T7 promoter without RBS

This part is the T7 promoter without RBS. It has been reported that T7 promoter doesn't work with E.coli RNA polymerase, but only with T7 RNA polymerase(T7RNAP). However, we observed leakage of it in the absence of T7RNAP.

Summary: We confirmed that sfGFP (BBa_I746916) is available in constructs driven by the pR (BBa_R0051) and determined the relationship between sfGFP protein concentration and fluorescence intensity. Besides, we made a comparison fluorescence intensity of between BBa_K3098015 and BBa_I746916.
Documentation: We constructed a recombined plasmid composed of pR (BBa_R0051)+RBS (BBa_B0030)+sfGFP (BBa_I746916)+6xHis-tag to express the sfGFP (BBa_I746916). By the way, there was not repressor CI of pR in the expression system.
