| Comment(s) |
|---|
- The enzyme, found in plants and animals, participates in the
processing of N-glycans in the Golgi apparatus.
- Its action is required before the other
N-acetylglucosaminyltransferases involved in the process (GlcNAcT-II
through VI) can act.
- While the natural substrate (produced by EC 3.2.1.113) is described
here, the minimal substrate recognized by the enzyme is alpha-D-Man-
(1->3)-beta-D-Man-R.
- Formerly EC 2.4.1.51.
