Activity
~ 10 U/mg (40°C, pH 4.0 on CM-linear 1,5-α-L-arabinan).
Unit Definition
One Unit of arabinanase activity is defined as the amount of enzyme required to release one µmole of arabinose reducing-sugar equivalents per minute from CM-linear 1,5-α-L-arabinan (6 mg/ml) in sodium acetate buffer (200 mM), pH 4.0 at 40°C.
Reaction
Endohydrolysis of (1→5)-α-arabinofuranosidic linkages in (1→5)-arabinans
