GLY-13 plays an important role in the synthesis of N-glycans. Synthesis of paucimannose N-glycans by Caenorhabditis elegans requires prior actions of UDP-N-acetyl-D-glucosamine:alpha-3-D-mannoside beta1,2-N-acetylglucosaminyltransferase I, alpha3,6-mannosidase II and a specific membrane-bound beta-N-acetylglucosaminidase |
| 2.4.1.101 | more |
the enzyme catalyzes the first step in the conversion of oligomannose to complex or hybrid N-glycans of glycoproteins |
| 2.4.1.101 | more |
the enzyme is essential for processing of high-mannose to hybrid and complex N-glycans |
| 2.4.1.101 | more |
transformant plants that exhibit specific reduction of GnTI activity below detection limit, do not exhibit significantly altered complex N-glycan structures. Even the undetectable residual GnTI activity is sufficient for the synthesis of complex N-glycans comparable to wild-type plants |
