초록

효모에서 사람의 H-, L-ferritin을 생산하기 위해서, 기존에 복제된 vector를 사용하였으며,단백질을 발현하기 위해서 각각의 증폭된 ferritin 유전자를 GALI promoter에 의해 조절되는 pYES2.1/V5-His-TOPO 효모 발현 vector에 삽입하였다. Western blot 분석을 통해서 사람의 H-, L-ferritin subunits을 함유한 재조합 효모에서 사람의 ferritin이 발현된 것을 확인할 수 있었다. 또한 Atomic absorption spectrometry(AAS) 분석을 통해서 형질변환된 효모의 철 함유량이 대조군과 비교하여 $1.6{\sim}l.8$배 증가한 것을 확인하였다. 향후 ferritin이 함유된 형질변환 효모를 사용하여 잠재적으로 철이 강화된 영양성분을 기능성 식품과 사료에 이용할 수 있을 것이다.

To produce human ferritins in yeast, human H-chain and L-chain ferritins were amplified from previously cloned vectors. Each amplified ferritin gene was inserted into the pYES2.1/V5-His-TOPO yeast expression vector under the control of the GAL1promoter. Western blot analysis of the recombinant yeast cells revealed that H-and L-chain subunits of human ferritin were expressed in Saccharomyces cerevisiae. Atomic absorption spectrometry (AAS) analysis demonstrated that the intracellular content of iron in the ferritin transformant was 1.6 to 1.8-fold higher than that of the control strain. Ferritin transformants could potentially supply iron-fortified nutrients for food and feed.
