KEGG   ENZYME: 2.4.1.232
Entry
EC 2.4.1.232                Enzyme                                 
Name
initiation-specific alpha-1,6-mannosyltransferase;
alpha-1,6-mannosyltransferase;
GDP-mannose:oligosaccharide 1,6-alpha-D-mannosyltransferase;
GDP-mannose:glycolipid 1,6-alpha-D-mannosyltransferase;
glycolipid 6-alpha-mannosyltransferase;
GDP-mannose:oligosaccharide 1,6-alpha-D-mannosyltransferase
Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
Sysname
GDP-mannose:oligosaccharide 6-alpha-D-mannosyltransferase
Reaction(IUBMB)
Transfers an alpha-D-mannosyl residue from GDP-mannose into lipid-linked oligosaccharide, forming an alpha-(1->6)-D-mannosyl-D-mannose linkage
Reaction(KEGG)
(other) R06986(G) R08599(G)
Comment
Requires Mn2+. In Saccharomyces cerevisiae, this enzyme catalyses an essential step in the outer chain elongation of N-linked oligosaccharides. Man8GlcNAc and Man9GlcNAc are equally good substrates.
