| Comment(s) |
|---|
- The formation of N-glycosidic linkages of glycoproteins involves the
ordered assembly of the common Glc(3)Man(9)GlcNAc(2) core-
oligosaccharide on the lipid carrier dolichyl diphosphate.
- Early mannosylation steps occur on the cytoplasmic side of the
endoplasmic reticulum with GDP-Man as donor, the final reactions from
Man(5)GlcNAc(2)-PP-dolichol to Man(9)Glc-NAc(2)-PP-dolichol on the
lumenal side use dolichyl beta-D-mannosyl phosphate.
- Formerly EC 2.4.1.130.
