MetaCyc Reaction: 3.2.1.2

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 3.2.1.2

Enzymes and Genes:
β-amylase Inferred by curator : BAM3 ( Arabidopsis thaliana col )

In Pathway: starch degradation II

Note that this reaction equation differs from the official Enzyme Commission reaction equation for this EC number, which can be found here .

Reaction Locations: chloroplast stroma

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

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.
