Allgemeine Beschreibung

Molekülmasse: 51–54 kDa.
α-Amylase, isoliert aus Schweine-Pankreas, ist ein Glykoprotein. Sie ist eine einzelne Polypeptidkette von ~475 Resten, die zwei SH-Gruppen und vier Disulfidbrücken sowie dicht gebundenes Ca2+ für die Stabilität enthält. Chloridionen sind notwendig für Aktivität und Stabilität. Der pH-Wertbereich für Aktivität beträgt 5,5 bis 8,0, wobei der optimale pH-Wert bei 7 liegt.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch ethanol research. For more information see the article in biofiles.

Anwendung

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

Biochem./physiol. Wirkung

α-Amylase hydrolyzes the α-(1,4) glucan linkages in polysaccharides of three or more α-(1,4) linked 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.

Einheitendefinition
