Jack bean alpha-mannosidase had a wide acceptor specificity and could transfer mannosyl residues to various acceptors such as D-fructose, L-arabinose, maltose, lactose, and sucrose. The structures of the transferred products of branched cyclodextrins (CDs) (glucosyl-beta CD, maltosyl-alpha CD, and maltosyl-beta CD) were found to be alpha-D-mannosyl-(1-->6)-alpha-D-glucosyl-(1-->6)-beta CD, alpha-D-mannosyl- (1-->6)-alpha-D-glucosyl-(1-->4)-alpha-D-glucosyl-(1-->6)-alpha CD and alpha-D-mannosyl-(1-->6)-alpha-D-glucosyl-(1-->4)-alpha-D-glucosyl-(1--> 6)- beta CD, respectively. Almond alpha-mannosidase also produced the same transmannosylated products of branched CDs.

UI MeSH Term Description Entries
D007887 Fabaceae The large family of plants characterized by pods. Some are edible and some cause LATHYRISM or FAVISM and other forms of poisoning. Other species yield useful materials like gums from ACACIA and various LECTINS like PHYTOHEMAGGLUTININS from PHASEOLUS. Many of them harbor NITROGEN FIXATION bacteria on their roots. Many but not all species of "beans" belong to this family.

D008361 Mannosidases Glycoside hydrolases that catalyze the hydrolysis of alpha or beta linked MANNOSE. Mannosidase
D008362 Mannosides Glycosides formed by the reaction of the hydroxyl group on the anomeric carbon atom of mannose with an alcohol to form an acetal. They include both alpha- and beta-mannosides. Mannoside

D009754 Nuts Botanically, a type of single-seeded fruit in which the pericarp enclosing the seed is a hard woody shell. In common usage the term is used loosely for any hard, oil-rich kernel. Of those commonly eaten, only hazel, filbert, and chestnut are strictly nuts. Walnuts, pecans, almonds, and coconuts are really drupes. Brazil nuts, pistachios, macadamias, and cashews are really seeds with a hard shell derived from the testa rather than the pericarp. Nut
