Chemical model for oxaloacetate decarboxylase

Bioinorganic Chemistry, 1974
Abstract Spectroscopic studies on the formation of metal complexes and rate studies on the metal catalyzed decarboxylation of oxaloacetate and its esters indicate that oxaloacetate, in the presence of metal ions, decarboxylates according to the mechanism of Steinberger and Westheimer [9].

Oxaloacetate uptake into rat brain mitochondria and reconstruction of the malate/oxaloacetate shuttle

Biochemical and Biophysical Research Communications, 1984
Reconstruction, using non-synaptosomal rat brain mitochondria, has been made here of the malate/oxaloacetate shuttle, made possible by the occurrence in rat brain mitochondria of a carrier mediated transport for oxaloacetate (Km = 60 microM), sensitive to dicarboxylate analogues and mersalyl, and of the two isoenzymes of malate dehydrogenase.

SOME STUDIES ON TRANSAMINATION WITH OXALOACETATE

Canadian Journal of Biochemistry and Physiology, 1959
The formation of alanine in the transamination of α-amino-n-butyrate and glutamate with oxaloacetate in presence of liver homogenates has been studied. It could be quantitatively explained in terms of pyruvate formed by the decarboxylation of oxaloacetate and subsequent transamination.

The vibrational spectra and structures of dimethyl oxaloacetate and dimethyl oxaloacetate-d2

Spectrochimica Acta Part A: Molecular Spectroscopy, 1986
Abstract The complete vibrational spectra of dimethyl oxaloacetate and dimethyl oxaloacetate-d2 have been recorded and analyzed. The i.r. spectra were recorded at liquid N2 as well as ambient temperature. Tentative vibrational assignments are proposed based on an enol structure in the crystalline phase.

Mitochondrial oxaloacetate decarboxylase from rat liver

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1974
Abstract 1. The occurrence of oxaloacetate decarboxylase (EC 4.1.1.3) in rat liver was confirmed. The decarboxylation was found in both mitochondria and the soluble cytoplasm. 2. The mitochondrial enzyme was partially purified. It appeared not to be activated by divalent cations, nor to be inhibited by chelating agents. It was inhibited up to 50% by

Oxaloacetate inhibition of aconitate hydratase

Biochimica et Biophysica Acta (BBA) - Enzymology, 1969
Abstract An oxaloacetate-Fe 2+ complex has been found to be a potent competitive inhibitor of aconitate hydratase. The requirement for both oxaloacetate and Fe 2+ in this inhibition appears to be absolute.

Permeability of isolated mitochondria to oxaloacetate

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1973
Abstract 1. 1. The transport of oxaloacetate in mitochondria from several sources has been studied. 2. 2. Oxaloacetate is rapidly transported across the membrane of isolated ratliver mitochondria. The V is 80–270 nmoles/min per mg protein at 30 °C. The K m for oxaloacetate is 80–130 μM. 3. 3.

Glutamic Oxaloacetic Transaminase

Archives of Internal Medicine, 1964
It sometimes is difficult to detect myocardial injury in the postoperative patient. The diagnosis is based on the clinical judgment of the examiner plus his interpretation of ancillary aids, including the electrocardiogram and serum glutamic oxaloacetic transaminase (SGOT) values. The usefulness of the SGOT determination during the postoperative period

Oxaloacetate translocator in plant mitochondria

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1985
In plant mitochondria, respiration of NADH linked substrates, such as 2-oxoglutarate or glycine, can be almost totally inhibited by the addition of oxaloacetate, the inhibition being due to reoxidation of the internal NADH by oxaloacetate, as catalyzed by mitochondrial malate dehydrogenase (Walker and Beevers 1956; Woo and Osmond 1976; Journet et al ...

Oxaloacetate decarboxylase from Acetobacter aceti

Archives of Microbiology, 1980
An oxaloacetate (OAA) decarboxylase (EC 4.1.1.3) has been purified 72-fold from Acetobacter aceti cells grown on ethanol, and its molecular weight was estimated to be about 80,000 by gel filtration. Several properties distinguished this enzyme from the OAA decarboxylase from A.
