In enzymology an initiation-specific alpha-16-mannosyltransferase (EC 2.4.1.232) is an enzyme that catalyzes the chemical reaction in which an alpha-D-mannosyl residue is transferred from GDP-mannose to a lipid-linked oligosaccharide being linked by an alpha-16-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:oligosaccharide 16-alpha-D-mannosyltransferase.
