1 Different acceptor specificities of two glucuronyltransferases involved in the biosynthesis of HNK-1 carbohydrate. Carbohydrates beta-1,3-glucuronyltransferase 1 Homo sapiens
2 The biosynthesis of HNK-1 carbohydrate is mainly regulated by two glucuronyltransferases (GlcAT-P and GlcAT-S) and a sulfotransferase (HNK-1 ST). Carbohydrates beta-1,3-glucuronyltransferase 1 Homo sapiens
3 To determine how the two glucuronyltransferases are involved in the biosynthesis of the HNK-1 carbohydrate, we prepared soluble forms of GlcAT-P and GlcAT-S fused with the IgG-binding domain of protein A and then compared the enzymatic properties of the two enzymes. Carbohydrates beta-1,3-glucuronyltransferase 1 Homo sapiens
4 To determine how the two glucuronyltransferases are involved in the biosynthesis of the HNK-1 carbohydrate, we prepared soluble forms of GlcAT-P and GlcAT-S fused with the IgG-binding domain of protein A and then compared the enzymatic properties of the two enzymes. Carbohydrates beta-1,3-glucuronyltransferase 1 Homo sapiens
5 These lines of evidence indicate that these two enzymes have significantly different acceptor specificities, suggesting that they may synthesize functionally and structurally different HNK-1 carbohydrates in the nervous system. Carbohydrates beta-1,3-glucuronyltransferase 1 Homo sapiens
