Regulation of pyruvate carboxylase activity by pyruvate in mice liver
International Journal of Biochemistry, 1979Abstract 1. 1. In order to study in vivo the possible regulatory role of pyruvate concentrations on pyruvate carboxylase activity. fed or 24 hr-fasted mice received various overloads of unlabeled pyruvate. 2. 2. The effect of these overloads on the incorporation of [2- 14 C]pyruvate into blood glucose was studied. 3. 3.

Assays of Pyruvate Dehydrogenase Complex and Pyruvate Carboxylase Activity
2011Pyruvate dehydrogenase complex (PDC) and pyruvate carboxylase (PC) are mitochondrial enzymes that provide the initial steps of the two main alternatives for pyruvate metabolism: oxidative decarboxylation vs. anaplerotic carboxylation, gluconeogenesis, and glycerogenesis.

Pyruvate Carboxylase and Pyruvate Dehydrogenase Deficiency
2014Pyruvate carboxylase and pyruvate dehydrogenase deficiency are the most common disorders in pyruvate metabolism and almost always affect the central nervous system. The severity and the clinical phenotypes vary, with a range from overwhelming neonatal lactic acidosis and early death to milder presentations.

Bioelectrocatalysis of Pyruvate with PQQ-dependent Pyruvate Dehydrogenase
ECS Transactions, 2010Although pyruvate has not been considered as a fuel for an enzymatic biofuel cell, there are dehydrogenase enzyme capable of oxidizing pyruvate. This paper details the discovery of a pyrroloquinoline quinone-dependent pyruvate dehydrogenase (PQQ-PDH) in Gluconobacter species.

“Fluorokinase” and pyruvic kinase
Archives of Biochemistry and Biophysics, 1958Abstract 1. 1. The enzyme catalyzing the CO2-dependent phosphorylation of fluoride by adenosine triphosphate to yield monofluorophosphate, an activity referred to as “fluorokinase,” has been isolated in crystalline form from rabbit muscle extracts. The crystalline enzyme has been found to possess considerable pyruvic kinase activity. 2. 2.

Clinical Biochemistry, 1990
Pyruvate kinase (PK) deficiency was initially described by Valentine et al. in 1961. Since then, more than 300 cases have been described, including 65 in Japan. PK deficiency is the most common hereditary nonspherocytic hemolytic anemia among several red cell enzyme defects of the Embden-Meyerhof glycolytic pathway.

Trends in Plant Science
Pyruvate serves as a central node in plant metabolism. Together with its high-energy form, phosphoenolpyruvate (PEP), it links core carbon pathways to the biosynthesis of terpenoids, phenolics, and fatty acids. Specialized cell types in vascular, endosperm, and photosynthetic tissues utilize these precursors to favor the formation of lignin, fatty ...

Disorders of pyruvate metabolism
2013Pyruvate dehydrogenase and pyruvate carboxylase deficiency are the most common disorders in pyruvate metabolism. Diagnosis is made by enzymatic and DNA analysis after basic biochemical tests in plasma, urine, and CSF. Pyruvate dehydrogenase has three main subunits, an additional E3-binding protein and two complex regulatory enzymes.
