Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage Chains Enzyme Name Description Catalytic Residues alpha-N-arabinofuranosidase
M-CSA #667 Involved in the degradation of arabinan and is a key enzyme in the complete degradation of the plant cell wall. Catalyses 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. It is a member of the glycosyl hydrolase 51 family.
