Activating Compound

EC Number Activating Compound Comment Organism Structure
2.4.1.19 light illumination of the enzyme with white, linearly polarized light and at constant 25°C increases the enzyme activity producing a mixture of alpha-, beta-, and gamma-cyclodextrins. At a high enzyme concentration of 0.64 U/cm3, regardless the illumination time, formation of beta-cyclodextrin predominates. The highest yield of beta-cyclodextrin is afforded after 1 h illumination, but 2 h illumination leads to a significant increase in the yield of gamma-cyclodextrin Thermoanaerobacter sp.
