In enzymology a glycolipid 2-alpha-mannosyltransferase (EC 2.4.1.131) is an enzyme that catalyzes the chemical reaction in which an alpha-D-mannosyl residue is transferred from GDP-mannose to lipid-linked oligosaccharide being attached by an alpha-12-D-mannosyl-D-mannose bond.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases. The systematic name of this enzyme class is GDP-mannose:glycolipid 12-alpha-D-mannosyltransferase.
