Application
β-Amylase from sweet potato has been used:
- as a molecular weight marker in blue native polyacrylamide gel electrophoresis (PAGE)
- as a standard for calibration curve preparation in size exclusion chromatography
- as a model protein for small-angle X-ray analysis (SAXs)
Biochem/physiol Actions
β-Amylase acts on the polysaccharide α(1,4) glycosidic linkages and releases maltose present in the non-reducing ends. Due to its stability, β-Amylase from sweet potato is used in the immobilized enzyme preparation in combination with agarose beads.
