Acetyl-coenzyme A
As the major lysosomal degradation pathway, autophagy represents the guardian of cellular homeostasis, removing damaged and potentially harmful material and replenishing energy reserves in conditions of starvation. Given its vast physiological importance, autophagy is crucially involved in the process of aging and associated pathologies. Although the regulation of autophagy strongly depends on ...
متن کاملRegulation of Acetyl-Coenzyme A Carboxylase and Acetyl-Coenzyme A Synthetase in Spinach Chloroplasts
Acetyl-CoA Carboxylase, Acetyl-CoA Synthetase, Light Dependence o f Fatty Acid Synthesis in Chloroplasts In analogy to chloroplast fatty acid synthesis from acetate the key enzymes o f acetate fixation, acetyl-CoA synthetase and acetyl-CoA carboxylase, in rapidly Triton X-100 lysed spinach chloroplasts show an activation by light and deactivation in the dark. The stimulation o f acetyl-CoA carb...
متن کاملCharacterization of Maize Acetyl-Coenzyme A Carboxylase.
Maize (Zea mays L.) leaf acetyl-CoA carboxylase (ACCase) was purified about 500-fold by ammonium sulfate fractionation and gel filtration and blue Sepharose affinity and anion-exchange chromatography. Most ACCase activity (85%) recovered from the anion-exchange column was found in a highly purified fraction (specific activity 5.5 [mu]mol acid-stable product min-1 mg-1) that consisted primarily ...
متن کاملSubstrate specificity of acetyl coenzyme A synthetase.
Acetyl coenzyme A synthetase (EC 6.2.1.1) has been examined for its ability to accept various carboxylic acids as substrates in place of acetic acid. The activity of the enzyme with these substrates was monitored using a coupled enzyme assay and high pressure liquid chromatography (HPLC) analysis. Short chain carboxylic acids were found to be active including: propionic, acrylic, fluoroacetic, ...
متن کاملRat Mammary Acetyl Coenzyme A Carboxylase
The isolation of acetyl-CoA carboxylase from lactating rat mammary glands is described. A procedure was used which differs significantly from those employed by others who have isolated this enzyme from animal tissues. The purified enzyme catalyzes the carboxylation of 5.5 pmoles of acetylCoA per min per mg of protein under optimum assay conditions. Apparent K, values were determined for acetyl-...
