Kinetic properties of glycerophosphate oxidase isolated from dry baker's yeast
(Elsevier B.V., 2008-06-01)
The glycerophosphate oxidase is a flavoprotein responsible for the catalysis of the oxidation of the glycerophosphate to dihydroxyacetone phosphate, through the reduction of the oxygen to hydrogen peroxide. The glycerophosphate ...
Invertase, glucose oxidase and catalase for converting sucrose to fructose and gluconic acid through batch and membrane-continuous reactors
(Universidade de São Paulo, Faculdade de Ciências Farmacêuticas, 2011)
Conversion of sucrose into fructose and gluconic acid using invertase, glucose oxidase and catalase was studied by discontinuous (sequential or simultaneous addition of the enzymes) and continuous (simultaneous addition ...
Carbon Nanotubes Paste Electrodes. A New Alternative for the Development of Electrochemical Sensors
(Wiley VCH Verlag, 2007-12)
In this work we summarize the recent activities of our group regarding the analytical performance of a new compositematerial, the so-called carbon nanotubes paste electrode (CNTPE) obtained by dispersion of multiwall ...
Angiotensin II induces superoxide generation via NAD(P)H oxidase activation in isolated rat pancreatic islets
(ELSEVIER SCIENCE BV, 2009)
Angiotensin II (Ang II) controls blood pressure, electrolyte balance, cell growth and vascular remodeling. Ang II activates NAD(P)H oxidase in several tissues with important function in the control of insulin secretion. ...
Apparent redundancy of electron transfer pathways via bc(1) complexes and terminal oxidases in the extremophilic chemolithoautotrophic Acidithiobacillus ferrooxidans
Acidithiobacillus ferrooxidans is an acidophilic chemolithoautotrophic bacterium that can grow in the presence of either the weak reductant Fe2+, or reducing sulfur compounds that provide more energy for growth than Fe2+. ...
Sodium nitrite downregulates vascular NADPH oxidase and exerts antihypertensive effects in hypertension
(ELSEVIER SCIENCE INC, 2011)
Dietary nitrite and nitrate are important sources of nitric oxide (NO). However, the use of nitrite as an antihypertensive drug may be limited by increased oxidative stress associated with hypertension. We evaluated the ...
