Insects and fungi share a long history of association in various habitats, including the wood-decomposition niche. Fungal mimicry of termite eggs is one of the most striking evolutionary consequences of insect-fungus association. Termites of the genus Reticulitermes often harbor fungal

A gene encoding a beta-1,3-1,4-glucanase (CelA) belonging to family 5 of glycoside hydrolases was cloned and sequenced from the Bacillus subtilis A8-8. The open-reading-frame of celA comprised 1499 base pairs and the enzyme was composed of 500 amino acids with

Two kinds of 4,6-dimethoxy-1,3,5-triazine (DMT) oligoxyloglucans, DMT-beta-XXXG and DMT-beta-XLLG, have been synthesized via one-step procedure starting from the corresponding unprotected oligoxyloglucans in water. The resulting DMT derivatives were found to be hydrolyzed by endo-beta-1,4-D-glucanase III from Trichoderma reesei (EGIII) and

The cDNA encoding β-1,3(4)-glucanase, named PsBg16A, from Paecilomyces sp. FLH30 was cloned, sequenced, and over expressed in Pichia pastoris, with a yield of about 61,754 U mL⁻¹ in a 5-L fermentor. PsBg16A has an open reading frame of 951 bp

In vitro evolution methods are often used to modify protein with improved characteristics. We developed a directed evolution protocol to enhance the thermostability of the beta-1,3-1,4-glucanase. The thermostability of the enzyme was significantly improved after two rounds of directed evolution.

Questions

  1. I would like to know if this product digest beta 1-4 glucan or beta 1-3 glucan or both.

    1 answer
    1. As mentioned in the 'DESCRIPTION' section of the product page, under 'Biochem/physiol Actions', this product specifically degrades ?-1,4-glucans. Should a glucanase that degrades beta 1-3 glucan be required, please see product 67138 at the link below:
