ENZYME entry: EC 2.4.1.370

Accepted Name
Inositol phosphorylceramide mannosyltransferase.
Reaction catalysed
GDP-alpha-D-mannose + a very-long-chain inositol phospho-(2'R)-2'-hydroxyphytoceramide <=> a very-long-chain mannosylinositol phospho-(2'R)-2'-hydroxyphytoceramide + GDP
Comment(s)
  • The simplest complex sphingolipid of yeast, inositol-phospho-alpha- hydroxyphytoceramide (IPC), is usually mannosylated to yield mannosyl-inositol-phospho-alpha hydroxyphytoceramide (MIPC).
  • The enzyme is located in the Golgi apparatus, and utilizes GDP-alpha- D-mannose as the mannosyl group donor.
  • It consists of a catalytic subunit (SUR1 or CSH1) and a regulatory subunit (CSG2).
