Protein pyrophosphorylation by inositol phosphates: a novel post-translational modification in plants? [PDF]

Frontiers in Plant Science
Inositol pyrophosphates (PP-InsPs) are energy-rich molecules harboring one or more diphosphate moieties. PP-InsPs are found in all eukaryotes evaluated and their functional versatility is reflected in the various cellular events in which they take part ...

The intracellular inositol (pyro)phosphate receptor AtSPX1 reciprocally binds to P1BS DNA [PDF]

Nature Communications
The response of plants to phosphate starvation engages PHR (CC-MYB-PHOSPHATE STARVATION RESPONSE) transcription factors that bind to P1BS (GNATATNC) promoter elements of phosphate-starvation induced (PSI) genes. The encoded proteins include single-domain

Metabolism of inositol derivatives by the gut microbiome [PDF]

Gut Microbes
The gut microbiome harbors immense metabolic capacity, much of which is still being uncovered. Recent discoveries have highlighted the ability of gut microbes to metabolize inositol-derived compounds, including free inositols and their phosphorylated ...

Phytase dose-dependent response of kidney inositol phosphate levels in poultry.

PLoS ONE, 2022
Phytases, enzymes that degrade phytate present in feedstuffs, are widely added to the diets of monogastric animals. Many studies have correlated phytase addition with improved animal productivity and a subset of these have sought to correlate animal ...

Accentuating the positive and eliminating the negative: Efficacy of TiO2 as digestibility index marker for poultry nutrition studies

PLoS ONE, 2023
Inert digestibility index markers such as titanium dioxide are universally accepted to provide simple measurement of digestive tract retention and relative digestibility in poultry feeding trials.

A Solanum tuberosum inositol phosphate kinase (StITPK1) displaying inositol phosphate–inositol phosphate and inositol phosphate–ADP phosphotransferase activities [PDF]

FEBS Letters, 2008
We describe a multifunctional inositol polyphosphate kinase/phosphotransferase from Solanum tuberosum, StITPKα (GenBank accession number: EF362784), hereafter called StITPK1. StITPK1 displays inositol 3,4,5,6‐tetrakisphosphate 1‐kinase activity: K m = 27 μM, and V max = 19 nmol min−1 mg−1.

Assigning the Absolute Configuration of Inositol Poly- and Pyrophosphates by NMR Using a Single Chiral Solvating Agent

Biomolecules, 2023
Inositol phosphates constitute a family of highly charged messenger molecules that play diverse roles in cellular processes. The various phosphorylation patterns they exhibit give rise to a vast array of different compounds.

Multiple Inositol Polyphosphate Phosphatase Compartmentalization Separates Inositol Phosphate Metabolism from Inositol Lipid Signaling

Biomolecules, 2023
Multiple inositol polyphosphate phosphatase (MINPP1) is an enigmatic enzyme that is responsible for the metabolism of inositol hexakisphosphate (InsP6) and inositol 1,3,4,5,6 pentakisphosphate (Ins(1,3,4,5,6)P5 in mammalian cells, despite being ...

The Inositol Phosphate System—A Coordinator of Metabolic Adaptability

International Journal of Molecular Sciences, 2022
All cells rely on nutrients to supply energy and carbon building blocks to support cellular processes. Over time, eukaryotes have developed increasingly complex systems to integrate information about available nutrients with the internal state of energy ...
