Part:BBa_R0011

Promoter (lacI regulated, lambda pL hybrid)

Inverting regulatory region controlled by LacI (BBa_C0010, BBa_C0012, etc.) The PLlac 0-1 promoter is a hybrid regulatory region consisting of the promoter P(L) of phage lambda with the cI binding sites replaced with lacO1. The hybrid design allows for strong promotion that can nevertheless be:

• repressed by LacI, the Lac inhibitor (i.e. repressor) (BBa_C0012) ([LUTZ97]).
• induced by [http://openwetware.org/wiki/IPTG IPTG] in E.Coli DH5-alpha-Z1 (same paper reference) over a >600-fold range

Intrinsic Noise Value: 0.0040 (compare with R0010: 0.0707; R0051: 0.0869). See [http://2015.igem.org/Team:William_and_Mary William_and_Mary iGEM 2015]

Usage and Biology

Strong promoter. [jb, 5/24/04]

R0011 will be on in strains without lacI, off in strains that are lacIq (ie. Part:BBa_V1003) and medium in strains that are lacI
