5'-deoxy-5'-isobutylthio-3-deazaadenosine or 5'-deoxy-5'-isobutylthioadenosine inhibited cdp-choline synthesis catalyzed by cholinephosphate cytidylyltransferase ( ctp : cholinephosphate cytidylyltransferase , ec 2.7.7.15 ) and thereby decreased the rate of phosphatidylcholine synthesis from cdp-choline , but did not affect the transmethylation pathway for phosphatidylcholine synthesis .
