Electron Transfer Precedes ATP Hydrolysis during Nitrogenase Catalysis [PDF]

, 2013
The biological reduction of N2 to NH3 catalyzed by Mo-dependent nitrogenase requires at least eight rounds of a complex cycle of events associated with ATP-driven electron transfer (ET) from the Fe protein to the catalytic MoFe protein, with each ET ...

Principal factors that determine the extension of detection range in molecular beacon aptamer/conjugated polyelectrolyte bioassays. [PDF]

, 2015
A strategy to extend the detection range of weakly-binding targets is reported that takes advantage of fluorescence resonance energy transfer (FRET)-based bioassays based on molecular beacon aptamers (MBAs) and cationic conjugated polyelectrolytes (CPEs).

Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

Targeting the Key Enzymes of Abnormal Fatty Acid β-oxidation as a Potential Strategy for Tumor Therapy

Frontiers in Bioscience-Landmark, 2022
Fatty acid metabolism has attracted extensive attention for its key role in the occurrence and development of tumors. Fatty acids not only participate in the biosynthesis of phospholipids in the membrane to overcome the demand for rapidly proliferating ...

Urinary ATP as an indicator of infection and inflammation of the urinary tract in patients with lower urinary tract symptoms [PDF]

, 2015
BACKGROUND: Adenosine-5'-triphosphate (ATP) is a neurotransmitter and inflammatory cytokine implicated in the pathophysiology of lower urinary tract disease. ATP additionally reflects microbial biomass thus has potential as a surrogate marker of urinary

Extracellular ATP drives systemic inflammation, tissue damage and mortality [PDF]

, 2014
Systemic inflammatory response syndromes (SIRS) may be caused by both infectious and sterile insults, such as trauma, ischemia-reperfusion or burns. They are characterized by early excessive inflammatory cytokine production and the endogenous release of ...
