Native Sweet potato β-Amylase

inquiry

Cat No.

NATE-0762

Description

β-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. Pure, crystalline β-amylase preparation consists of four isoenzymes with different isoelectric points. The enzyme polymerizes very rapidly through the sulfhydryl groups in the absence of reducing agents. p-Chloromercuribenzoate inhibits the polymerization and the enzymatic activity. The reducing agents mercaptoethanol or dithiothreitol can completely restore the activity.

Abbr

β-Amylase, Native (Sweet potato)

Alias

β-amylase

Source

Sweet potato

Applications

β-Amylase is used to hydrolyze α bonds of α-linked polysaccharides, such as starch and glycogen. β-Amylase, from Creative Enzymes, has been used in various plant studies, such as carbon starvation studies in Populus tremuloides. β-amylase from sweet potato has been used to examine the utility of the enzyme in inhibiting and removing Staphylococcus aureus biofilms. The enzyme has also been used to prepare β-limit dextrin from waxy maize starch.
