Transglycosylation of thiamin by fungal beta-N-acetylhexosaminidases

Transglycosylation of thiamin by fungal beta-N-acetylhexosaminidases

A new thiamin glycoside e.g. thiamin beta-D2-deoxy-2-acetamidoglucopyranoside was prepared by transglycosylation by beta-N-acetylhexosaminidase from Aspergillus oryzae and characterized spectrally. Series of other fungal beta-N-acetyl-hexosaminidases from A. awamori A. tamari, A. terreus and Penicil...

Zusammenfassung:A new thiamin glycoside e.g. thiamin beta-D2-deoxy-2-acetamidoglucopyranoside was prepared by transglycosylation by beta-N-acetylhexosaminidase from Aspergillus oryzae and characterized spectrally. Series of other fungal beta-N-acetyl-hexosaminidases from A. awamori A. tamari, A. terreus and Penicillium oxalicum were shown to be able to synthesize the same compound in lower yields
