General description
Microbial amylases are exoenzymes and are used in several industrial applications, such as production of bread, maltose syrups, and fermentation of soya sauce, miso etc. α-Amylase isolated from Aspergillus oryzae has been found to have molecular weights of 51kDa (sedimentation and diffusion) and 49kDa (gel filtration).
Application
Biochem/physiol Actions
Aspergillus oryzae α-amylase (Ao α-amylase) enzyme catalyzes the hydrolysis of the α-1,4 glycosidic bonds in soluble starches and related subsrates. These substrates are broken down to release short oligosaccharides and α-limit dextrins.[4]
Other Notes
1 U corresponds to the amount of enzyme which liberates 1 μmol maltose per minute at pH 6.0 and 25°C (starch acc. to Zulkowsky, Cat. No. 85642, as substrate).
For the determination of fats in food; Application in (selective) hydrolysis/condensation of glycosidic bonds.
