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, 1980Bdellovibrio 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.

Crystal structure of a polyphosphate kinase and its implications for polyphosphate synthesis [PDF]
EMBO Reports, 2005 Polyphosphate (polyP), a linear polymer of hundreds of orthophosphate residues, exists in all tested cells in nature, from pathogenic bacteria to mammals. In bacteria, polyP has a crucial role in stress responses and stationary-phase survival. Polyphosphate kinase (PPK) is the principal enzyme that catalyses the synthesis of polyP in bacteria.

Inorganic Polyphosphate and Cancer
Biochemistry (Moscow), 2018This 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), 2010Current 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
1999One 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, 2016Eukaryotic 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.

Determination of the size of polyphosphates with polyphosphate glucokinase.
Biochemistry international, 1986A procedure for determining the size of inorganic polyphosphates of chain lengths up to about 750 is described. It involves reducing the size with polyphosphate glucokinase to a chain length that can be accurately determined by polyacrylamide gel electrophoresis.

Interactions of uranium with polyphosphate
Chemosphere, 2007Inorganic polyphosphates (PolyP) are simple linear phosphate (PO(4)(3-)) polymers which are produced by a variety of microorganisms. One of their functions is to complex metals resulting in their precipitation. We investigated the interaction of phosphate and low-molecular-weight PolyP (1400-1900Da) with uranyl ion at various pHs.
