Synthesis of CDP-diglyceride from phosphatidylinositol and CMP

A reaction in which CDP-diglyceride and inositol are formed from 1-stearoyl, 2-arachidonoyl phosphatidylinositol and CMP occurs readily in dialyzed microsomal preparations from the mouse pancreas. The reaction is Mn 2+-dependent, and it is inhibited by each of the two products, CDP-diglyceride and m...

Zusammenfassung:A reaction in which CDP-diglyceride and inositol are formed from 1-stearoyl, 2-arachidonoyl phosphatidylinositol and CMP occurs readily in dialyzed microsomal preparations from the mouse pancreas. The reaction is Mn 2+-dependent, and it is inhibited by each of the two products, CDP-diglyceride and myoinositol. It is presumed to involve the back-reaction of CDP-diglyceride: inositol phosphatidyltransferase (phosphatidyl-inositol synthetase, EC.2.7.8.11.)
