Abstract
For the practical use of nuecin protein, we tried to overexpress nuecin using Bm5 insect cell and Bombyx mori. We inserted nuecin cDNA into pBm10po1-Xa vector derived from B. mori nuclear polyhedrosis virus (BmNPV), and expressed in Bm5 cells and B. mori respectively. SDS-PAGE and Northern blot analysis showed an expressed of the protein when baculovirus expression vector system (BEVS) was used. The amount of intracellular protein is abundant, but the amount of extracellular protein is poor. The results suggest that the biologically active nuecin protein produced by using BEVS is poor because incresed level of misfolded nuecin by the strong promoter, polyhedrin and p 10 of BEVS, decrease the level of free chaperons and foldases by binding with them.
