Glucosidase from Aspergillus niger, powder, gray-brown, >=750 U/g

Biochem/physiol Actions

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.
