The Role of Inorganic Polyphosphates in Stress Response and Regulation of Enzyme Activities in Yeastf phosphorus that is consumed by cells with phosphate deficiency. Under phosphate excess, polyP biosynthesis regulates the intracellular phosphate concentration. PolyPs accumulate under conditions of growth suppression under nitrogen starvation and heavy metal toxic stress, and also upon the adaptatharmony 发表于 2025-3-28 23:26:34
Yeast Polyphosphatases PPX1 and PPN1: Properties, Functions, and Localizationare divalent metal ion dependent. PPX1 is an exopolyphosphatase splitting P. from polyP chain end. PPN1 displays exopolyphosphatase and endopolyphosphatase activities in the presence of cobalt and magnesium ions, respectively. PPN1 prefers long-chain polyP, while PPX1 prefers short-chain polyP.

Inorganic Polyphosphates in Mycorrhiza mycelia) and root cortex (intraradical mycelia), take up mineral nutrients, in particular phosphate, from the soil, and deliver to the host. In turn, the host supplies carbon source to the fungi. Phosphate is an essential nutrient for plants, but its diffusion in the soil is slow. Extraradical myceTractable 发表于 2025-3-29 14:57:24
Functions of Inositol Polyphosphate and Inorganic Polyphosphate in Yeast and Amoebalar phosphate homoeostasis is essential to cellular well-being. Key to this regulation of phosphate level is inorganic polyphosphate, a linear polymer of phosphate groups linked by phosphoanhydride bonds. While for many years bacterial research has dominated the inorganic polyphosphate field, intereLATE 发表于 2025-3-29 18:42:13

Role of Inorganic Polyphosphate in the Cells of the Mammalian Brainrough high-energy phosphoanhydride bonds identical to the ones found in ATP. PolyP has also been found in mammalian cells – it is important for blood coagulation, osteoclast function, immune response, etc. In the brain polyP is essential for precise functioning of mitochondria – from significance foAVERT 发表于 2025-3-30 07:58:04
