The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the direction in which it was curated.

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): 79.055954Inferred 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].
