Abstract
Jack bean alpha-mannosidase had a wide acceptor specificity and could transfer mannosyl residues to various accepters such as D-fructose, L- arabinose, maltose, lactose, and sucrose. The structures of the transf erred products of branchd cyclodextrins (CDs) (glucosyl-beta CD, malto syl-alpha CD, and maltosyl-beta CD) were found to be a-D-mannosyl-(1-- >6)-alpha-D-glucosyl-(1-->6)-beta CD, -D-glucosyl-(1-->4)-alpha-D-gluc osyl-(1-->6)-alpha CD and a-D-glucosyl-(1-->4)-alpha-D-glucosyl-(1-->6 )-beta CD, respectively. Almond alpha-mannosidase also produced the sa me transmannosylated products of branched CDs.
