일반 설명
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).
애플리케이션
α-Amylase has been used:
- as a control enzyme in agar plate-based and carboxymethylcellulose-based clearing assays to screen cellulase activity
- for the hydrolysis of starch to explore the the role of wheat starch in frozen dough
- to inhibit Staphylococcus aureus biofilms
생화학적/생리학적 작용
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.
단위 정의
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).

We have cloned three genes (amy1, amy2 and amy3) encoding alpha-amylase in the filamentous fungus Aspergillus oryzae. The established overall sequences have a very high degree of homology, showing divergences mainly in the 3'-untranslated regions. The positions and the sequences

In higher plants the production of starch is orchestrated by chloroplast-localized biosynthetic enzymes, namely starch synthases, ADP-glucose pyrophosphorylase, and starch branching and debranching enzymes. Diurnal regulation of these enzymes, as well as starch-degrading enzymes, influences both the levels and composition
