KEGG   ENZYME: 3.2.1.2
Entry
EC 3.2.1.2                  Enzyme                                 
Name
beta-amylase;
saccharogen amylase;
glycogenase;
beta amylase;
1,4-alpha-D-glucan maltohydrolase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
4-alpha-D-glucan maltohydrolase
Reaction(IUBMB)
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
Reaction(KEGG)
(other) R02112 R11262
Comment
Acts on starch, glycogen and related polysaccharides and oligosaccharides producing beta-maltose by an inversion. The term 'beta'' relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolysed.
