Beschreibung
Zusammenfassung:	Carbonic anhydrase and carbonic anhydrase complex of the present invention use carbonic anhydrase derived from microorganisms with excellent economic efficiency and improve thermal stability by a method for forming spontaneous covalent bonds through protein recombination, to maintain enzyme activity even in high-temperature environments ranging from 40 to 60℃. Therefore, by using the carbonic anhydrase and carbonic anhydrase complex of the present invention, provided is an effect of improving the economic efficiency and CO_2 capturing efficiency of a system to capture CO_2 from combustion gas of coal and natural gas-fired power plants using the enzyme. 본 발명의 탄산탈수효소 및 탄산탈수효소 복합체는 경제성이 우수한 미생물 유래 탄산탈수효소를 사용하며 단백질 재조합을 통해 자발적인 공유결합이 형성되도록 하는 방법으로 열안정성을 향상시켰으므로 40 내지 60℃에 달하는 고온 환경에서도 효소 활성이 유지되는 장점이 있다. 따라서 본 발명의 탄산탈수효소 및 탄산탈수효소 복합체를 사용하면 상기 효소를 이용하여 석탄 및 천연 가스 화력발전소의 연소가스로부터 CO2를 포집하는 시스템의 경제성 및 CO2 포집효율을 향상시킬 수 있는 효과가 있다.
