GGDB:

β1,4-N-Acetylglucosaminyltransferase-II (MGAT2)は、MGAT1が合成したN-型糖鎖構造（Manα1-6(Manα1-3)Manα1-6(GlcNAcβ1-2Manα1-3)Manβ1-4GlcNAcβ1-4GlcNAcβ1-Asn）からマンノシダーゼによりMannoseが2つ除去された糖鎖（Manα1-6(GlcNAcβ1-2Manα1-3)Manβ1-4GlcNAcβ1-4GlcNAcβ1-Asn）に対してb1-2でGlcNAcを転移し、（GlcNAcb1-2Mana1-6(GlcNAcb1-2Mana1-3)Manb1-4GlcNAcb1-4GlcNAcb1-Asn）構造を合成する酵素である。Mgat2欠損マウスは、N-アセチルラクトサミンを含むN型糖鎖の減少を引き起こし、出産後致死である。
