Term Name:	beta-amylase activity
Synonyms:	4-alpha-D-glucan maltohydrolase activity, beta amylase activity, glycogenase activity, saccharogen amylase 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.
