KEGG   ENZYME: 2.7.1.227
Entry
EC 2.7.1.227                Enzyme                                 
Name
inositol phosphorylceramide synthase;
AUR1 (gene name);
KEI1 (gene name)
Class
Transferases;
Transferring phosphorus-containing groups;
Phosphotransferases with an alcohol group as acceptor
Sysname
1-phosphatidyl-1D-myo-inositol:a very-long-chain (2'R)-2'-hydroxy-phytoceramide phosphoinositoltransferase
Reaction(IUBMB)
1-phosphatidyl-1D-myo-inositol + a very-long-chain (2'R)-2'-hydroxy-phytoceramide = 1,2-diacyl-sn-glycerol + a (4R)-4-hydroxy-N-[(2R)-2-hydroxy-very-long-chain-acyl]-1-O-[(1D-myo-inositol-1-O-yl)hydroxyphosphoryl]sphinganine
Substrate
1-phosphatidyl-1D-myo-inositol [CPD:C01194];
very-long-chain (2'R)-2'-hydroxy-phytoceramide
Product
1,2-diacyl-sn-glycerol [CPD:C00641];
(4R)-4-hydroxy-N-[(2R)-2-hydroxy-very-long-chain-acyl]-1-O-[(1D-myo-inositol-1-O-yl)hydroxyphosphoryl]sphinganine
Comment
The enzyme, characterized from yeast, attaches a phosphoinositol headgroup to alpha-hydroxyphytoceramides, generating a very-long-chain inositol phospho-alpha hydroxyphytoceramide (IPC), the simplest of the three complex sphingolipids produced by yeast.
History
