Protein
Intracellular exo-alpha-L-arabinofuranosidase
Gene
asdII
Organism
Bacteroides ovatus
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Involved in the degradation of arabinan and is a key enzyme in the complete degradation of the plant cell wall. Catalyzes the cleavage of terminal alpha-L-arabinofuranosyl residues in different hemicellulosic homopolysaccharides (branched and debranched arabinans) and heteropolysaccharides (arabinoxylans) By similarity.

Catalytic activityi

Hydrolysis of terminal non-reducing alpha-L-arabinofuranoside residues in alpha-L-arabinosides.
