- General Function
- Alpha-l-arabinofuranosidase activity
- Specific Function
- 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.
