A new method of assessing rates of the futile cycle during glycolytic and gluconeogenic metabolism
(1995)
A method for assessing rates of the futile cycle is presented, and it is illustrated in vitro. Glycolytic- and gluconeogenic-type cycles are simulated for the reactions catalyzed by phosphofructokinase (EC 2.7.1.11) and ...
A mutant phosphofructokinase produces a futile cycle during gluconeogenesis in Escherichia coli
(Portland Press Ltd, 1997)
Strains of Escherichia coli bearing different forms of phosphofructokinase were used to assess the occurrence of futile cycling in cell resuspensions supplied with glycerol as gluconeogenic carbon source. A model was used ...
Alzheimer Disease: A New Beginning or a Final Exit?
(Springer, 2005)
Today, a new chapter is being written in the book of Alzheimer disease, one that is challenging the longstanding view that adult neurons are incapable of division, remain nonproliferative, and are terminally differentiated. ...
The potassium battery: a mobile energy source for transport processes in plant vascular tissues
(2017)
Plant roots absorb potassium ions from the soil and transport them in the xylem via the transpiration stream to the shoots. There, in source tissues where sufficient chemical energy (ATP) is available, K+ is loaded into ...
Correlation between citric acid and nitrate metabolisms during CAM cycle in the atmospheric bromeliad Tillandsia pohliana
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2010)
Crassulacean acid metabolism (CAM) confers crucial adaptations for plants living under frequent environmental stresses. A wide metabolic plasticity can be found among CAM species regarding the type of storage carbohydrate, ...
Optimization of the citric acid production by Aspergillus niger through a metabolic flux balance model
(Pontificia Universidad Católica de Valparaíso, 2001)
Una base agroecológica para el diseno de sistemas diversificados de cultivo en el trópico
(CATIE, Turrialba (Costa Rica), 2004)
Los sistemas diversificados de pequeña escala, que utilizan principalmente recursos locales y combinaciones complejas de los cultivos, son relativamente estables y productivos, y presentan rendimientos altos por unidad de ...
The Crystal Complex of Phosphofructokinase-2 of Escherichia coli with Fructose-6-phosphate. Kinetic and structural analysis of the allosteric atp inhibition
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2011-02-18)
Substrate inhibition by ATP is a regulatory feature of the phosphofructokinases isoenzymes from Escherichia coli (Pfk-1 and Pfk-2). Under gluconeogenic conditions, the loss of this regulation in Pfk-2 causes substrate ...
The Crystal Complex of Phosphofructokinase-2 of Escherichia coli with Fructose-6-phosphate KINETIC AND STRUCTURAL ANALYSIS OF THE ALLOSTERIC ATP INHIBITION
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2011)
Substrate inhibition by ATP is a regulatory feature of the phosphofructokinases isoenzymes from Escherichia coli (Pfk-1 and Pfk-2). Under gluconeogenic conditions, the loss of this regulation in Pfk-2 causes substrate ...
In silico and in vivo analysis reveal a novel gene in Saccharomyces cerevisiae trehalose metabolism
(2003-11-13)
Abstract
Background
The ability to respond rapidly to fluctuations in environmental changes is decisive for cell survival. Under these conditions trehalose has an essential ...
