Structural basis of oligosaccharide processing by glycosaminoglycan sulfotransferases.

abstract：:To investigate the developmental role of complex N-linked oligosaccharides, we previously inactivated the mouse Mgat1 gene which encodes UDP-N-acetylglucosamine: alpha-3-D-mannoside beta-1,2-N-acetylglucosaminyltransferase I (GlcNAc-TI). Mgat1-null embryos developed morphogenic abnormalities by embryonic day (E) 9.5 a...
