Enzyme Commission Number
EC 3.2.1.55
Product Overview
High-quality enzyme products. Well-defined strains can be also provided for our clients to manufacture fermented products in a cost-effective way.
Features
Ready-to-use product, accelerating research progress, enhancing application performance.
Synonyms
arabinosidase (ambiguous); α-arabinosidase; α-L-arabinosidase; α-arabinofuranosidase; polysaccharide α-L-arabinofuranosidase; α-L-arabinofuranoside hydrolase; L-arabinosidase (ambiguous); α-L-arabinanase
Function
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.

Unit Definition
One Unit of α-L-arabinfuranosidase activity is defined as the amount of enzyme required to release one μmole of p-nitrophenol (p-NP) per minute from p-nitrophenyl-α-L-arabinofuranoside (2.5 mM) in sodium acetate buffer (100 mM).
Reaction
Hydrolysis of terminal non-reducing α-L-arabinofuranoside residues in α-L-arabinosides.
