Glucan 1,4-alpha-maltohydrolase
From Wikipedia, the free encyclopedia
Glucan 1,4-alpha-maltohydrolase (EC 3.2.1.133, maltogenic alpha-amylase, 1,4-alpha-D-glucan alpha-maltohydrolase) is an enzyme with systematic name 4-alpha-D-glucan alpha-maltohydrolase.[1][2] This enzyme catalyses the following chemical reaction
- hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive alpha-maltose residues from the non-reducing ends of the chains

This enzyme acts on starch and related polysaccharides and oligosaccharides. Maltogenic amylases from Bacillus stearothermophilus,[3] Thermus sp.[4] and Geobacillus thermoleovorans[5] are able to degrade acarbose to glucose and acarviosine-glucose.
