| Accepted name: |
non-reducing end α-L-arabinofuranosidase |
| Reaction: |
Hydrolysis of terminal non-reducing α-L-arabinofuranoside residues in α-L-arabinosides. |
| Other name(s): |
arabinosidase (ambiguous); α-arabinosidase; α-L-arabinosidase; α-arabinofuranosidase; polysaccharide α-L-arabinofuranosidase; α-L-arabinofuranoside hydrolase; L-arabinosidase (ambiguous); α-L-arabinanase |
| Systematic name: |
α-L-arabinofuranoside non-reducing end α-L-arabinofuranosidase |
| Comments: |
The enzyme acts on α-L-arabinofuranosides, α-L-arabinans containing (1,3)- and/or (1,5)-linkages, arabinoxylans and arabinogalactans. Some β-galactosidases (EC 3.2.1.23) and β-D-fucosidases (EC 3.2.1.38) also hydrolyse α-L-arabinosides. cf. EC 3.2.1.185, non-reducing end β-L-arabinofuranosidase. |
