Mass balance status: Marked as unbalanced.

Enzyme Commission Primary Name: β-amylase

Enzyme Commission Synonyms: saccharogen amylase, glycogenase, β amylase, β-amylase, 1,4-α-D-glucan maltohydrolase

Enzyme Commission Summary:
Acts on starch, glycogen and related polysaccharides and oligosaccharides producing β-maltose by an inversion. The term 'β' relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolysed.
