Phosphatidylserine decarboxylase of the Golgi and vacuolar membranes%3B converts phosphatidylserine to phosphatidylethanolamine%3B controls vacuolar membrane phospholipid content by regulating phospholipids in compartments that will eventually give rise to the vacuole%3B loss of Psd2p causes a specific reduction in vacuolar membrane PE levels while total PE levels are not significantly affected
