KEGG   ENZYME: 2.7.8.27Help
Entry
EC 2.7.8.27                 Enzyme                                 

Name
sphingomyelin synthase;
SM synthase;
SMS1;
SMS2
Class
Transferases;
Transferring phosphorus-containing groups;
Transferases for other substituted phosphate groups
BRITE hierarchy
Sysname
ceramide:phosphatidylcholine cholinephosphotransferase
Reaction(IUBMB)
a ceramide + a phosphatidylcholine = a sphingomyelin + a 1,2-diacyl-sn-glycerol [RN:R08969]
Reaction(KEGG)
Substrate
ceramide [CPD:C00195];
phosphatidylcholine [CPD:C00157]
Product
sphingomyelin [CPD:C00550];
1,2-diacyl-sn-glycerol [CPD:C00641]
Comment
The reaction can occur in both directions [3]. This enzyme occupies a central position in sphingolipid and glycerophospholipid metabolism [4]. Up- and down-regulation of its activity has been linked to mitogenic and pro-apoptotic signalling in a variety of mammalian cell types [4]. Unlike EC 2.7.8.3, ceramide cholinephosphotransferase, CDP-choline cannot replace phosphatidylcholine as the donor of the phosphocholine moiety of sphingomyelin [2].
