ISOLATION AND PROPERTIES OF CRYSTALLINE (r-AMYLASE FROM GERMINATED BARLEY*
The isolation of crystalline ar-amylase has been reported in a preliminary communication (1). Details of the method of isolation, behavior of the fractions leading to crystallization, and some properties of the crystalline material are reported here. This material constitutes the first instance of the crystallization of an cu-amylase from a higher plant and is probably the only protein crystall...
متن کاملIsolation, Optimization and Characterization of α- Amylase from Bacillus alcalophilus
Amylase is one of the most important enzymes widely used in paper, textile, pharmaceutical industries etc. In the present investigation a thermostable, alkalophilic amylase was isolated from underlying soil samples of domestic wastes, and was screened on starch agar medium. The amylase activity was measured using colorimetric method at 540nm. Among forty five isolates, thirteen demonstrated cle...
متن کاملEnzyme Assay Guided Isolation of an α-Amylase Inhibitor Flavonoid from Vaccinium arctostaphylos Leaves
The management of postprandial hyperglycemia is an important strategy in the control of diabetes mellitus and complications associated with the disease, especially in the diabetes type 2. Therefore, inhibitors of carbohydrate hydrolyzing enzymes can be useful in the treatment of diabetes and medicinal plants can offer an attractive strategy for the purpose. Vaccinium arctostaphylos leaves are c...

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
