EcN(T7) strain大肠杆菌益生菌工程菌株

A new E. coli strain for efficient production of heme proteins and heme-derived molecules using T7-promoter based expression vectors. The new EcN(T7) strain enables the use of a broader spectrum of expression vectors, as well as the co-expression of genes using the pDuet expression vectors, for expressing heme containing proteins. By utilizing E. coli strains EcN and EcN(T7), capable of being fed heme, the rate limiting step of heme biosynthesis in E. coli is eliminated, thereby permitting higher heme saturation of heme proteins and also higher yields of heme-derived molecules.
