Abstract

CoASH, Mg(2+), ATP and (-)-carnitine were found to be essential for the production of palmitoylcarnitine from palmitate by purified barley etio-chloroplasts. It was concluded that long-chain acyl CoA synthetase (palmitoyl CoA synthetase, EC 6.2.1.3) and carnitine long-chain acyl-transferase (carnitine palmitoyltransferase, EC 2.3.1.21) activity were present in the etio-chloroplasts. It is suggested that the long-chain acylcarnitine formed may move more easily through membrane barriers than the long-chain acyl CoA compound. Also or alternatively this enzyme may spare CoA by transferring long-chain acyl groups from long-chain acyl CoA to carnitine.
