Substrate activation of pyruvate carboxylase by pyruvate

Biochemical and Biophysical Research Communications, 1969
Abstract A kinetic analysis of pyruvate carboxylase isolated from sheep liver and using pyruvate as the variable substrate revealed non-Michaelis Menten kinetic. Double reciprocal plots were biphasic and R S values of 222 were obtained. Hill plots prepared from the initial velocity data showed that at low pyruvate concentrations, the slope of the ...

Pyruvate carboxylase

The International Journal of Biochemistry & Cell Biology, 1998
Pyruvate carboxylase [EC 6.4.1.1] is a member of the family of biotin-dependent carboxylases and is found widely among eukaryotic tissues and in many prokaryotic species. It catalyses the ATP-dependent carboxylation of pyruvate to form oxaloacetate which may be utilised in the synthesis of glucose, fat, some amino acids or their derivatives and several

Amperometric sensor for pyruvate with immobilized pyruvate oxidase

Analytica Chimica Acta, 1987
Abstract Several procedures for immobilization of pyruvate oxidase by chemical bonding are reported. Attachment to nylon net was unsatisfactory in terms of yield and stability. Polyazetidine, a new commercially available prepolymer and a new nylon membrane with surface carboxyl groups provided good long-term stability, up to 30 days in the case of ...

Disorders of pyruvate carboxylase and the pyruvate dehydrogenase complex

Journal of Inherited Metabolic Disease, 1996
SummaryThe most common defect associated with deficiency of the pyruvate dehydrogenase (PDH) complex occurs in the E1 component, specifically due to mutations in the X‐linked E1α gene. Clinical sequelae of these mutations, which range from severe neonatal lactic acidosis to carbohydrate‐sensitive ataxia, can be different in males and females depending ...

Pyruvate carboxylase deficiency

Journal of Inherited Metabolic Disease, 1984
AbstractThe causes of congenital lactic acidaemia are outlined. Isolated pyruvate carboxylase deficiency is reviewed in detail with a report of a recent case and a discussion of the biochemical consequences. Other causes of defective pyruvate carboxylation are described, particularly the combined carboxylase defects.

Determination of glutamate pyruvate transaminase and pyruvate with an amperometric pyruvate oxidase sensor

Analytica Chimica Acta, 1980
Abstract Pyruvate oxidase (E.C. 1.2.3.3.) is immobilized by adsorption on a porous acetylcellulose membrane, and combined with an oxygen electrode to provide a sensor for pyruvate (0.1–0.8 mM). The response time is 2 min. Glutamate pyruvate transaminase (0.5–180 × 10 -3 I.U. ml -1 ) is determined by its effect on pyruvate production by the alanine—α-

Ethyl pyruvate

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 ...
