Content: 400 Units
Shipping Temperature: Ambient
Storage Temperature: 2-8oC
Formulation: In 3.2 M ammonium sulphate
Physical Form: Suspension
Stability: Minimum 1 year at 4oC. Check vial for details.
Enzyme Activity: endo-Arabinanase
EC Number: 3.2.1.99
CAZy Family: GH43
CAS Number: 75432-96-1
Synonyms: arabinan endo-1,5-alpha-L-arabinanase; 5-alpha-L-arabinan 5-alpha-L-arabinanohydrolase
Source: Aspergillus niger
Molecular Weight: 39,750
Concentration: Supplied at ~ 200 U/mL
Expression: From Aspergillus niger
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.
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 (10 mg/mL) in sodium acetate buffer (100 mM), pH 4.0 at 40oC.
Temperature Optima: 40oC
pH Optima: 4
Application examples: Applications established in food and beverage industries, particularly in the reduction of haze in fruit juices and the processing of sugar beet.
