Kinetics and regulation of the glutamate-aspartate translocator in rat liver mitochondria.
The kinetics and mechanism of the electrogenic exchange of external glutamate with intramitochondrial aspartate have been investigated using aspartateloaded rat liver mitochondria in the absence of metabolism. Apparent kinetic constants were calculated from measured decreases of the mitochondrial matrix aspartate content after glutamate addition by a computer curve fitting procedure and by grap...
متن کاملSelective permeability of rat liver mitochondria to purified aspartate aminotransferases in vitro.
1. A method was devised to allow determination of intramitochondrial aspartate amino-transferase activity in suspensions of intact mitochondria. 2. Addition of purified rat liver mitochondrial aspartate aminotransferase to suspensions of rat liver mitochondria caused an apparent increase in the intramitochondrial enzyme activity. No increase was observed when the mitochondria were preincubated ...
متن کاملTwo forms of aspartate aminotransferase in rat liver and kidney mitochondria.
1. Butan-1-ol solubilizes that portion of rat liver mitochondrial aspartate aminotransferase (EC 2.6.1.1) that cannot be solubilized by ultrasonics and other treatments. 2. A difference in electrophoretic mobilities, chromatographic behaviour and solubility characteristics between the enzymes solubilized by ultrasonic treatment and by butan-1-ol was observed, suggesting the occurrence of two fo...
متن کاملAspartate carbamoyltransferase from rat liver.
1. Aspartate-carbamoyltransferase activity was concentrated from rat-liver preparations. Only l-aspartate, beta-benzyl-l-aspartate and beta-erythro-hydroxy-dl-aspartate were carbamoylated enzymically. The K(m) for l-aspartate and carbamoyl phosphate have been determined by three methods: colorimetric procedure, radioactive assay with [(14)C]aspartate and an assay with [(14)C]carbamoyl phosphate...
متن کاملThe Effect of Resveratrol against Acrolein Toxicity in Mitochondria isolated from Rat Liver
Introduction: Acrolein is an important environmental, food and water pollutant that plays an important role in the development of several diseases. Resveratrol is a phenolic compound with antioxidant properties found in fruits such as grapes, berries and peanuts. The purpose of this study was to evaluate the protective effect of resveratrol in preventing Acrolein-induced toxicity in isolated mi...
