Specific 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 (10 mg/mL) in sodium acetate buffer (100 mM), pH 4,0 at 40°C

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

Temperature optima40°C
pH optima: 4

Stability: minimum 1 year at 4oC
  • High purity and stability
- Research, biochemical enzyme assays and in vitro diagnostic analysis
- Food and beverage industries, particularly in the reduction of haze in fruit juices and the processing of sugar beet
