EC 3.2.1.2
CAZy Family: GH14
CAS: 9000-91-3
Synonyms: β-amylase; 4-α-D-glucan maltohydrolase
From barley flour. Crystalline.
In 3,2 M ammonium sulphate.
E-BARBL-50KU: Supplied at ~ 10,000 U/mL.
E-BARBL-100KU: Supplied at ~ 10,000 U/mL.
Specific activity:
~ 600 U/mg (40°C, pH 6,0 on soluble starch).
Powder enzyme form (2000°L) is for use in AACC and ASBC α-amylase assay procedures (see E-BARBP-2G or E-BARBP-5G).
Stability: > 4 years at 4°C.
Unit definition:
One Unit of β-amylase activity is defined as the amount of enzyme required to release one µmole of maltose reducing-sugar equivalents per minute from soluble starch (10 mg/mL) in sodium phosphate buffer (200 mM), pH 6,0 at 40°C.
Specificity:
Hydrolysis of α-1,4-D-glucosidic linkages in polysaccharides releasing maltose units from the non-reducing end.
