Metabolism of Phospholipids in Nocardia polychromogenes

Summary: The rates of synthesis and breakdown of phospholipids in growing cultures of Nocardia polychromogenes were investigated by means of a pulse-labelling technique using 32PO4 3-. The results indicated that phospholipids were broken down and phosphatidylinositol mannosides had a high turnover rate. The other two main components, cardiolipin and phosphatidylethanolamine, had a relatively low rate of turnover.
