Glyceride-glycerol synthesis from pyruvate. Adaptive changes in phosphoenolpyruvate carboxykinase and pyruvate carboxylase in adipose tissue and liver.
The dicarboxylic acid shuttle in adipose tissue and its role in the conversion of pyruvate to glyceride-glycerol has been studied in rat epididymal fat pads in vitro. Phosphoenolpyruvate carboxykinase and pyruvate carboxylase have also been measured in rat liver and the adaptive response of these enzymes to alterations in diet has been compared to alterations of these enzymes in adipose tissue ...
متن کاملFlux through hepatic pyruvate carboxylase and phosphoenolpyruvate carboxykinase detected by hyperpolarized 13C magnetic resonance.
In the heart, detection of hyperpolarized [(13)C]bicarbonate and (13)CO(2) by magnetic resonance (MR) after administration of hyperpolarized [1-(13)C]pyruvate is caused exclusively by oxidative decarboxylation of pyruvate via the pyruvate dehydrogenase complex (PDH). However, liver mitochondria possess alternative anabolic pathways accessible by [1-(13)C]pyruvate, which may allow a wider diagno...
متن کاملAlteration of growth yield by overexpression of phosphoenolpyruvate carboxylase and phosphoenolpyruvate carboxykinase in Escherichia coli.
Phosphoenolpyruvate and oxaloacetate are key intermediates at the junction between catabolism and biosynthesis. Alteration of carbon flow at these branch points will affect the growth yield and the formation of products. We attempted to modulate the metabolic flow between phosphoenolpyruvate and oxaloacetate by overexpressing phosphoenolpyruvate carboxylase and phosphoenolpyruvate carboxykinase...
متن کاملCoordinate regulation of phosphoenolpyruvate carboxylase and phosphoenolpyruvate carboxykinase by light and CO2 during C4 photosynthesis.
The aim of this study was to investigate the relationship between the phosphorylation and activation states of phosphoenolpyruvate carboxykinase (PEPCK) and to investigate how the phosphorylation states of PEPCK and phosphoenolpyruvate carboxylase (PEPC) are coordinated in response to light intensity and CO(2) concentration during photosynthesis in leaves of the C(4) plant Guinea grass (Panicum...
متن کاملActivating phosphoenolpyruvate carboxylase and phosphoenolpyruvate carboxykinase in combination for improvement of succinate production.
Phosphoenolpyruvate (PEP) carboxylation is an important step in the production of succinate by Escherichia coli. Two enzymes, PEP carboxylase (PPC) and PEP carboxykinase (PCK), are responsible for PEP carboxylation. PPC has high substrate affinity and catalytic velocity but wastes the high energy of PEP. PCK has low substrate affinity and catalytic velocity but can conserve the high energy of P...
