DESCRIPTION

endo-1,5-α-arabinanase (Aspergillus niger)

EC 3.2.1.99
CAZy Family: GH43
CAS: 75432-96-1

Synonyms
arabinan endo-1,5-alpha-L-arabinanase; 5-alpha-L-arabinan 5-alpha-L-arabinanohydrolase

Form:
In 3.2 M ammonium sulphate.

Stability:
> 2 years at 4oC.

Specific activity:
~ 10 U/mg (40oC, 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 40oC.

Specificity:
endo-hydrolysis of (1,5)-α-arabinofuranose linkages in (1,5)-α-arabinans. Acts more slowly on the (1,5)-α-linked arabinan backbone in branched arabinans than on linear arabinans.

Applications:
Applications established in food and beverage industries, particularly in the reduction of haze in fruit juices and the processing of sugar beet.
