MetaCyc Reaction: 3.2.1.88

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

EC Number: 3.2.1.88

Enzymes and Genes:
β-L-arabinopyranosidase Inferred from experiment ( Cajanus cajan )

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: Balanced.

Enzyme Commission Primary Name: non-reducing end β-L-arabinopyranosidase

Enzyme Commission Synonyms: vicianosidase, β-L-arabinosidase (ambiguous), β-L-arabinoside arabinohydrolase (ambiguous)

Standard Gibbs Free Energy (ΔrG in kcal/mol): 79.055954 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
The enzyme, which was characterized from dormant seeds of the plant Cajanus cajan (pigeon pea), removes the terminal non-reducing β-L-arabinopyranoside residue from oligosaccharides. The enzyme retains the original anomeric configuration of the substrate [Dey73].

In the presence of methanol the enzyme demonstrates a transglycosylase activity, transferring the arabinose moiety from it substrate to methanol, generating 1-O-methyl-β-L-arabinopyranose [Dey83].
