MetabolomicsStudy on the symbiont preparation of Typha orientalis and polyphosphate bacteria for remediating black-odor water

Currently, significant progress has been made in the management of black-odor water in China. However, some of the water bodies remain at risk of reverting to black and odorous conditions. The mechanisms for rebuilding and sustaining a healthy aquatic ecosystem after the remediation of black-odor...

TranscriptomicsAccumulation of inorganic polyphosphate mediates metabolic downshift and antibiotic tolerance in Mycobacterium tuberculosis
The stringent response, involving the regulatory molecules inorganic polyphosphate (poly P) and (p)ppGpp, is believed to mediate Mycobacterium tuberculosis persistence. In this study, we identified a novel exopolyphosphatase responsible for poly P hydrolysis. Using two different poly P-accumulating ...

ProteomicsMitochondrial inorganic polyphosphate (polyP) is a contributor towards maintaining cellular bioenergetics in SH-SY5Y cells: a proteomics and metabolomics approach
Inorganic polyphosphate (polyP) is an ancestral, ubiquitous, and well-conserved polymer, which is present in all the studied organisms. It is formed by individual subunits of orthophosphate which are linked together by bonds structurally similar and isoenergetic to those found in ATP. While the meta...

MetabolomicsBiosynthesis of polyamine–polyphosphate granules for colitis alleviation

Natural polyamines, such as spermidine and spermine, exert strong anti-inflammatory effects, but their therapeutic benefits are limited by rapid absorption in the small intestine, resulting in low colonic availability. In this study, engineered Citrobacter freundii overexpressing ppk1 (CPP) coul...

TranscriptomicsPolyphosphate affects gene expression and viability of Porphyromonas gingivalis W83
Polyphosphate (polyP) is a ubiquitous and abundant compound found in bacteria, fungi, algae, plant, and animals. Among roles of intracellular polyP in bacteria are resistance and survival in the stationary phase of the growth against stress and stringent condition. Therefore, intracellular polyP is ...

TranscriptomicsHuman inositol polyphosphate multikinase regulates transcript-selective nuclear mRNA export to preserve genome integrity
Messenger (m)RNA export from the nucleus is essential for eukaryotic gene expression. Here, we identify a transcript-selective nuclear export mechanism affecting certain human transcripts, enriched for functions in genome duplication and repair, controlled by inositol polyphosphate multikinase (IPMK...

ProteomicsProteomics on extracellular fractions of polyphosphate accumulating organisms from wastewater treatment plant
Polyphosphate accumulating organisms are responsible for enhanced biological phosphate removal from wastewater, where they grow embedded in a matrix of extracellular polymeric substances. Little is known about the composition and dynamics of those proteins and their production by the different micro...

TranscriptomicsTranscriptome analysis of Escherichia coli mutants involved in inorganic polyphosphate metabolism
Inorganic polyphosphate (Poly P) is a polymer of various phosphate residues linked by phosphoanhydride bonds as in ATP. It is found in all cells in nature with roles in the origin and survival of species, particularly in bacteria. To study the role of the inorganic polyphosphate in bacteria, we obta...
