Abstract

The enzyme carnitine acetyltransferase (acetyl-CoA:carnitine O-acetyltransferase, EC 2.3.1.7) has been purified to homogeneity from hepatic mitochondria of clofibrate-fed rats. It is a protein of molecular weight 56 000 composed of two non-identical subunits of molecular weight 34 000 and 25 000. The enzyme is inhibited by palmityl-CoA as well as acetyl carnitine. The inhibition by fatty acyl-CoA is competitive with respect to both the substrates, carnitine and acetyl-CoA. The inhibition by acetylcarnitine is reversed by carnitine but not by acetyl-CoA.
