Amylase catalyzes the hydrolysis breaking down of starch, glycogen and related polysaccharides into more simple and readily usable forms of sugar. The enzyme amylase is able to hydrolyze 1,4 bonds, while a-1,6-glucosidase hydrolyzes the 1,6 bonds.
Webamylase, any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules). Three categories of amylases, denoted alpha, beta, and gamma, differ in the way they attack the bonds of the … Starch molecules are too large to enter the bacterial cell,so only bacteria that secrete exoenzymes (α -amylase and oligo-1,6-glucosidase)are able to hydrolyze starch into subunits (dextrin, maltose, or glucose). These molecules are readily transported intothe bacterial cell to be used in metabolism.
