Maximal phosphatidylinositol:ceramide phosphoinositol transferase activity was measured in yeast cells harvested during the exponential phase of growth. The addition of inositol to the growth medium resulted in a twofold increase in IPC synthase activity in cells grown in the presence or absence of exogenous choline. Enzyme activity was not regulated in yeast inositol biosynthesis regulatory mutants by the addition of inositol to the growth medium.
