Sphingomyelin synthase

Sphingomyelin synthase

In enzymology, a sphingomyelin synthase (EC number| is an enzyme that catalyzes the chemical reaction

:a ceramide + a phosphatidylcholine ightleftharpoons a sphingomyelin + a 1,2-diacyl-sn-glycerol

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.
