Abstract Polyphosphate is a procoagulant inorganic polymer of linear-linked orthophosphate residues. Multiple investigations have established the importance platelet polyphosphate in blood coagulation; however, mechanistic details homeostasis mammalian species remain largely undefined. In this study, xenotropic and polytropic retrovirus receptor 1 (XPR1) regulated platelets was implicated throm...

The polyphosphatase PPN1 of Saccharomyces cerevisiae shows an exopolyphosphatase activity splitting phosphate from chain end and an endopolyphosphatase activity fragmenting high molecular inorganic polyphosphates into shorter polymers. We revealed the compounds switching these activities of PPN1. Phosphate release and fragmentation of high molecular polyphosphate prevailed in the presence of Co...

Here, we provide the dataset associated with our research article on the polyphosphate metabolism entitled, "Multi-level evaluation of Escherichia coli polyphosphate related mutants using global transcriptomic, proteomic and phenomic analyses". By integrating different omics levels (transcriptome, proteome and phenome), we were able to study Escherichia coli polyphosphate mutant strains (Δppk1,...

The volutin granule was isolated from yeast by disruption of freeze-dried cells in an organic solvent and density-gradient-gradient centrifugation. The granule is composed of two types of macromolecule, a linear-chain polyphosphate and four basic proteins, of molecular weights ranging from 10 000 to 20 000. In the dissolved granule these macromolecules are in a complex that is uniform by hydrod...

This study concerns the metabolism of polyphosphate in Trichoderma harzianum, a biocontrol agent with innate resistance against most chemicals used in agriculture, including metals, when grown in the presence of different concentrations of cadmium. The biomass production was affected by the concentration of metal used. Control cultures were able to accumulate polyphosphate under the conditions ...
