L-Arabinose is a constituent of plant-cell-wall poly-saccharides. It is found in a polymeric form in L-arabinan, in which the backbone is formed by 1,5-a- linked l-arabinose residues that can be branched via 1,2-a- and 1,3-a-linked l-arabinofuranose side chains. AbfB hydrolyses 1,5-a, 1,3-a and 1,2-a linkages in both oligosaccharides and polysaccharides, which contain terminal non-reducing l-arabinofuranoses in side chains [1].

The beta-sandwich fold consists of two anti-parallel beta-sheets with seven and and six strands, respectively. In addition, there are four helices outside of the beta-strands. The beta-sandwich strands are closely packed and curved with a jelly roll topology, creating a small catalytic pocket. The domain catalyses the hydrolysis of alpha-1,2-, alpha-1,3- and alpha-1,5-L-arabinofuranosidic bonds in L-arabinose-containing hemicelluloses such as arabinoxylan and L-arabinan [1].
