title: Regulation of CDP-diacylglycerol synthase activity in Saccharomyces cerevisiae.
abstract: The addition of ethanolamine or choline to inositol-containing growth medium resulted in a reduction of CTP:phosphatidate cytidylyltransferase (CDP-diacylglycerol synthase; EC 2.7.7.41) activity in Saccharomyces cerevisiae. The reduction of activity did not occur in the absence of inositol. CDP-diacylglycerol synthase activity was not regulated in a S. cerevisiae mutant strain (opi1; an inositol biosynthesis regulatory mutant) by the addition of phospholipid precursors to the growth medium.
