β-Amylase from Barley

β-Amylase from Barley

Cat No:PDE-0016

Description

Beta-amylase hydrolyzes alpha -(1,4) glucan bonds in polysaccharides that have three or more alpha -(1,4) linked D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose. The preparation of pure crystalline β-amylase consists of four isoenzymes with different isoelectric points. In the absence of a reducing agent, the enzyme polymerizes rapidly through sulfhydryl groups. P-chlorotoluate inhibits polymerization and enzyme activity. The reducing agent mercaptoethanol or dithiothreitol can completely restore the activity.
