Protein
Extracellular exo-alpha-(1->5)-L-arabinofuranosidase ArbA
Organism
Cellvibrio japonicus (strain Ueda107)
Function
Involved in the degradation of arabinan and is a key enzyme in the complete degradation of the plant cell wall. Catalyzes the cleavage of the terminal alpha-(1->5)-arabinofuranosyl bonds of linear arabinan and carboxymethylarabinan to produce almost exclusively arabinotriose.
Similarity
Belongs to the glycosyl hydrolase 43 family.
