The synthesis of short- and long-chain acylarnitine by etio-chloroplasts of greening barley leaves

Abstract
Etio-chloroplasts of barley, purified on sucrose density gradients were shown to possess carnitine long-chain acyltransferase (carnitine palmitoyltransferase, EC 2.3.1.21) activity and carnitine short-chain acyltransferase (carnitine acetyltransferase EC 2.3.1.7) activity. These enzymes may play a role in the transport of acyl groups as acylcarnitines through the membrane barrier of barley etio-chloroplasts and also ‘or alternatively’ may spare CoA by transferring short- and long-chain acyl groups from short-and long-chain acyl CoA to carnitine.
