Sphingomyelin synthase

In enzymology, a sphingomyelin synthase (EC 2.7.8.27) is an enzyme that catalyzes the chemical reaction In enzymology, a sphingomyelin synthase (EC 2.7.8.27) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are ceramide and phosphatidylcholine, whereas its two products are sphingomyelin and 1,2-diacyl-sn-glycerol. This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. The systematic name of this enzyme class is ceramide:phosphatidylcholine cholinephosphotransferase. Other names in common use include SM synthase, SMS1, and SMS2.
