Nature|新细胞器PXo体的发现：改变我们对细胞磷酸盐运输的理解
Pi（Inorganic phosphate）是无机磷酸盐的简称，它是在生命中普遍的一种重要化合物。生物体需要消耗Pi来进行翻译后修饰和合成必需代谢物。Pi代谢对生命至关重要，其目前的研究主要集中在细菌、酵母和植物中。在细…
Vacuolar H+‐ATPase Is Required for Efficient Vacuolar Phosphate Storage ...
2024年9月18日 · The vacuolar H +-ATPase (V-ATPase) plays a crucial role in facilitating nutrient ions storage in vacuoles, whereas its direct impact on vacuolar phosphate (Pi) accumulation has not been fully elucidated. Previous research revealed that the absence of VPT1 and VPT3, two major vacuolar Pi influx transporters, significantly affected vacuolar Pi ...
Identification of plant vacuolar transporters mediating phosphate storage
2016年3月31日 · Plant vacuoles serve as the primary intracellular compartments for inorganic phosphate (Pi) storage. Passage of Pi across vacuolar membranes plays a critical role in buffering the cytoplasmic Pi level against fluctuations of external Pi and metabolic activities. Here we demonstrate that the SPX-MFS …

Role of vacuoles in phosphorus storage and remobilization
2017年1月11日 · The main storage forms of P include Pi, inositol phosphate (InsP), and polyphosphate (polyP), depending on the organism and tissue. In this review, we summarize the critical role of vacuoles in storage and remobilization of P in different organisms, the importance of vacuolar P storage and remobilization, and the corresponding molecular ...
Metabolic shift of polyphosphate-accumulating organisms with different ...
2012年4月15日 · This work suggests that poly-P storage levels and GAO-like metabolism are important factors affecting the competition between different PAO Types in enhanced biological phosphorus removal systems.
Phosphate-storing organelle discovered in fruit flies - Nature
2023年5月3日 · Inorganic phosphate is an essential mineral for cellular metabolism and signalling. It emerges that a fruit-fly organelle can store this chemical in the form of phospholipids, releasing it in ...
Metabolites of Life: Phosphate - PMC - PubMed Central (PMC)
Phosphates play an important role in the regulation of energy metabolism both by regulating postprandial glucose storage in the muscles and in the liver, as well as the distribution and adaptation of energy metabolites to the needs of the brain and skeletal muscles.
