New enzymatic carbon dioxide capture from exhaust fumes.CO2 is the most abundant greenhouse gas, its elimination crucial to slow down global warming. So, reduction of CO2 is one of the most important challenges for an eco-friendly and sustainable production of energy. Carbonic Anhydrases (CA) are a family of metalloenzymes that catalyze the conversion of carbon dioxide to carbonic acid: CO2 + H2O -> H2CO3. Nature already found a solution as CA enables cells to fix carbon, regulate pH and process ion transport. ChallengeConventional solvent technologies for CO2 elimination with chemical promoters have disadvantageous properties such as being corrosive, volatile and toxic. Thus, there is an unmet need for alternative solutions.
Our SolutionScientists at the University of Göttingen isolated, cloned and characterized a new member of carbonic anhydrase (CA) for use as a new biocatalytic approach for CO2 fixation. This unique CA was isolated form a marine sponge.
The new CA (Astrosclerin-3) is as powerful as common bovine CA. Wilbur-Anderson activity assay (A) and successful over-expression and purification of Astrosclerin-3 (B). X = inhibitor for CA. Source: Prof. Dr. Daniel Jackson. Advantages
