Biotransformation in Carbohydrate Synthesis. N-Acetylgalactosaminyl Transfer on to Methyl N-Acetyl-β-D-glucosaminide (Methyl 2-Acetamido-2-deoxy-β-D-glucopyranoside) and Methyl N-Acetyl-α-D-glucosaminide (Methyl 2-Acetamido-2-deoxy-α-D-glucopyranoside) Catalysed by a β-N-Acetylga...

Using a crude N-acetylgalactosaminidase from Aspergillus oryzae, the β-N-acetylgalactosaminyl moiety of p-nitrophenyl N-acetylgalactosaminide was transferred to the C-4 and C-6 hydroxy groups of methyl N-acetyl-β-D-glucosaminide and methyl N-acetyl-α-D-glucosaminide and, for the latter, with high efficiency and selectivity for transfer to the C-4 position.
