In enzymology a phosphoethanolamine N-methyltransferase (EC 2.1.1.103) is an enzyme that catalyzes the chemical reactionS-adenosyl-L-methionine + ethanolamine phosphate S-adenosyl-L-homocysteine + N-methylethanolamine phosphateThus the two substrates of this enzyme are S-adenosyl methionine and ethanolamine phosphate whereas its two products are S-adenosylhomocysteine and N-methylethanolamine phosphate.This enzyme belongs to the family of transferases specifically those transferring one-carbon group methyltransferases.
