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.

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
