Medium-temperature α-Amylase

Alpha amylase (EC 3.2.1.1), also known as a-1,4-glucan-4-glucan hydrolase, is a starch endonuclease that uses starch as a substrate. When it interacts with starch, it cleaves the a-1,4-glycoside bond from within the molecule, causing a rapid decrease in starch molecular weight. Alpha amylase cannot cleave the a-1,6-glycosidic bond at the branching point of branched starch, nor can it cleave the a-1,4-glycoside bond near the a-1,6-glycosidic bond. Therefore, in addition to glucose and maltose, the hydrolysis product also contains dextrin and a series of oligosaccharides containing a-1,6-glycosidic bonds.This product is fermented by Bacillus subtilis and has the characteristics of high enzyme activity, good heat resistance, wide pH range, no additives, and no toxic side effects.Definition of enzyme activity
