Abstract
Transgalactosylated derivatives of cyclodextrins (CDs) and glucosyl an d maltosyl CDs (G1- and G2-CDs) were synthesized by alpha-galactosidas es from coffee bean and Mortierella vinacea (M. vinacea). The structur es of the transfer products were analyzed by FAB-mass, C-13-NMR and me thylation. Coffee bean alpha-galactosidase transferred a galactosyl re sidue not only to side chains of G1-CDs and G2-CDs, but also directly to CD rings. M. vinacea alpha-galactosidase transferred a galactosyl r esidue only to side chains of G2-CDs.
