Aspergillus niger M-1 strain shows strong transglycosylation activity. A gene of it was introduced into Escherichia coli, and isomalto-oligosaccharides were isolated by a chemical enzymatic method in order to measure the transglycosylation activity.

Key words

Aspergillus niger transglycosylation activity protein E. coli transformant isomalto-oligosaccharides
