Activity-dependent adenosine release may be linked to activation of Na+-K+ ATPase : an in vitro rat study [PDF]

open access: yes, 2014
In the brain, extracellular adenosine increases as a result of neuronal activity. The mechanisms by which this occurs are only incompletely understood. Here we investigate the hypothesis that the Na+ influxes associated with neuronal signalling activate ...

Microbial extracellular enzyme activity with simulated climate change

open access: yes, 2022
It is critical to understand the consequences of environmental change for the microbial regulation of carbon and nutrient cycling. Specifically, understanding microbial community traits, such as extracellular enzyme activity, can help inform nutrient ...

The use of phenyl-Sepharose for the affinity purification of proteinases

open access: yes, 1993
Phenyl-Sepharose is most often used as an adsorbent for hydrophobic interaction chromatography (HIC). We report on its effective use for the affinity purification of some extracellular thermostable proteinases from bacterial sources.

The role of extracellular proteases enzyme in bacterial adherence [PDF]

open access: yesمجلة التربية والعلم, 2009
: Extracellular proteases with caseinolytic activities were identified in culture supernatant of several pathogenic bacterial isolates of Staphylococcus aureus and Pseudomonas aeruginosa. Specific activities of these enzymes ranged from 0.27 to 3.89 unit/

Bacillus subtilis Vegetative Catalase Is an Extracellular Enzyme [PDF]

open access: yesApplied and Environmental Microbiology, 1995
Strong catalase activity was secreted by Bacillus subtilis cells during stationary growth phase in rich medium but not in sporulation-inducing medium. N-terminal sequencing indicated that the secreted activity was due to the vegetative catalase KatA, previously considered an endocellular enzyme. Extracellular catalase protected B.

Protein disulfide isomerase activity is essential for viability and extracellular matrix formation in the nematode Caenorhabditis elegans. [PDF]

open access: yes, 2007
Protein disulfide isomerase (PDI) is a multifunctional protein required for many aspects of protein folding and transit through the endoplasmic reticulum.

Extracellular enzyme production and cheating in Pseudomonas fluorescens depend on diffusion rates

open access: yesFrontiers in Microbiology, 2014
Bacteria produce extracellular enzymes to obtain resources from complex chemical substrates, but this strategy is vulnerable to cheating by cells that take up reaction products without paying the cost of enzyme production.

Water availability affects extracellular hydrolytic enzyme production by Aspergillus flavus and Aspergillus parasiticus [PDF]

open access: yes, 2009
The objectives of this study were to examine the effect of different water activities (a(w); 0.99, 0.96 and 0.94) and time (up to 120 h) on quantitative and specific enzyme production during germination and initial growth of Aspergillus flavus and A ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
