Fine-scale temporal variation in marine extracellular enzymes of coastal southern California

open access: yesFrontiers in Microbiology, 2012
Extracellular enzymes are functional components of marine microbial communities that contribute to nutrient remineralization by catalyzing the degradation of organic substrates.

Inhibition of Extracellular Enzymes Exposed to Cyanopeptides

open access: yesCHIMIA, 2020
Harmful cyanobacterial blooms in freshwater ecosystems produce bioactive secondary metabolites including cyanopeptides that pose ecological and human health risks. Only adverse effects of one class of cyanopeptides, microcystins, have been studied extensively and have consequently been included in water quality assessments.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Studies on the Extracellular Enzymes of Staphylococci

open access: yesNippon Saikingaku Zasshi, 1968
The authors determined the optimal conditions for the lysozyme activity test to identify pathogenic staphylococci from various points of view. Besides, in an attempt to apply this test as a routine method, the usefulness of a modification of this test was checked as to a number of staphylococcal strains freshly isolated from human clinical materials ...

Microbial Necromass and Plant Residue Drive Soil Organic Carbon Restructuring During Reductive Soil Disinfestation

open access: yesAgronomy
Reductive soil disinfestation (RSD) is a promising strategy for mitigating soil degradation and enhancing soil health. While soil organic carbon (SOC) is crucial for soil fertility and climate regulation, the mechanisms underlying its stabilization via ...

Above- and belowground responses to long-term herbivore exclusion

open access: yesArctic, Antarctic, and Alpine Research, 2020
Herbivores can play an important role in determining arctic ecosystem function with effects determined in part by herbivore identity. We examined the impact of long-term (twenty-two years) small and large mammal herbivore exclusion in two arctic plant ...

On Single-Cell Enzyme Assays in Marine Microbial Ecology and Biogeochemistry

open access: yesFrontiers in Marine Science, 2022
Extracellular enzyme activity is a well-established parameter for evaluating microbial biogeochemical roles in marine ecosystems. The presence and activity of extracellular enzymes in seawater provide insights into the quality and quantity of organic ...

Enzyme-Immobilized 3D-Printed Reactors for Online Monitoring of Rat Brain Extracellular Glucose and Lactate

open access: yes, 2016
In this study we constructed a highly sensitive system for in vivo monitoring of the concentrations of rat brain extracellular glucose and lactate. This system involved microdialysis (MD) sampling and fluorescence determination in conjunction with a ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.
