Purification of the β-N-acetylhexosaminidase from Aspergillus oryzae and the β-mannosidases from Helix pomatia and A. oryzae and their application to the enzymic synthesis of the core trisaccharide of the N-linked glycoproteins

Abstract

The β-N-acetylhexosaminidase from Aspergillus oryzae and the β-mannosidases from Helix pomatia and A. oryzae were purified and used to synthesise the core trisaccharide of N-linked glycoproteins, Manp-(1→4)-β-D-GlcpNAc-(1→4)-D-GlcpNAc.
