Abstract
Description
마지막으로, 상기한 변환 최적 조건은 실험적으로 확인된다. 흔히, (만약 존재한다면) 반응 속도 조절 단계(rate-limiting step)를 확인하는 것이 변환 최적 조건을 미세 조정(fine-tuning)하는 데에 유용하다. 항온처리 시간이 경과함에 따라 환원된 형태가 지속적으로 축적이 된다는 것은, 산화 단계가 반응 속도 조절 단계라는 것을 나타낸다. 축적이 발생하면, 산화에 보다 우호적인 조건들(예를 들면, 산소, 높은 pH, 높은 온도)을 적용하여 목적하는 형태의 형성을 최대화하여야 한다. 목적하는 형태의 형성률이 매우 크지만 낮은 수준의 환원된 단백질이 항상 존재하는 경우, 제거 단계가 반응 속도 조절 단계이다. 이러한 경우, 상기한 제거 단계가 향상되도록 항온처리 조건을 변화시켜 목적하는 형태의 단백질 형성을 최대화할 수 있다.
