Extracellular endo-alpha-(1->5)-L-arabinanase

UniProtKB accession:  A5IKD4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the degradation of arabinan and is a key enzyme in the complete degradation of the plant cell wall. Catalyzes the internal cleavage of alpha-(1->5)-L-arabinofuranosyl residues in different arabinan-containing polysaccharides, and releases arabinotriose and arabinobiose as end products. It acts on branched arabinan (from sugar beet), but more slowly when compared to linear or debranched arabinan.
