The importance of the Abn2 calcium cluster in the endo-1,5- arabinanase activity from Bacillus subtilis

Template:ABSTRACT PUBMED 24549757

Function

[EABN2_BACSU] 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 of the alpha-1,5-L-arabinan to produce arabino-oligosaccharides and L-arabinose. It is also active toward linear branched sugar beet arabinan, and pectin from apple.^{[1] [2]}
