General description

β-Amylase from sweet potato is a tetrameric enzyme with each monomer comprising (α/β) core domain and a C-terminal loop region.[1] It belongs to the glycoside hydrolase family GH14.[2]
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives . This product belongs to category of Re-engineered products, showing key improvements in Green Chemistry Principles “Waste Prevention”, “Safer Solvents and Auxiliaries” and “Design for Energy Efficiency”. Click here to view its DOZN scorecard.

Application

β-Amylase from sweet potato has been used:
  • as a molecular weight marker in blue native polyacrylamide gel electrophoresis (PAGE)[3]
  • as a standard for calibration curve preparation in size exclusion chromatography[4]
  • as a model protein for small-angle X-ray analysis (SAXs)[5]

Biochem/physiol Actions

β-Amylase acts on the polysaccharide α(1,4) glycosidic linkages and releases maltose present in the non-reducing ends.[2] Due to its stability, β-Amylase from sweet potato is used in the immobilized enzyme preparation in combination with agarose beads.[6]
