Product Name

α-Amylase from porcine pancreas

General deion

Molecular mass: 51-54 kDa.

α-Amylase isolated from porcine pancreas is a glycoprotein. It is a single polypeptide chain of ~475 residues containing two SH groups and four disulfide bridges and a tightly bound Ca₂₊necessary for stability. Chloride ions are necessary for activity and stability. The pH range for activity is 5.5 to 8.0, with the pH optimum at 7.

l Biological Information

Biochem/Physiol Actions

α-Amylase hydrolyzes the α-(1,4) glucan ages in polysaccharides of three or more α-(1,4) ed D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose. α -Amylase, from porcine pancreas, is a glycoprotein that consists of a single polypeptide chain of approximately 475 residues containing 2 SH groups and four disulfide bridges and a tightly bound Ca₂₊ necessary for stability.

Application

α-Amylase is used to hydrolyze α bonds of α-ed polysaccharides, such as starch and glycogen. α-Amylase has been used in various plant studies, such as metabolism studies in Arabidopsis.

Preparation Note

2× crystallized

Unit Definition
