Inhibition by cycloserine of mitochondrial and cytosolic aspartate aminotransferase in isolated rat hepatocytes. 1981

A M Janski, and N W Cornell

Isolated hepatocytes were incubated with L-cycloserine and then treated with digitonin so that mitochondrial and cytosolic fractions were obtained in 5 s. Mitochondrial and total cellular aspartate aminotransferases (EC 2.6.1.1) were inactivated in parallel. The enzyme was also inhibited in isolated mitochondria incubated with L-cycloserine. These results, in contrast with previous reports, indicate that cycloserine reacts equally with mitochondrial and cytosolic aspartate aminotransferases.

D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008297 Male Males
D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.
