pathogenesis-related 10 단백질의 RNase 활성의 특징은 무엇인가? | (1994)은 인삼에서 분리한 ribonuclease의 아미노산 서열과 PR-10 단백질이 높은 상동성을 가지며 발현 양상이 유사하여 PR-10 단백질이 가지는 RNase 활성이 방어 반응과 관련된다고 하였다. 이러한 RNase활성은 병원체 감염 부위의 세포자살(programmed cell death) 또는 병원체에 대해 직접적으로 작용함으로써 식물체를 보호하는 것으로 생각되며 in vitro 실험을 통하여 Bet v 1 (Bufe et al.1996), LaPR-10 (Bantignies et al. | |
PR-10 단백질은 일반적으로 어디에 존재하며 형태는 어떠한가? | 1986) PR-10 단백질은 병원체에 대한 방어 뿐만 아니라 식물의 발달에도 관여하며(Sikorski et al. 1999) 대부분의 PR 단백질은 세포외에 존재하는 반면 PR-10 단백질은 일반적으로 세포내에 존재하며 16 ~ 19 kDa의 작은 크기의 산성 단백질이다(Liu and Ekramoddoullah. 2006). | |
pathogenesis-related (PR) 단백질은 어떻게 유도 되며 몇가지의 분류가 있는가? | 식물은 곰팡이, 박테리아, 바이러스와 같은 다양한 병원 체에 끊임없이 노출되며 방어반응에 관련된 단백질의 발현을 유도한다. 이러한 단백질 중 pathogenesis-related (PR) 단백질은 병원체와 환경스트레스 의해 유도되는 것으로 알려져 있으며(Van Loon and Van Strien. 1999) 단백질의 구조와 생화학적 활성에 기초하여 17개의 family로 분류되어 있다(Sels et al. 2008). |
