== Function ==
[https://www.uniprot.org/uniprot/IABF_GEOSE IABF_GEOSE] Involved in the degradation of arabinan and is a key enzyme in the complete degradation of the plant cell wall. Catalyzes the cleavage of terminal alpha-(1->5)-arabinofuranosyl bonds in different hemicellulosic homopolysaccharides (branched and debranched arabinans). It acts preferentially on aryl-alpha-L-arabinofuranosides, and is much less effective on aryl-beta-D-xylopyranosides.<ref>PMID:11943144</ref> <ref>PMID:12221104</ref> <ref>PMID:14517232</ref> <ref>PMID:7887599</ref>
