Beta-amylase (EC 3.2.1.2, saccharogen amylase, glycogenase, beta amylase, 1,4-alpha-D-glucan maltohydrolase) is an enzyme with system name 4-alpha-D-glucan maltohydrolase.[1][2][3] This enzyme catalyses the following chemical reaction
- Hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive maltose units from the non-reducing ends of the chains
This enzyme acts on starch, glycogen and related polysaccharides and oligosaccharides producing beta-maltose by an inversion.
