Synthesis of acyl-CoAs by isolated spinach chloroplasts in relation to added CoA and ATP

Abstract

The kinetics of incorporation of [2-14C] acetate into lipids and acyl-CoAs in relation to added CoA and ATP by isolated spinach chloroplasts have been examined. The effect of the concentration of these cofactors on lipid and acyl-CoA synthesis was also studied. In the absence of cofactors, or when only one was present, the incorporation was very low and went mainly into lipids. When both cofactors were present a strong stimulation of both activities occurred. After 25 min, acyl-CoAs were more strongly labeled than lipids and both activities continued linearly for at least 60 min.
