General description
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.
