== Function ==
[https://www.uniprot.org/uniprot/ARBA_CELJU ARBA_CELJU] 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.<ref>PMID:12198486</ref> <ref>PMID:15708971</ref> <ref>PMID:9163351</ref>

== Publication Abstract from PubMed ==
Cellvibrio japonicus arabinanase Arb43A hydrolyzes the alpha-1,5-linked L-arabinofuranoside backbone of plant cell wall arabinans. The three-dimensional structure of Arb43A, determined at 1.9 A resolution, reveals a five-bladed beta-propeller fold. Arb43A is the first enzyme known to display this topology. A long V-shaped surface groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller. Three carboxylates deep in the active site groove provide the general acid and base components for glycosidic bond hydrolysis with inversion of anomeric configuration.

Cellvibrio japonicus alpha-L-arabinanase 43A has a novel five-blade beta-propeller fold.,Nurizzo D, Turkenburg JP, Charnock SJ, Roberts SM, Dodson EJ, McKie VA, Taylor EJ, Gilbert HJ, Davies GJ Nat Struct Biol. 2002 Sep;9(9):665-8. PMID:12198486<ref>PMID:12198486</ref>
