Sensitivity of carnitine acyltransferase I to malonly-CoA inhibition in isolated rat liver mitochondria is quantitatively related to hepatic malonyl-CoA concentration in vivo
Abstract
The sensitivity of carnitine acyltransferase I (EC 2.3.1.21) activity to malonyl-CoA inhibition in rat liver mitochondria isolated from animals in various physiological states was quantitatively proportional to the hepatic malonyl-CoA concentration in vivo. It is suggested that this relationship between the two parameters could result in a potent amplification mechanism for the reciprocal regulation of fatty acid synthesis and oxidation.
