Current Opinion in Anaesthesiology, 2008
Ethyl pyruvate is a simple derivative of the endogenous metabolite, pyruvic acid. Ethyl pyruvate was shown to ameliorate some of the structural and functional changes associated with mesenteric ischemia and reperfusion in rats.Treatment with ethyl pyruvate has been shown to improve survival and ameliorate organ dysfunction in a wide variety of ...

Human Mutation, 1996
Pyruvate kinase (PK) deficiency due to mutations of the PKLR gene is a common cause of hereditary nonspherocytic hemolytic anemia. Thus far, 55 different mutations have been described in patients with PK-deficient hemolytic anemia. Polymorphisms within the PKLR gene and in the tightly linked glucocerebrosidase (GBA) gene suggest that PK deficiency may ...

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.

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.

Nihon rinsho. Japanese journal of clinical medicine, 1973
PK deficiency is the most common and well characterized erythroenzymopathy in the Embden-Meyerhof glycolytic pathway associated with hereditary hemolytic anemia. History of discovery, clinical features, biochemical studies, as well as recent studies on molecular level were reviewed, with a stress on our own studies. As reference materials, Tables 2 and

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.

Nonenzymatic decarboxylation of pyruvate
Analytical Biochemistry, 1984Triton X-100, retinol, retinoic acid, retinal, hexane, dithiothreitol, mercaptoethanol, and some other commercially available chemicals caused nonenzymatic decarboxylation of pyruvate and alpha-ketoglutarate. "Lipids" obtained from human or pigeon liver homogenates using isopropanol/hexane also had very high nonenzymatic decarboxylating activity on ...

“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.

Pyruvate-Ferredoxin Oxidoreductase
2007Pyruvate decarboxylation in many anaerobic organisms is catalyzed by the thiamine diphosphate (ThDP)-dependent pyruvate–ferredoxin oxidoreductase. We have determined the native structure of this ancient enzyme, as well as of several reaction intermediates, by soaking crystals in a pyruvate-containing solution.

Pyruvate carboxylation in neurons
Journal of Neuroscience Research, 2001AbstractCarboxylation of pyruvate in the brain was for many years thought to occur only in glia, an assumption that formed much of the basis for the concept of the glutamine cycle. It was shown recently, however, that carboxylation of pyruvate to malate occurs in neurons and that it supports formation of transmitter glutamate.
