Plant acetyl-CoA carboxylase.
medium containing [” Plphosphate, the distribution of 32P-labelled acetyl-CoA carboxylase in the fractions can be investigated and it has been found that a greater proportion of the phosphorylated enzyme is present in the polymeric form after exposure of the intact tissue to insulin. Present studies are concerned with investigating whether this polymeric active form is phosphorylated to a great...
متن کاملRegulation of acetyl-coA carboxylase: properties of coA activation of acetyl-coA carboxylase.
Acetyl-CoA carboxylase [acetyl-CoA:carbon-dioxide ligase (ADP-forming), EC 6.4.1.2] is activated by physiological concentrations of CoA. The CoA concentration dependency of this activation is sigmoidal; below 60 microM there is little or no activation, but the activation observed between 60 and 120 microM indicates that small changes in the concentration of CoA can cause significant changes in ...

متن کاملGenetic inhibition of hepatic acetyl-CoA carboxylase activity increases liver fat and alters global protein acetylationa
Lipid deposition in the liver is associated with metabolic disorders including fatty liver disease, type II diabetes, and hepatocellular cancer. The enzymes acetyl-CoA carboxylase 1 (ACC1) and ACC2 are powerful regulators of hepatic fat storage; therefore, their inhibition is expected to prevent the development of fatty liver. In this study we generated liver-specific ACC1 and ACC2 double knock...
متن کاملAssociation between hydrogen peroxide-dependent byproducts of ascorbic acid and increased hepatic acetyl-CoA carboxylase activity.
BACKGROUND Parenteral multivitamin preparation (MVP) induces fatty liver in neonatal guinea pig pups; this is prevented by photoprotection. Photo-excited riboflavin present in MVP generates H(2)O(2) and molecules with masses of 136 and 208. We hypothesized that H(2)O(2) initiates the peroxidation of ascorbic acid (AA), producing biologically active byproducts affecting hepatic lipid metabolism....
