생화학적/생리학적 작용

Glucosidase catalyzes the hydrolysis of α-1,4 linkages with a substrate preference for maltose, maltotriose and maltotetraose. Reactivity with large polysaccharides like dextrin and starch have also been described.

Beta-glucosidase was purified from a crude cellulase preparation from Aspergillus niger by affinity chromatography on a methacrylamide-N-methylene-bis-methacrylamide copolymer bearing cellobiamine. The purified enzyme was a dimer with an isoelectric point of 4.0. The molecular mass of the enzyme was estimated

The action patterns of glucoamylase (amyloglucosidase) and glucosyltransferase (transglucosylase) on D-[1-14C]glucose, [1-14C]maltose, and [1-14C]malto-oligosaccharides (labeled at position 1 of the D-glucose group at the reducing end) have been investigated by paper-chromatographic and oligosaccharide-mapping techniques.
