Abstract
본 발명은 유전자조작을 이용하여 사람의 프로인슐린 융합단백질을 생산하는 데 있어서 프로인슐린 융합단백질의 안정성과 발현율을 증가시키는 방법에 관한 것이다.The present invention relates to a method for increasing the stability and expression rate of proinsulin fusion proteins in producing human proinsulin fusion proteins using genetic engineering.
먼저 사람 프로인슐린 유전자를 cDNA 클로닝 방법으로 대장균 속주의 클로닝하였다. 클로닝된 사람 프로인슐린 유전자를 Lac 리보솜 결합부위 유전자, (Thr)6코딩하는 유전자와 함께 pUC8에 도입 [pUC8-(Thr)6-PI]하였고, pUC8-(Thr)6-PI와 pEX2로 터 pYK10-9 발현벡터를 제조하였다.First, the human proinsulin gene was cloned into the E. coli strain by the cDNA cloning method. The cloned human proinsulin gene was introduced into pUC8 with the Lac ribosomal binding site gene, (Thr) 6 encoding [pUC8- (Thr) 6- PI], and the pUC8- (Thr) 6- PI and pYK10 from pEX2 An -9 expression vector was prepared.
프로인슐린 전서열이 짧은 pYK10-9 벡터가 도입된 대장균에서도 발현되 융합 단백질은 대장균 세포내에서 안정하였다. pYK10-9 발현벡터가 형질전환된 대장균 pop2136은 플라스크 발효에서 249mg/1의 사람 프로인슐린 융합단백질을 생성하였고, 이 균을 유가배양한 결과 생성된 프로인슐린의 양은 2.2g/l로 현저히 증하하였다.The fusion protein was also expressed in E. coli cells in which Escherichia coli with a short pYK10-9 vector was introduced. Escherichia coli pop2136 transformed with pYK10-9 expression vector produced 249 mg / 1 human proinsulin fusion protein in flask fermentation.
