产品说明 应用 Dextranase from Penicillium sp. can be used to modify alternan. Dextranase from Penicillium sp. has also been used in a study that explored the possibility that the Dex protein might adopt a fold unfamiliar to any known structure. 包装 500, 1000 units in poly bottle 生化/生理作用 The product is an endodextranase that hydrolyzes α-(1,6)-glucosidic linkages in dextran. Dextrans are undesirable compounds synthesized from sucrose by microbial contaminants during sugar production. They increase viscosity of the flow and decrease industrial recovery. Dextranase has been used for hydrolyzing dextran at sugar mills in order to improve efficiency of sugar production. 单位定义 One unit will liberate 1.0 μmole of isomaltose (measured as maltose) per min at pH 6.0 at 37 ℃, using dextran as substrate. 外形 Partially purified, lyophilized powder 其他说明 更多关于复杂碳水化合物分析酶的信息请见 www.sigma-aldrich.com/enzymeexplorer 基本信息

产品说明 一般描述 Dextranase is generated by many microorganisms, including bacteria, filamentous fungi, and yeast. 应用 Dextranase from Chaetomium erraticum has been used:
生化/生理作用 Dextranase is an endodextranase that hydrolyzes α-(1,6)-glycosidic linkages in dextran. It has many industrial and clinical applications such as food processing, sugar modification, and medicine preparation. Dextranase is widely used to produce alternated sugar beet and isomaltooligosaccharides (IMOs), a prebiotic functional food. The low molecular weight dextran obtained from dextranase serves as a synthetic blood volume expander. Dextranase can be coupled to antibodies for the detection of tumor cells. It prevents the occurrence of dental plaques by depolymerizing microbial dextran deposits in teeth. Hence, it is used in dental care products. 制备说明 通过Chaetomium erraticum的深层发酵产生的一种真菌葡聚糖酶。 分析说明 在pH 3-7范围内以及最高约70 ℃的温度下稳定。对于绝大多数应用，比较适合的条件是pH 5-6且 50-60 ℃的温度。 其他说明 更多关于复杂碳水化合物分析酶的信息请见www.sigma-aldrich.com/enzymeexplorer 基本信息
