ENZYME entry: EC 2.4.1.232

Accepted Name
Initiation-specific alpha-1,6-mannosyltransferase.
Alternative Name(s)
Alpha-1,6-mannosyltransferase.
Glycolipid 6-alpha-mannosyltransferase.
Reaction catalysed
Transfers an alpha-D-mannosyl residue from GDP-mannose into lipid-linked oligosaccharide, forming an alpha-(1->6)-D-mannosyl-D-mannose linkage
Cofactor(s)
Mn(2+).
Comment(s)
  • In Saccharomyces cerevisiae, this enzyme catalyzes an essential step in the outer chain elongation of N-linked oligosaccharides.
  • Man(8)GlcNAc and Man(9)GlcNAc are equally good substrates.
