Term Information [More information on beta-amylase activity]

Accession
GO:0016161
Name
beta-amylase activity
Ontology
molecular_function
Synonyms
1,4-alpha-D-glucan maltohydrolase activity, beta amylase activity, saccharogen amylase activity, glycogenase activity
Definition
Catalysis of the reaction: (1,4-alpha-D-glucosyl)(n+1) + H2O = (1,4-alpha-D-glucosyl)(n-1) + alpha-maltose. This reaction is the hydrolysis of 1,4-alpha-glucosidic linkages in polysaccharides so as to remove successive maltose units from the non-reducing ends of the chains. Source: EC:3.2.1.2
