Substrate specificities

This family of glycoside hydrolases contains β-L-arabinofuranosidase, which was recently established for HypBA1 from Bifidobacterium longum JCM 1217[1]. The enzymes belonging to this family are also members of Pfam DUF1680 family, conserved in many species of bacteria, actinomycetes, fugi, and plants.
