title: Specific requirement of lysophosphatidylcholine for palmitoyl-CoA synthetase of chicken intestine.
abstract: The presence of palmitoyl-CoA synthetase (EC 6.2.1.3) in the brush border-free particulate fraction of chicken intestinal mucosa is demonstrated. The enzyme was dependent on the simultaneous presence of lysophosphatidylcholine and Triton X-100 as well as ATP, CoA and Mg2+ for maximal activity. Lysophosphatidylcholine could not be replaced by other lipids. Enzyme preparations solubilized by Triton X-100 or lysophosphatidylcholine were still dependent on the presence of detergents for maximal activity.
