Application

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.

Biochem/physiol Actions

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.

Physical form

Partially purified, lyophilized powder

Other Notes

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.

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

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.

The bacterial strain PP710, isolated from soil and identified as Paenibacillus species, produced a low-digestibility alpha-glucan containing a large amylase-resistant portion. This alpha-glucan was obtained in high yields from maltodextrin (dextrose equivalent 3) by using the condensed culture supernatant of
