Activating Compound

Activating Compound Comment Organism Structure
additional information an assembly of ManB with mini-CbpA, which contains a carbohydrate-binding module that provides proximity to insoluble substrates, increases the activity toward galactomannan from locust bean gum and guar gum 1.7- and 2.0fold over those without mini-CbpA Clostridium cellulovorans

Application

Application Comment Organism
degradation when assembled with the mini-CbpA, which contains a carbohydrate-binding module that provides proximity to insoluble substrates, a mixture of endoglucanase E and ManB at a molar ratio of 1:2 shows the highest synergistic effect of 2.4fold on locust bean gum degradation. The mixture at a ratio of 1:3 shows the highest synergistic effect of 2.8fold on guar gum Clostridium cellulovorans
