摘要：

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