), alone or in different associations, against Streptococcus mutans (SM ...

Integrated use of polyphosphate and P-solubilizing bacteria enhanced P use efficiency and growth performance of durum wheat

Frontiers in Microbiology, 2023
Coupling phosphate-solubilizing bacteria (PSB) with P fertilizers, including polyphosphates (PolyP), was reported as eco-efficient approach to enhance P use efficiency.

Control of vertebrate skeletal mineralization by polyphosphates. [PDF]

PLoS ONE, 2009
BACKGROUND:Skeletons are formed in a wide variety of shapes, sizes, and compositions of organic and mineral components. Many invertebrate skeletons are constructed from carbonate or silicate minerals, whereas vertebrate skeletons are instead composed of ...

The chemistry of branched condensed phosphates

Nature Communications, 2021
The “anti-branching rule”, introduced in 1950, excludes branched polyphosphates from biological relevance due to their supposedly rapid hydrolysis.

Bacterial polyphosphates interfere with the innate host defense to infection

Nature Communications, 2020
Production of polyphosphate polymers is a ubiquitous trait of bacteria. Here, the authors investigate the role of bacterial long polyphosphates in host immune suppression and show that long polyphosphates produced by E.

Comparison of cITP and 31 P NMR Methods for Determination of Polyphosphates in Meat Product and Sea Fruits

Czech Journal of Food Sciences, 2009
Phosphates are widely used as additives in different kinds of food, including meat, poultry and seafood. These ions work synergistically with salt and allow meat processors to achieve equivalent water-holding capacity with reduced amounts of salt ...

Polyphosphate/platelet factor 4 complexes can mediate heparin-independent platelet activation in heparin-induced thrombocytopenia

Blood Advances, 2016
: Heparin-induced thrombocytopenia (HIT) is a thrombotic disorder initiated by antibodies to complexes between platelet factor 4 (PF4) and heparin. The risk of recurrent thromboembolism persists after heparin is cleared and platelet activation leading to
