Aplicação
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.
Ações bioquímicas/fisiológicas
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.
Definição da unidade
One unit will liberate 1.0 μmole of isomaltose (measured as maltose) per min at pH 6.0 at 37 °C, using dextran as substrate.
forma física
Partially purified, lyophilized powder

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
