Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Fluorescence spectroscopy applied to the optimisation of a desalting step by electrodialysis for the characterisation of marine organic matter [PDF]

, 2009
The isolation and characterisation of marine dissolved organic matter (DOM) are still not readily achieved today. The study of this chemically complex material is particularly difficult, especially as it is hindered by the high salinity of seawater.

Inhibition and Interactions of Campylobacter jejuni from Broiler Chicken Houses with Organic Acids

Microorganisms, 2019
Campylobacter jejuni is a bacterium that causes major diarrheal disease worldwide and is also one of the top five foodborne pathogens encountered in the United States. Poultry is a major source of C.

Correlation between bacterial communities and organic acids in the fermentation stage of traditional Chinese sour porridge

International Journal of Food Properties, 2020
Fermented porridge is usually made though the process of natural fermentation of grains with higher starch. Organic acids are the main flavor compounds in fermented porridge. However, the understanding of the correlation between the microbial communities

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

The role of root-released organic acids and anions in phosphorus transformations in a sandy loam soil from Yantai, China

, 2012
One mechanism by which plants can mobilize organic and inorganic forms of phosphorus (P) in soils is by exudation of low-molecular-weight organic acids and anions. However, little is known about their effects on the transformation of P fractions in soils.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Modeling the adsorption of weak organic acids on goethite : the ligand and charge distribution model

, 2001
A detailed study is presented in which the CD-MUSIC modeling approach is used in a new modeling approach that can describe the binding of large organic molecules by metal (hydr)oxides taking the full speciation of the adsorbed molecule into account ...

Relating hygroscopicity and composition of organic aerosol particulate matter [PDF]

, 2010
A hygroscopicity tandem differential mobility analyzer (HTDMA) was used to measure the water uptake (hygroscopicity) of secondary organic aerosol (SOA) formed during the chemical and photochemical oxidation of several organic precursors in a smog chamber.
