應用
来自青霉属的葡聚糖酶可用于修饰Alternan。来自青霉属的葡聚糖酶还用于一项研究中，该研究探索了Dex蛋白可能采用任何已知结构都不熟悉的折叠的可能性。
生化／生理作用
该产品为一种水解葡聚糖中α-(1,6)-α-葡糖苷键的内葡聚糖酶。葡聚糖是通过在糖生产过程中微生物污染物从蔗糖中合成的不良化合物。它们会增加流动的粘度，降低工业的回收率。葡聚糖酶已在糖厂用于水解葡聚糖，以提高糖生产的有效性。
單位定義

The DEX gene encodes an extracellular dextranase (EC 3.2.1.11); this enzyme hydrolyzes the alpha(1,6) glucosidic bond contained in dextran to release small isomaltosaccharides. Sequence analysis has revealed only one homologous sequence, CB-8 protein, from Arthrobacter sp., with 30% sequence identity.

Alternan is a unique glucan with a backbone structure of alternating alpha-(1 --> 6) and alpha-(1 --> 3) linkages. Previously, we isolated strains of Penicillium sp. that modify native, high molecular weight alternan in a novel bioconversion process to a

Multiple forms of native and recombinant endo-dextranases (Dexs) of the glycoside hydrolase family (GH) 66 exist. The GH 66 Dex gene from Streptococcus mutans ATCC 25175 (SmDex) was expressed in Escherichia coli. The recombinant full-size (95.4 kDa) SmDex protein was digested

Alpha-dextranase, which can hydrolyze dextran, is largely used in the sugar industry. However, a thermostable alpha- dextranase is needed to alleviate the viscosity of syrups and clean blocked machines. Thus, to improve the optimal temperature of Lipomyces starkeyi alpha-dextranase expressed
