| 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. |
