Degradation of polyphosphates by polyphosphate kinases from Ruegeria pomeroyi

Biotechnology Letters, 2014
Polyphosphate kinases 2 (PPK2) are key enzymes for polyphosphate utilisation in bacteria. The genome of Ruegeria pomeroyi, a marine α-proteobacterium, includes three Pseudomonas aeruginosa PPK2 homologs. We expressed these homologs in Escherichia coli as soluble proteins, purified the protein products and compared their metal, pH and nucleotide ...

Detection of Polyphosphates and Enzymes of Polyphosphate Metabolism in Bdellovibrio bacteriovorus

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Mikrobiologie der Landwirtschaft, der Technologie und des Umweltschutzes, 1980
Bdellovibrio bacteriovorus cells, parasitizing in E. coli, contain a considerable amount of inorganic polyphosphates, 55% of the total pool of which is due to the most polymeric acid-insoluble polyphosphates. B. bacteriovorus contains enzymes participating both in the synthesis and consumption of polyphosphates, i.e.

Polyphosphate Chain Stability in Magnesia-Polyphosphate Cements

MRS Proceedings, 1991
ABSTRACTPolyphosphates of the general formula NanH2PnO3n+1·H2O, n = 6, 15, 70, where n is the average degree of polymerization, have been synthesized and characterized by 31P NMR and HPLC. Aqueous solutions of these polyphosphates react at room temperature with magnesia to form cement pastes that harden to amorphous materials. The compressive strengths

Inorganic Polyphosphate and Cancer

Biochemistry (Moscow), 2018
This review presents data on the relationship between inorganic polyphosphate metabolism and carcinogenesis including participation of polyphosphates in the regulation of activity of mTOR and other proteins involved in carcinogenesis, the role of h-prune protein (human polyphosphatase) in cell migration and metastasis formation, the prospects for using

Inorganic polyphosphates in mitochondria

Biochemistry (Moscow), 2010
Current data concerning the crucial role of inorganic polyphosphates (polyP) in mitochondrial functions and dysfunctions in yeast and animal cells are reviewed. Biopolymers with short chain length (approximately 15 phosphate residues) were found in the mitochondria of Saccharomyces cerevisiae. They comprised 7-10% of the total polyP content of the cell.

Methods for Investigation of Inorganic Polyphosphates and Polyphosphate-Metabolizing Enzymes

1999
One of the main reasons for the fact that inorganic polyphosphates were a neglected area of research over a long period of time was the lack of reliable experimental tools for the study of these polymers. In recent years, the range and specificity of the methods available have been revolutionized by the development of novel techniques especially in the

Phosphate, inositol and polyphosphates

Biochemical Society Transactions, 2016
Eukaryotic cells have ubiquitously utilized the myo-inositol backbone to generate a diverse array of signalling molecules. This is achieved by arranging phosphate groups around the six-carbon inositol ring. There is virtually no biological process that does not take advantage of the uniquely variable architecture of phosphorylated inositol. In inositol

Polyphosphate and Phosphate Pump

Annual Review of Microbiology, 2000
▪ Abstract  In microbial cells, inorganic polyphosphate (polyP) plays a significant role in increasing cell resistance to unfavorable environmental conditions and in regulating different biochemical processes. polyP is a polyfunctional compound.
