Abstract:
본 발명은 롱(long) PCR이 가능한 돌연변이 DNA 중합효소 및 이의 유전자들에 관한 것으로서, 보다 상세하게는 써모코커스 속 ( Thermococcus sp.) 균주로부터 유래하고 야생형 TNA1_pol DNA 중합효소를 돌연변이화 하여 긴(long) PCR 중합반응에 유용한 DNA 중합효소, 상기 돌연변이 DNA 중합효소를 암호화하는 유전자 및 이를 이용한 중합효소 제조방법에 관한 것이다. 본 발명의 돌연변이 DNA 중합효소는 기존의 야생형이나 돌연변이형에 비해 긴(long) 사슬의 DNA에 대한 PCR에 있어서 월등한 성능을 나타냄으로써 인간의 유전체 분석 등 긴 사슬의 증폭이 필요한 다양한 분야에 널리 응용될 수 있다.
