2024年10月8日 · Glucoamylases are amongst the main enzymes that are involved in the hydrolysis of starch. They are exo-acting enzymes that tend to release consecutive glucose units from the starch molecules’ non-reducing ends. Glucoamylases are known as microbial enzymes which are present in bacteria, fungi, and archaea but not in animals and plants.

糖化酶，又称 葡萄 糖淀粉酶 [Glucoamylase, (EC.3.2.1.3.)]它能把淀粉从非还原性未端水解a-1.4葡萄糖苷键产生葡萄糖，也能缓慢 水解 a-1.6葡萄糖苷键，转化为葡萄糖。 同时也能水解糊精，糖原的非还原末端释放β-D-葡萄糖。 糖化酶用于以 葡萄糖 作 发酵培养基 的各种抗生素、 有机酸 、 氨基酸 、维生素的发酵；本品还大量用于生产各种规格的葡萄糖。 总之，凡对淀粉、糊精必需进行酶水解的工业上，都可适用。 糖化酶的底物专一性较低，它除了能从淀粉链的非还原性未端 …

Maltase-glucoamylase is an alpha-glucosidase digestive enzyme. It consists of two subunits with differing substrate specificity. Recombinant enzyme studies have shown that its N-terminal catalytic domain has highest activity against maltose, while the C-terminal domain has a broader substrate specificity and activity against glucose oligomers.

葡萄糖淀粉酶（glucoamylase）又称γ-淀粉酶（gamma-amylase）、淀粉葡糖苷酶（amyloglucosidase，AMG），全名葡聚糖 1,4-α-葡糖苷酶，是一種酸性的單鏈外切型糖苷 水解酶，不僅能催化澱粉水解為葡萄糖，還能從澱粉糖鏈的非還原末端 (即不可以形成半縮醛的羥基) 切下 ...

Maltononaose 是一种由 9 个葡萄糖单元通过 α-1,4-糖苷键连接而成的线性寡糖。Maltononaose 被用作研究葡萄糖淀粉酶 (glucoamylase) 的底物，以研究该酶的结合位点 (subsites) 亲和力。Maltononaose 可以用于淀粉酶的活性测定和优化淀粉水解过程的研究。

Glucoamylase is one of the oldest and widely used biocatalysts in food industry. The major application of glucoamylase is the saccharification of partially processed starch/dextrin to glucose, which is an essential substrate for numerous fermentation processes and a range of food and beverage indust …

Glucan 1,4-α-glucosidase (EC 3.2.1.3, glucoamylase, amyloglucosidase, γ-amylase, lysosomal α-glucosidase, acid maltase, exo-1,4-α-glucosidase, glucose amylase, γ-1,4-glucan glucohydrolase, acid maltase, 1,4-α-D-glucan glucohydrolase) is an enzyme located on the brush border of the small intestine with systematic name 4-α-D-glucan ...

糖化酶全名为葡萄糖淀粉酶，又称淀粉α-1.4葡萄糖苷酶或Y-淀粉酶，是一种单链酸性糖苷水解酶，具有外切酶活性的胞外酶。 因为在发酵作业中主要用作将淀粉转化为葡萄糖，所以习惯上被称为糖化酶。 糖化酶是世界上生产量最大、应用范围最广的酶制剂，其不仅用于酒类和酒精生产，还广泛应用于葡萄糖、糖浆、味精等生产。 东恒华道生产的糖化酶，是引进美国先进水平的菌种经过现代生物技术精制成而的生物酶制剂，各项指标符合国家标准，质量稳定。 【中文别名】葡萄 …

2000年12月29日 · Glucoamylases are inverting exo-acting starch hydrolases releasing β-glucose from the non-reducing ends of starch and related substrates. The majority of glucoamylases are multidomain enzymes consisting of a catalytic domain connected to a starch-binding domain by an O -glycosylated linker region.

2023年9月1日 · Glucoamylases (GAs) are one of the principal groups of enzymes involved in starch hydrolysis and belong to the glycosylhydrolase family. They are classified as exo-amylases due to their ability to hydrolyze α-1,4 glycosidic bonds from the non-reducing end of starch, maltooligosaccharides, and related substrates, releasing β-D-glucose.
