In enzymology, a phosphatidylcholine synthase (EC 2.7.8.24) is an enzyme that catalyzes the chemical reaction
- CDP-diacylglycerol + choline CMP + phosphatidylcholine
Thus, the two substrates of this enzyme are CDP-diacylglycerol and choline, whereas its two products are CMP and phosphatidylcholine.
This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is CDP-diacylglycerol:choline O-phosphatidyltransferase. This enzyme is also called CDP-diglyceride-choline O-phosphatidyltransferase. This enzyme participates in glycerophospholipid metabolism.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
