Synonyms Alg11, Alg2 mannosyltransferase, At2G40190, galactomannan deficiency protein 3, GDP-Man:Man3GlcNAc2-PP-dolichol-alpha1,2-mannosyltransferase, GDP-mannose-oligosaccharide-lipid mannosyltransferase, gmd3, guanosine diphosphomannose-oligosaccharide-lipid mannosyltransferase, hALG11, LEW3, mannosyltransferase, guanosine diphosphomannose-oligosaccharide-lipid, oligosaccharide-lipid mannosyltransferase
EC Number 2.4.1.131
CAS Registry Number 74506-43-7
Comments The biosynthesis of asparagine-linked glycoproteins (N-linked protein glycosylation) utilizes a dolichyl diphosphate-linked glycosyl donor, which is assembled by the series of membrane-bound glycosyltransferases that comprise the dolichol pathway. ALG11 mannosyltransferase from Saccharomyces cerevisiae carries out two sequential steps in the formation of the lipid-linked core oligosaccharide, adding two mannose residues in ¦Á(1¡ú2) linkages to the nascent oligosaccharide.
